The stalactitic calcites are from an occurrence similar to the one which produces the Elk Creek (South Dakota) Baryte - they are both from calcareous concretions in the late Cretaceous Pierre shale. There are many exposures of the Pierre shale in Carter County, Montana which can produce these calcites. Many were collected by Bud Ehrle (of Miles City, MT), from undisclosed locations in Carter County, and sold by various dealers including Black Hills Institute (my company). Alzada is the the only town in southern Carter County, and is near some of the Pierre shale exposures where these can be found.

This locality was worked back in the 60s for calcite specimens by Ed McDole.

Does anyone know anything about this occurrence? Is it a mine, cave? or what?. Any associated minerals?

Montclair is the name of a town in New Jersey and the name of a particular quarry in that town. It is one of many basalt quarries in the Watchung Mountains, if you wish to dignify them with the term mountain. It has been familiar to mineral collectors that live in the region for generations and like other trap rock quarries in the region has intermittently produced specimens with the intermittent blessings of the companies that work these quarries for road metal and construction material. Sometimes the specimens have been recovered by the quarry workers but most of the specimens have been recovered by enthusiastic, hard working mineral collectors and rockhounds who sometimes know what they are doing. Montclair, like the other basalt quarries in the region are known for the zeolite and related minerals that they produce from amygdaloidal cavities. Sometimes they produce nice calcite specimens which are often cunningly associated with other mineral species. The variety of specimens shown here from Montclair and the other quarries is by no means exhaustive and as more fine specimens from these localities are photographed and uploaded to Mindat they will be added to the article.

The trap rock quarries of the Watchungs combined with the nearby unique zinc mines at Franklin & Sterling Hill New Jersey is one of the pivotal areas near large population centers that were key to developing mineralogy and promoting mineral collecting as a hobby and an avocation. New Jersey is the mostly densely populated state in the union, and lies just across the Hudson River from New York city and convenient for millions for day trips. It made a perfect breeding ground for collectors, and mineralogists of every kind. I can't count the number of well known collectors, dealers and mineralogists and mineral museum curators that got their start among the trap rock quarries of the Watchungs or in their youth spent more than just a little time trying to ferret out the treasures of the region. I was a ten year veteran mineral collector from the southwest USA before I found my way to the east coast and discovered the blandishments of the new Jersey traps. Although I was involved in much of the early importation of zeolites from the Deccan Traps of India to the USA, which in many ways dwarf the New Jersey production of Zeolite specimens, I still have a soft spot in my heart for the specimens produced in the region and came to appreciate the role they have played in mineralogy and and mineral collecting.

The Bergen Arches is the common name for the railroad cut made by the Erie Railroad in Jersey City, New Jersey that cut through the part of the lower New Jersey Palisades known as Bergen Hill. From 1906 to 1910, 250,000 pounds of dynamite was used to remove 800,000 cubic yards of rock. The Arches were the bridges built over the track line. The whole project was accompanied by huge cost overruns and as you might imagine of such a such a large high profile construction project in a densely populated area, it was a magnet for lookie-loos. The rock that was removed was a specimen rich amygdaloidal basalt (ancient mineralized gas bubbles) and of course, every collector within 100 miles was there collecting when ever they could. Of course every kid with nothing better to do was there watching the proceedings. I can see it now. "Hey mister!, why are you pounding on those rocks?", "Well son, I'm not looking for rocks. See these little pocket in the rocks and these little sparkling white cubes? They are called Apophyllite crystals. There are other kinds that grow with them. Now these little white needles are called natrolite and these are........". OK, you get the picture. That kid could have been someone like John Sinkankas, though this particular dig might have been a few years years before his time. Today the Bergan Arches is an abandoned track line, whose functionality has long sense been replaced by many other tunnels and bridges. Specimens from the Bergan Arches construction site are today quite rare and though at the time, the specimens it produced were considered of good quality, they have been outclassed by so many subsequent finds in from other quarries in the region about the best you can say about them today is that they are "classic", "historical" or "quaint".

Of all the quarries of the Watchung Range, this one at Prospect Park is probably the best known and may have produced more good specimens than the others. This kind of thing is endlessly argued among mineral collectors just like sports fans endlessly argue about things like who is the best Pitcher in baseball or the best all time Quarterback. It has been operating for closer to a hundred years than not and from my limited time spent collecting in the quarry I can attest that it might very well be true. I have heard endless stories about the place. About well known collectors in their youth, running full tilt through the woods in the middle of the night directly into trees while trying to escape the night watchman and of collectors lovering themselves down the rock walls in the night to access crystal bearing pockets opened by that days blasting. I have heard of collectors driving into the quarry when permitted and finding the quarry floor littered with fine specimens of prehnite from a recent blast such that they could fill up their truck in a half an hour. I have been in the quarry after a blast and seen parts of the quarry walls showing many open pockets that from a distance looked like white graffiti on a dark wall. The best pocket I collected was perhaps a meter across, lined with good quality prehnite with nice pale yellow Datolite crystals scattered over it. Though this was eclipsed by what I saw and later collected in some of the basalt quarries of the Deccan Plateau in India, it left an indelible impression. Though it has produced some very nice calcite specimens, a few of which are pictured above, it is better known for its Prehnite specimens and other minerals.

There are few if any decent terminated Calcite crystals to be found at Franklin or Sterling Hill, but what is notable and found in abundance are thousands of tons of massive Calcite. The calcite that is in close proximity to the zinc deposit usually has enough manganese in it to impart a brilliant red fluorescence to the Calcite under ultraviolet light. It frequently has other minerals like Willemite scattered around in it that fluoresce green and other minerals often impart other colors as well. Under ultraviolet light this otherwise drab looking rock is striking and is called Christmas tree rock. Hundreds of tons of this material have been shipped all over the world and I doubt that there is a single museum collection that is without a piece. This, if for no other reason, earns this rather drab looking mineral a place in best minerals.

New Mexico, Taos Co., Picuris District, Trampas, Iceberg claim (Iceberg lode claim)

While prospecting the ridge of hornblende schists south of the Harding mine in 1931, Juan A. Brown of Dixon New Mexico unearthed a calcite deposit beneath two or three feet of overburden. Nor realizing the character or possible worth of the deposit he blasted at the apex of the deposit in order to open it up and revealed calcite of optical grade. The deposit lies about 400 feet southwest of the Harding mine quarry at about 7500 feet altitude. In 1939, a pit of 15 by 20 feet was dug to a depth of about 25 feet. This pit produced about 850 pounds of optical-grade material was mined, trimmed and shipped mostly to the Bausch and Lomb Optical Company. The largest single piece of optical-grade Iceland spar obtained from the deposit by the end of 1939 weighed 5 pounds, 8 oz.

The deposit appeared to lie in a vein bounded by a zone of breccia. Some of the calcite found here was pink and banded and graded into white transparent material, much of which was twinned and of not value for optical work. The author of the American Mineralogist article said that he found several pieces on the dump showing perfect conchoidal cleavage. The mine/pit exposed some very large white opaque calcite crystals, one of which was estimated to weigh about 30 tons. No beautiful terminations here though. It is not known if any pictures of specimens mined from this deposit still exist or not.

This specimen is from an old time find (1906). The crystals were originally violet color, but I suspect that this one has faded out over the years. It is variously describes as being from a military base, a quarry and a cave. Its possible I suppose that it could have been all three.

The little white to cream colored curved dolomite crystals are unambitious in the quarry, and some of the calcites are OK, but what you really want to get from there are some of the beautifully sharp, clean small purple fluorite crystals perched on the dolomite crystals. Good ones are very scarce.

There are countless tons of Sectarian nodules scattered around the world and most of them are made up mostly of calcite. Some of them are more than a meter in diameter. This one just had such a classical shape and ridge pattern that I just had to throw it in till we can get some better ones one to demonstrate what the look like. I am sure as more and better ones are uploaded to Mindat, this one will get switched out for better ones.

The Tristate District is a now abandoned lead mining district that produced huge quantities of galena and zinc ore for more than 100 years. The region was hugely productive of specimens and it is now hard to imagine where they have all disappeared to. I got to collect underground there in my youth in the last days of the district. You would jump in a barrel and get lowered down to a little diesel powered jeep which was near was near the bottom of the shaft. You would get in the jeep and drive off to a collecting site with your peach baskets full of newspapers for wrapping. The little six cm specimen above with Calcite, Galena and little black Sphalerite crystals on "hog chawed" chert was considered almost a throw away specimen and Chink Enders, the independent contract "scab" miner who I had paid to show me around in one of little mines apologized for the miserable collecting. He said if I could come back the following week we would drive over (underground) to some of the other connecting mines where he knew of better collecting and we could get more and better stuff. All I had to do to get the nice specimens was bang a little on the chert brachia and wrap up the pieces I wanted to keep. It usually involved more warping than swinging the hammer. Rooms or caverns lined with foot long or large calcite crystals were nothing unusual.

This is a quarry for road and building material working pillow basalts that is known from time to time to produce "big pockets" of calcite and other zeolite minerals. In 1998 Rudy Tschernich visited the quarry and saw obvious signs of big open pockets 30 feet up on the quarry wall. Not being able to access them he reported them his friend John Cornish who had a 40 foot ladder. John was able to open and collect the pockets by standing on the top of the ladder for more than 16 hours. The largest of the two pockets was about 2 meter deep and contained fine calcite and natrolite specimens. About 40 flats of material were collected at this time. Perhaps the best piece from the pocket was a 45cm specimen with a 10cm rhombohedral golden brown calcite crystal that contains an 8cm movable bubble and is currently on display at the Rice Museum in Hillsboro, Oregon, USA. Little has come out in recent years, mostly because collectors have irritated the quarry owner and he does not permit collecting in the quarry.

These calcites that are loaded with sand from Rattlesnake Butte are dug from surface digs and very distinctive. In years past it was common to see them for sale in rocks shops. The locality is apparently on an Indian Reservation and access is much more restricted than it used to be. These crystals of sand included calcites, a bit similar to the very old classic ones from at Fontainebleau, France that look a bit like the Sidney Oprah house are probably the two best known localities for "sand" calcites.

Many people consider the calcites from this locality to be the best in the world and when you see the best from Elmwood you find it difficult to disagree with them. It used to be that the best British calcites were considered king although you really needed a good copper in calcite from Michigan if you wanted to cover your bases on Calcite. Then The calcites from Tennessee came along and the templates of mineralogical desirability shifted and the British calcites had to more over, at least a little. The Elmwood mine is a an underground zinc mine where Sphalerite was/is the main ore. During mining, pockets of Calcite, Sphalerite, Bartie and Fluorite were encountered, some of which were world class specimens. Tens of thousands of specimens were produced and though the miners were probably responsible for collecting and selling most of them on the side, though at times the mine had deals with dealers to mine the specimens and on occasion had its own miners collected the specimens and held auctions to sell them. I think the best years of specimen production were in the 1970s, 80s, & 90s.

Muddy Creek is a surface dig locality where Septarian nodules are collected by hand and at times times with heavy equipment. Hundreds of tons of these nodules have been collected for cutting and polishing into book ends, eggs, spheres and other lapidary items. The ones we see above have been cut and polished to take advantage of their frequently attractive interiors which are often lined with attractive little yellow calcite crystals. Though a good one is not shown here, occasionally hollow ones are encountered that have tan prismatic Baryte crystals in them, though they are rare and not nearly the quality of good Baryte from the Septarian nodules ones the Elk Creek area of South Dakota which are often a beautiful red gold color. As a little extra bonus, the calcite in these nodules from Muddy Creek fluoresce nicely under UV light as you can see in the top two images shown above.

These are pseudomorphs of Calcite after Ikaite. They are interesting and would be seen abundantly from many localities if they were not so ugly compared to most other calcite specimens. When these are found, they are usually in huge abundance, but it just doesn't pay usually to collect them. And remember the ones shown here are what the pretty ones look like.

The calcites from Shullsburg have been around for at least 50 years but are not widely known among collectors because the number of specimens that the mine has produced has not been very large. The are often distinctive because of the phantoms of Marcasite that grow inside the Calcite crystals.

Hi Rock,

Thank you for your efforts, but no, the first draft is not finished. I posted the comment below to you several days ago (after you'd written on the Calcite USA, Alabama to Montana thread) and have not seen the changes presented corrected. While I understand that these changes are small, for the article to be complete, contributors need to be acknowledged. Thank you,

John Cornish


Hi Rock,

Thank you for all of your efforts here at Mindat. I saw your post on Calcite, USA, Alabama to Montana and took a look...

You mention the Calcite replacements after Ikaite from Alaska (not celestite). These were collected by Dave ? (sorry, I can't remember his last name, now deceased). Rudy Tschernich of the Rice Museum would know his last name as Dave had been active here in Washington through the local FM and another group, the Northwest Micro Mineral Study Group. He had personally collected these.

These examples, and many others of this type from other World localities are currently being researched by a group out of Denmark.

As a last thought regarding this material, I would ask that you reconsider your statement... "More familiar examples of this type are those shown further down from Camp Verde, Arizona." ... Other than being a pseudo, they really are not similar.

Also, for Montana, I see that two of my photos have been captured and added to this thread, they are the 2 Gallatin photos where specimens are displayed for a show (in this case, for the Kitsap Gem and Mineral Society show held in 2009. I personally collected and own all of these specimens and would be thankful of the recognition.

For your post Calcite, USA, Nevada to Wyoming, I see that another photo of another personally collected specimen has been added to this thread, this one the 45 cm calcite from the Gopher Valley Quarry located just outside of Sheridan, Oregon. This is likely the best large calcite ever recovered from the basalts of Oregon. This is due not to its large size, though there appears to be none known as large or larger, but rather for the exceptional water bubble that is an inch wide and travels 3 inches within one of the major rhombic crystals. Several other calcites from this pocket additionally contained 2 or possibly 3 phase inclusions, though this was the most outstanding example. These crystals were recovered from the finest pocket of natrolite ever recovered from Oregon (R. Tschernich personal communication). More photos from this dig are presented in my personal photos here at Mindat if you've an interest.

Again, thank you for all of your efforts Rock! Take care and all the very best!

John,
Thanks for your email and the corrections and suggestions. I have reworded the text under the Alaska pseudomorph. I expressed my self very poorly. I meant that the Camp Verde glauberite pseudomorphs were similar in that they were calcite pseudomorphs and also formed in a find grained sediment/mud and were there in vast quantities as the Alaska pseudomorphs most likely were. Before I take the Under Construction heading off the second calcite part, Ill make sure you other concerns were also addressed.

John,
Would you consider writing a paragraph or two about the calcites from Gallatin and the Gopher Valley Quarry? Perhaps a bit about the geology, when you collected the specimens? How many were there and did others collect some too? Were these the best specimens? If not what was the best specimen, How big the crystals got? How many were collected. It is rare that we can get this information directly from the person who dug the best specimens. I have asked Rudy for some info on the glendonites and asked if he would consider looking at the localities that he knew about and writ up similar information. I hope he can find the time.

At the Iceland Spar Claim in New Mexico, optical grade calcite was produced (1.5 foot crystals near the border of the deposit). Two large crystals (25 and 30-40 tons) were found in the deposit 7x8x11 feet and 8x9x10 feet.

The Terlingua calcites are better known for their blue-white phosphorescence.

Your just full of surprises this morning. You wouldn't just happen to have some other goodies just lying around would you? They will all be welcome. I would like to include something about those giant New Mexican Iceland spar crystals. Could you point me to a reference on that? Is it it in the Giant Crystal project somewhere? Do you know the corresponding Mindat locality?

Your note refers to the sand calcite locality as Snake Butte. Any idea how that relates to Rattlesnake butte? Put your note in the article by the way.

Hi Rock,

Again, thank you, I appreciate your taking the time to help and to comment. For the last several hours, I've been scanning material as per your Gopher Valley request and will contact you with this information. I went a bit over-kill, but you'll have the whole story.

Regarding Rudy and the Gopher Valley Quarry, in the publication I'll be sending, he writes a wonderful little paper on this localities pyrites, the best in the State! He'd be able to comment on this better than I should you see the need.

And finally, Gallatin, let me know what you think of the material I'll be sending and I'll proceed from there as you request.

As a final Gopher Valley thought, please consider...

Rock,

I have some very nice calcite crystals in my collection from both Burnet and Travis County, Texas. Are you interested in pictures of these for this article. If so, let me know and I'll do some pictures for you to look at.

John, Ill look forward to the additional information on Gopher valley. Thanks. I have already added the image of the natrolite/calcite specimen and some of the information that was in the caption of that image.

Dave, As always you are unfailingly helpful and informative. When I get a bit of time, Ill add the locality and some of the information extracted from that interesting old American Mineralogist article?? Do you have the volume or the year and page number? I have a bound set till 1991 & loose after, that I keep on shelves in my home office.

Bill I can't honestly say for sure if I would use pictures of your specimens from Burnet and Travis county or not till I saw them. If the specimens are better or as good than those already shown on in the Mindat Galleries, the answer is almost certainly yes, I would use them. I am certain that you must have in your collection a number of specimens that are better than those already in the mindat gallery. It would be nice to have them all in the mindat gallery where we could all see them, but in practical terms, there is only so much we can do. In the past I took mostly pictures of good specimens that were in museums and other collections that were not in my own. After all, I already had the specimens in my collection, why bother to take pictures of them. You can go and look at those any time, right? Well, its funny how our viewpoints change with time.

Rock,

The Millington calcite is photo that you may wish to consider for inclusion in the article is 96685. The incorrect photos are: 233527 - This specimen noted as Prospect Park is from the McBride Ave and Browertown Road Sewer Pumping Station in Woodland Park (formerly West Paterson). 92789 - This specimen is shown twice under Fanwood and Chimney Rock. It is from Fanwood. 111156 and 269665 are incorrectly listed by their owners. Both are from the former Houdaille quarry in Little Falls, not Montclair. Most of the locals note this material as "Montclair". It is a similar error to those that say the Chimney Rock quarry in Bound Brook. The Chimney Rock quarry quarry is actually in Bridgewater; the Bound Brook runs adjacent to the quarry. The town of Bound Brook is about a mile away.

With respect to the the three locations I mentioned in my initial message, (Montclair, Houdaille quarry, Little Falls and Bergen Hill), all were before my time so I'd be reaching to write anything. Bergen Hill and Montclair were from the late 1800s-1920s. The mineralization in the intrusive diabase at Bergen Hill occurred in veins that transected the Palisades Sill. There is no basalt. Although I collected at the Houdaille quarry, it was many years after the quarry closed and all I found was quartz casts after glauberite. The best material (stilbites and calcite) was collected in an area which is now a parking lot.
