Carlsbad twins were first described from Karlovy Vary (Carlsbad), Bohemia, Czech Rep. Baveno twins from Baveno, Italy.
What about manebach twins? Is the word manebach a locality, a latin translation...?

I have a question for you. This is the best mineral site for collectors but there is only one thing that would be nice. A section for specific minerals that collectors are looking for that are hard to find. With the thousand of users on the web there is a wealth of knowledge of where to acquire a specimen. I’m looking for a mineral from a specific location but with goggling and surfing I can check out only a small percent of the web. Someone out there might have come across it at one time. Collectors helping collectors find specimens. This would be an info topic, not a selling page. That is what the auction is for. I know there are pros and cons about this. What do you think?

Thanks, Keith]]> Keith Williamson General Sun, 29 Nov 2009 05:52:27 +0000 http://www.mindat.org/forum.php?read,6,161639,161639#msg-161639 http://www.mindat.org/forum.php?read,6,161639,161639#msg-161639

Several such cases have already cropped up in other countries. Unless a mine is located on land politically controlled by a town, it might be best to put "x km SSW of Abcd Town" in the description box and leave the town name out of the geographic heirarchy string.
However this will require some rearranging at localities such as Cobalt and Bancroft, Ontario and I am sure numerous other places.
An alternate approach could be the nearest town with emphasis on coordinates. Example: Canada, Ontario, Wilberforce, Cardiff Mine, xxxN, xxxW. That way one doesn't have to worry about geographic boundaries. If the coordinates are not known then the title would simply be country, district or province, nearest town, mine, ?N, ?W. Eliminating as many geographic boundaries as possible would greatly simplify things and avoid many of the problems associated with changes in boundaries over time. Using coordinates would also be far more accurate than any other method. With access to google earth and other databases there is really no reason why coordinates cannot be found that are likely to be just as, if not more accurate than geographic names. If you know it is "x km SSW from Abcd Town" then you can also find the coordinates.]]> Reiner Mielke General Fri, 27 Nov 2009 14:35:01 +0000 http://www.mindat.org/forum.php?read,6,161439,161439#msg-161439 http://www.mindat.org/forum.php?read,6,161439,161439#msg-161439

I have created the MinDat.org group on LinkedIn.

For the ones who do not know it, this is a social network with a different purpose than FB's. It is used to link people in a professional way.
And this is why I decided to create it there, as well.

Also, does anyone know of any other mineral that exhibits botryoidalism formed in a serpentinite matrix besides secondary deposits of quartz?
Thanks.

(edit) The lack of replys is encouraging:)...I suppose serpentines are known to be found in the botryoidal...but thier softness gives them away.]]> Ezekiel Hughes General Mon, 23 Nov 2009 02:49:28 +0000 http://www.mindat.org/forum.php?read,6,161061,161061#msg-161061 http://www.mindat.org/forum.php?read,6,161061,161061#msg-161061

According to your experiences and knowledges, what will be the definition of a "world class mineral"?

When i am talking about, i am not talking about one specimen like a museum specimen but much more like a find of one mineral somewhere that can be consider like a world class mineral.

I only have one example in mind, the famous dolomite from Eugui in Spain because of the size, the clearness and the architecture of many specimens.

Does any one can give somes examples of what he think to be a world class mineral?

Thanks all for your answers

In the last years I have realized together with the Dr. Joan Viñals, a study on the paragénesis and the mineral associations in the "Mina Eureka", La torre de Cabdella, Lleida, Spain. During this work we have found new mineral species in this deposit.

I have published a new article in my blog.

I recently purchased some pyrite beads from China. Roughly 100 strands of different sizes and shapes with many of them having small pockets or vugs. Many of the pockets were coated or filled with a mercury-like metallic substance on the beads along with a white powder. I have played with and handled a lot of mercury over the years, so I am well acquainted with it. The white powder is apparently either aluminum oxide or talc used in polishing the beads.

I assumed the mercury was used as part of the polishing process.

I sent them back and the manufacture had them tested at a lab in Hong Kong. They tested them by atomic absorption and said there was absolutely no mercury on the beads. The amount of samples test was high, several hundred from a one ton pallet of beads.

My question is what compound did I confuse as liquid mercury on the beads?]]> Rick Dalrymple General Mon, 16 Nov 2009 23:41:54 +0000 http://www.mindat.org/forum.php?read,6,160241,160241#msg-160241 http://www.mindat.org/forum.php?read,6,160241,160241#msg-160241 Price is only £16 including refreshments and lunch.

Art's amazing mineral collection is world-class but his Texas Locality Index is still the most comprehensive compilation of its type in the State of Texas and will probably be his legacy. Many weekend "rock lickers" just like me caught the fever by reading his detailed descriptions of the salt domes, pegmatites, deserts, piney woods, coastal flats and prairie grasslands that defined the mineral collecting sites in Texas. It was always a work in progress and no rockshop, University Geology library or collector's backpack was complete without a copy. I can look across my desk right now and see my own mud-stained, dog-eared copy peeking through the flap of my backpack, waiting to go back out into the field.

I'm going to miss you, buddy. I will always cherish the memory of what turned out to be our only collecting trip together into the Llano Uplift of Texas during a fortuitous period of remission in Art's illness.

For those of you in the Houston area, and those who feel like making the trip, there will be a memorial service at 2 PM on Monday, November 16th at the Southwest Calvary Baptist Church, 12910 W Bellfort Ave, Houston, TX.

I was looking at Larry's Mineral Trading List website, and had a blast reading through people's specialties. It's amazing how many there are! When I started collecting, I decided that hey, I'm from Arizona and copper is a big thing here.. Why don't I collect Arizona copper minerals? Little did I know how collectible they are!!! So with as much detail as you'd like, I'd love to hear about people's "specialties."

My specialty: I love Arizona minerals, especially copper-leads, pieces with historical significance, and rare Tiger pieces.

Please share! It's enlightening to see what people really go for. Then maybe we can tally them up and see what's really popular.. And who's really weird! :)

AA 469 xx- Backside of an aragonite specimen from Spania Dolina (?).
It is collected before 1870 (pre-previous owner died that year)- but my question is WHAT do the numbers stand for. (137/ 40484/ 280 )?
One could be a price, one “size/weight” and the third…..
I would especially appreciate if anyone has any knowledge of this kind of label. Slovakian/ Czech experts!!
469 show of course the 2 crystals (left is damaged)- roughly 30 mm tall
