Have found a AmScope SM-1TSZ-144-9m microscope on ebay and want to hear you opinion
on the microscope, and especially the small 9mp camera?
How about quality of the photos? Can you attach a photo shot with that camera?
How about quality of the microscope? Is there any complications if shift over to ex. a nikon camera?

I'm wondering if anyone else is interested in the Otamo Siikainen locality? I live 10km from this dolomite quarry and collect there a lot and publish photo's from the site. (http://www.flickr.com/photos/finnchaga/sets/72157632821144102/)

I have exchanged emails with the "locality experts" F. Sandström and M. Kurhila, both of who are unfortunately not anymore actively concerned with this locality, as I understand. I'm aiming at bringing the Otamo locality up-to-date as to species found and photos as well.

Currently, there are perhaps 2-3 minerals not published for the locality; one is galena as a certainty and some other of my samples are currently awaiting 2nd analysis by the Geological Survey of Finland. Another suspected species in sphalerite, I'll be posting an analysis help request for this mineral.

Please let me know if anyone is interested in discussing this locality, exchanging ideas, photos etc. An organized trip there is scheduled for June 15th and the contact person for booking is Pekka Ruoho. I myself am currently arranging the specifics for safety & rules during the visit.]]> Joel Dyer General Thu, 16 May 2013 04:58:19 +0000 http://www.mindat.org/forum.php?read,6,293968,293968#msg-293968 http://www.mindat.org/forum.php?read,6,293968,293968#msg-293968 KSL NEWS

I checked under "Grootberg Pass, Grootberg Mountains, Khorixas District, Kunene Region, Namibia".
There are only like 11 photos there and the above mention one not? why is it?
Thanks Herman]]> Herman Du Plessis General Sun, 19 May 2013 15:44:18 +0000 http://www.mindat.org/forum.php?read,6,293651,293651#msg-293651 http://www.mindat.org/forum.php?read,6,293651,293651#msg-293651 Exactly 50 years ago, on 11 May 1963, the very first meeting of the MKA (Mineralogische Kring Antwerpen) took place in Antwerp.
After more than 1000 (!!!) meetings and various other activities, it is still alive and kicking, I would say more than ever (with around 400 members, about 250 pages of Geonieuws magazine yearly, its splendid website (www.minerant.org), numerous presentations and other activities, the yearly mineral show Minerant, its huge library and interesting exhibitions) !
Special congratulations to Paul Tambuyser and Paul Van hee, the only actual MKA-members who were present from that very first meeting.

I have 4 days to and from Paris for my free time.
Could anyone tell me where I can go to collect some samples?
The samples can be any minerals and rocks really.
Since I am not familiar with Europe, accessibility to the localities is more important.

I appreciate if you can point some diretions where to go.

Thank you.]]> Yoshihiro Ikeda General Sun, 12 May 2013 22:21:27 +0000 http://www.mindat.org/forum.php?read,6,293305,293305#msg-293305 http://www.mindat.org/forum.php?read,6,293305,293305#msg-293305

The first is the discovery by archeologists of "mysterious orbs" in a temple in Mexico. A photo of the "orbs" is about 1/3 of the way down the page. Possibly an ancient Mexican's collection of pyrite concretions?

[gizmodo.com]

Second is the announcement of the discovery of the "first" fragments from the Tunguska explosion in Siberia (1908). These were collected from a stream 20 some years ago and, despite the claims, look more like ironstone concretions:

1. To the gentleman that was concerned that the Au and Te from Cripple Creek did not make it.
Actually it did, they made Colorado Gold as statewide inclusive(AMT #29 as it appears in the book.
As for his comment that Cripple Creek is more prominent than Twin Creeks NV (AMT #37) and
Eden Mills (AMT #6), I think not, Of a Carlin-type Gold deposit #37 is the best. And as a skarn deposit
#6 is our Jefferies Quarry.
2. About those snarky comments from Justin with absolutely no vowels in his last name, we all have our
"why this did not make it". We all have our favorites that did not make it.
Here's mine:
1. Spruce Pine District (Was listed as an amethyst locality on the voting list, amethyst is the only thing not found there)
2. Hallalulah Jct. (my opinion beats the snot out of Denny Mtn)
3. Colorado Rhodochrosites inclusive (like they did for Southern CA pegmatites).
4. New Jersey Basalt Traps
5. The William Wise Mine New Hampshire

These are mine, I would love to get imput on all your favorites .
As for the borates of California, I conversed with Janet Clifford (co-author of the Red Beryl (AMT #27) and
Golden Beryl (AMT #32).
THEY MELT!
It's hard to be a "treasure" when it melts when it gets wet.
I will query that Scovil dude about that at the CMS show later today about that

3. I should state for the record that that not only was there was limited space in the book, also the venue had problems with showcase space and their still trying to cram the DVD down to something reasonable.
Still the AMT project was a monumental endeavor that will never be repeated, and all those involved are to be commended.]]> Ronald Ruschman General Mon, 06 May 2013 20:59:31 +0000 http://www.mindat.org/forum.php?read,6,293018,293018#msg-293018 http://www.mindat.org/forum.php?read,6,293018,293018#msg-293018 gary green General Sat, 04 May 2013 06:30:20 +0000 http://www.mindat.org/forum.php?read,6,292977,292977#msg-292977 http://www.mindat.org/forum.php?read,6,292977,292977#msg-292977

There are many good ways to do this, but the easiest are sponsoring pages - [www.mindat.org] or just simply making a donation - [www.mindat.org]
