We explored more of the vein with the gray crystals in situ.
The richer mineralized vein is rather thin (about 8 inches) in marble. The vein zones with gray crystals has phlogpite, pink spinels and rarely a chondrodite crystal. I observed what might be serpentine and possibly also anhedral blue green diopside.
I consider the gray crsytals to be yet another form of diopside. Goldschmidts' atlas of crystal shapes shows monocline pyroxenes crystal shapes like the ones found on the outcrops. I will post pictures.
The acidic effect of decomposing forest debris leaches and etches the marble exposing the embedded crystals. None of the free standing subhedral crystals can be found one foot and more below the surface.

The greasy feeling on the diopside is possibly a talc weathering. The talc will easily be washed away with cleaning.
Documents of the Assembly of the State of New York, Volume 23 By New York (State). Legislature. Assembly, page 315 lists an alteration series of diopside over optional talc to serpentine.

Some crystals are a bit translucent.

The fresh cleavage faces are at times brown, glossy stepped, others have some green tint.

I will be back with more

They have a sharp edge angle and pattern similar to titanite.
I hope this helps in identifying these very interesting crystals!
THANKS Glenn for an amazing afternoon, and some great finds!

I found the crystal similar to this habit: [www.mindat.org]
Do you have any broken crystals where you can see cleavage and cleavage angle?

Hi Phil, Iv'e been doing a little reading up on Pyroxenes and Amphiboles. Pyroxenes are square at a cross section, 87 and 93 degrees with shinny cleavage and Amphiboles have diamond shape cross sections and corner angles at 124 and 56 degrees. These crystals some of them are shinny inside and others are not and I can't find any cleavage angle. Then you have one altering to the other so its really hard figuring out whats what but from everything I've found so far the Pyroxenes are all ways between the Gneiss and the marble and the association of minerals are the same. Diopside, Scapolite Titanite, Pargasite and augite. The other group is Spinel, Serpintine, Uvite, and Chondrodite, these crystals I'm finding are in the latter group and directly in the marble. Now the Amphiboles I'll find in the marble (Tremolite,Edenite) with no contact of country rock but never with Spinel or Chondrodite . Of coarse this is just my findings here but there are a good twenty different locations and every fifty feet or so things change. The fluorescent minerals are a whole different animal. I'll send some off to get tested. Thanks for your imput and I'll work on my crystal structures for better future ID's]]> Glenn Rhein Scrapbook Fri, 03 May 2013 22:34:11 +0000 http://www.mindat.org/forum.php?read,17,199026,292772#msg-292772 http://www.mindat.org/forum.php?read,17,199026,292772#msg-292772
The photo of Glenn's display case at the NY-NJ show that he is referring to can be seen in the link below:
Glenn's Exhibit at the NY-NJ Show

Scroll down to the middle of the page. There is also one of the large scapolite/diopside crystals that Glenn placed there for people to be able to touch. I am not so happy with the image quality - lighting and transparent background made photography challenging.

Also, here is a photo of myself and Glenn posing in front of my booth at the NY-NJ show with the video we produced playing right beneath us.

When you going to get down this way again Wayne ?

Matt, you are not alone suggesting a pyroxene but I'm thinking Uvite or maybe even Vesuvianite. I'm going to get it tested]]> Glenn Rhein Scrapbook Tue, 30 Apr 2013 23:15:21 +0000 http://www.mindat.org/forum.php?read,17,199026,292646#msg-292646 http://www.mindat.org/forum.php?read,17,199026,292646#msg-292646

Here's a 1/4 inch spinel with great luster, a lot of these also and a picture of matrix they are in.

The crystals, especially in the bottom photo, look like forsterite (Mg olivine end member) crystals. If they have a greasy feel then they are altered, perhaps partially (i.e. core could be olivine) to serpentine and perhaps talc: Serpentine pseudomorph after forsterite.

Serpentine does not occur as euhedral crystals (though not sure if euhedral crystals can be seen with electron microscopes?).

Nice minerals, the red spinels are especially neat!

I was out last night looking for those deep red spinels and came up with these guys. I think they might be Serpentine crystals. They feel a bit greasy and the matrix is Spinel,Serpentine and marble.[attachment 45065 DSCN6398.JPG][attachment 45066 DSCN6397.JPG][attachment 45067 DSCN6401.JPG]

A New Mineral Discovery in Amity, NY, with Glenn Rhein

I want to publicly thank Glenn for his cooperation and coordination in getting this video out, and for bringing this deposit back on the map. We need more people like Glenn!

Any comments or suggestions will be appreciated. Perhaps if there is interest we will make this into a longer video with the extra footage, and if more amazing finds are discovered we'll produce a sequel.
