“The only observed occurrence of chambersite is from Storage W ell No.1 of the Texas Natural Gasoline Corporation on the northwest flank ofBarber's Hill salt dome, Mont Belvieu, Chambers County, Texas. The mineral is present in brine returns from the well, and although accurate
information as to the depth of the occurrence is not available, driller's logs indicate an origin in the main salt mass at a depth between 2,32O and 2,72O level below sea level.”

A 12 mm xl from Barbers Hill is a keeper. Abundant below 5 mm, common up to 8 mm, uncommon over 10 mm. I’ve had several in 10+ range. About 20 years ago I sold my largest which I believe was 12 possibly 13 for $50. At that time didn’t consider as the largest, only that I could get $50. Have heard reports of 15 mm, however, nothing over 12 confirmed.

No divers in the salt dome! I’ve heard reports of divers collecting at bottom of a 70 foot deep brine pit, also fiction. Collecting 5-10 mm xls., in diving gear at bottom of 70 foot pit?

Dr. Pough collected many at Venice Dome in 1969 (confirmed by U. of New Orleans) from a swamp that was later destroyed by a hurricane, don’t believe he was ever at Barbers Hill. There are no swamps at Barbers Hill.

Standard collecting technique used by Art Smith (personal communication) and others. There was a large flat area of solidified brine material (anhydrite?). Art indicated that the brine had been pumped across this large area and evaporated/solidified. Collectors crawled on hands and knees on the surface. You would feel the presence of a crystal due to the sharp points on your hands or knees. Some of the dry material was also used to surface some local driveways, some Chambersite xls. were found imbedded in vehicle tires. I was only able to view the collecting area through a high chain link fence with large “Keep Out” signs. I over the years I was able to acquire several small lots from collectors.]]> Harold (Hal) Prior Best Minerals C Thu, 11 Apr 2013 14:48:37 +0000 http://www.mindat.org/forum.php?read,69,129517,290985#msg-290985 http://www.mindat.org/forum.php?read,69,129517,290985#msg-290985 Van King Best Minerals C Thu, 11 Apr 2013 12:32:49 +0000 http://www.mindat.org/forum.php?read,69,129517,290969#msg-290969 http://www.mindat.org/forum.php?read,69,129517,290969#msg-290969 I lived for 30 years about 25 miles from the Barbers Hill Locale. Will provide some additional info for the Barbers Hill Chambersite in a few days (need to locate some more info). Barbers Hill is located near Mont Belvieu, Texas. A 1985 explosion at one of the plants threatened the entire salt dome (on which the city was built), which had in recent years been used to store liquid propane gas, and led to a series of efforts by townspeople to force the petrochemical industries to buy out the homes in the immediate vicinity of their plants. By 1990 some 200 families had been bought out by a dozen petrochemical corporations. With the aid of these local industries the community was rebuilt on I-10 two miles east of its 1985 location. The entire area is now fenced (since 1990) off with armed guards as of my last visit to the locale. First found in 1957 in brine returns from a gas storage well in the Barber's Hill salt dome, Chambers County, Texas. Many interesting collecting stories were related to me by my friend Art Smith. .....Hal Prior]]> Harold (Hal) Prior Best Minerals C Thu, 11 Apr 2013 02:25:42 +0000 http://www.mindat.org/forum.php?read,69,129517,290959#msg-290959 http://www.mindat.org/forum.php?read,69,129517,290959#msg-290959

Chambersite, 1 cm, Nova Scotia	© R. Van Dommelen

The Pugwash Salt Mine in Nova Scotia produced a one time find many years ago (1990s?) of fine chambersite crystals. My understanding is that the find was mde by the mine engineer during a mapping exercise. I don't know how many crystals were found; I remember seeing a tray with about 10 or so tiny crystals. We have tried tracking them down since then without luck. However one amazing crystal, pictured above, is in the Fundy Geological Museum (not on display). It is a full 1cm on an edge with smooth faces and simple form.]]> Ronnie Van Dommelen (2) Best Minerals C Thu, 11 Apr 2013 00:57:06 +0000 http://www.mindat.org/forum.php?read,69,279137,279137#msg-279137 http://www.mindat.org/forum.php?read,69,279137,279137#msg-279137 Best Minerals and here for Tourmaline group minerals, here for Chromium-dravite, here for Chromo-alumino-povondraite, here for Dravite, here for Elbaite, Afghanistan to Nigeria, here for Elbaite, Pakistan to Zambia here for Feruvite, here for Fluor Buergerite here for Fluor-dravite, here for Fluor-elbaite, here for Fluor-feruvite, here for Fluor-liddicoatite, here for Fluor-schorl, here for Foitite, here for Liddicoatite, here for Luinaite-(OH), here for Magnesiofoitite, here for Olenite, here for Oxy-dravite, here for Oxy-rossmanite, here for Oxy-schorl, here for Povondraite, here for Rossmanite, here for Schorl, here for Tsilaisite and here for Vanadium-dravite.

Does this answer any of your concerns.

Right now, the Chalcopyrite article is really in terrible shape because it is under construction. I have made a rough selection of chalcopyrite images and just "thrown" them into the thread (construction space) and they look awful. There is a lot of fine tuning and arranging that needs to be completed before the article will begin to look reasonable. Undoubtedly some of the images now in the construction space will be thrown out and possibly others added. Comments will be added about many of the others. As this process works its way through to completion, hopefully others like yourself will chime in with useful and interesting comments, observations about the images pictured and the localities they come from or even upload better images that we can use in the article.]]> Rock Currier Best Minerals C Mon, 08 Oct 2012 21:12:30 +0000 http://www.mindat.org/forum.php?read,69,273202,273276#msg-273276 http://www.mindat.org/forum.php?read,69,273202,273276#msg-273276 Erik Vercammen Best Minerals C Mon, 08 Oct 2012 19:23:00 +0000 http://www.mindat.org/forum.php?read,69,273202,273269#msg-273269 http://www.mindat.org/forum.php?read,69,273202,273269#msg-273269 Kelly Nash Best Minerals C Mon, 08 Oct 2012 18:52:56 +0000 http://www.mindat.org/forum.php?read,69,273202,273232#msg-273232 http://www.mindat.org/forum.php?read,69,273202,273232#msg-273232

I want to bring up something that is not a real big deal, but slightly problematic, that hopefully can be easily remedied at some point. My photos, which include a few here (e.g the second chalcopyrite with galena from Madan, Bulgaria and the second to last specimen from Sweetwater Mine, MO) are "Creative Commons with attribution" on the original entries. As I understand it, all that means is that they can be reproduced as long as my name is credited as the photographer. I notice the copyrighted photos have names attached (most of the time anyway), but these just have a copyright symbol with no name attached. They are not copyrighted.

Indeed the photo pages themselves have no name, they just indicate "Creative Commons Some rights reserved". So I occasionally get emails asking if somebody can reproduce my picture in their club newsletter or whatever, when really, they should be able to easily find my name, attach it to the photo, and spread it around as much as they want without even asking me.

Like I say, not a big deal, and I don't know if this is easily remedied for the "Best of" pages. But if these Creative Commons options are available and have any meaning, they should be treated as they are intended, just like copyrights are.

Chalcopyrite

Chalcopyrite from the Greek meaning copper or brass and pyrite from the Greek meaning fire stone (Oxford 2nt) for its illusion to the ability to strike sparks. Chalcopyrite is the most abundant and wide spread ore of copper and in fact is the most abundant copper mineral. It occurs in a large variety of geological settings. The top two images above are from hydrothermal veins in base metal mines and the one below showing chalcopyrite's botryoidal (blister copper) form is from basalt in a trap rock quarry. Chalcopyrite has been known from ancient times and has been described in most if not all of all the ancient/old mineral books including Agricola.s, De Rey Metalica in 1556. The Handbook of Mineralpgy v.1 sites crystals up to 10 cm.

Chalcopyrite along with pyrite is commonly mistaken for gold and is sometimes referred to as fools gold. It is softer than pyrite and can easily be scratched with a knife. It is easily decomposed by nitric acid and forms a blue solution which can be made a dark blue by the addition of ammonia. Chalcopyrite is tetragonal but for many years was thought to be cubic till accurate measurements were made in 1822. The crystals are commonly tetragonal looking and usually sharp and distinct when small, but larger crystals become curved and striated and of irregular shape. Larger crystals have faces that commonly marked with triangular striations. Chalcopyrite is not uncommonly seen as coating other minerals like tetrahedrite, and sphalerite and forms oriented overgrowths on sphalerite and galena. Chalcopyrite crystals are commonly found growing with crystals of galena and sphalerite as you will note in the images below.

Chalcopyrite is is easily oxidized and this can be see from the very many images below where the chalcopyrite in the specimens is not brilliant and shiny. Sometimes the surfaces of the crystals are almost black looking or they have been altered to other minerals sometimes giving them striking iridescent colors. This iridescence is often due to the chalcopyrite altering to other minerals. Blue and purple colors predominate although reds and greens are not uncommon. Sometimes this iridescent coloration is not natural, but the result of specimens dipped in solutions of various acids to create the iridescent colors to make them more salable. Each year, tons of massive ore rich in chalcopyrite is broken down into small chunks and acid treated to produce the rainbow colors. These are then sold to tourists and it is the rare beginning collector that has not added one or more of these to their collection. Usually the acid used is fairly concentrated sulfuric acid sometimes with phosphoric acid adid. The people who do this work have their own proprietary formulas for these acid solutions.

Which localities produce the best specimens? I'm not sure any locality has a lock on this distinction. At any rate, the purpose of the best minerals articles is not to tell you which is the best, but to show you enough good specimens from all the good localities that we can find and let you make up your own mind as to which locality is best. I would however, particularly draw your attention to those from Australia, Bulgaria, Peru, Romania. It is probable that images of the best chalcopyrites from these localities have yet to be uploaded to our database.

This specimen is not remarkable except as an example of the great abundance of similar specimens that were produced from the mines in the Tri-state district. Many thousands of specimens were produced and sold cheaply to rock shops all of the USA and the world. The ultimate fate of most of them it that they sit around for a while and get dirty, then they get damaged and or broken and finally thrown away. Large quantities of similar specimens have been collected from other localities as well.

I was also thinking that the white corundum crystals might be pseudomorphs, but

a) I guess, based on the appearance of the crystals, that they have weathered free from the host rocks ( this assumption is pure guesswork from my side) - thus indicating that the crystals have a higher weathering resistance than feldspar.

b) I cannot find any evidence of any regional retrograde metamorphosis in any of the literature references. EDIT: Not entirely true- Occhipinti et. al mentions sillimanite completely replaced by sericite in the Mumba Metapelite and garnets partly or fully replaced by chlorite

But again, this is guesswork from my side and a simple hardness test may prove my guesses completely wrong.


Regarding the locality, I've put all of them into one Gascoyne entry, accounting for the uncertainty of the localities. Any feedback on the text will be appreciated.

You will need to upload the photo to the database for me to be able to use it in the article.
