What is drusy


#1

Hi Marty

   uvarovite is a green garnet carpet of crystals-kamarararite is
a beautiful magenta to plum color and I have even found some gem
quality intense tan drusy (which was not quartz) whose name I
forget 

Uvarovite Ca3Cr2(SiO4)3 is a rare chromium garnet named after Count
S.S. Uvarov (1765-1855) Russia. Crystals found in Magog, Quebec;
Bissersk, Ural Mountains, USSR; Outokumpo, Finland. Nice druses have
been found at Riddle, Grant County, Oregon; Red Lodge Mine, Yoba
County, California.

Chlorite (Mg,Fe, Al)6(OH)8[(Al,Si)4O10] which are a basic iron,
magnesium, aluminum silicate.Kaemmererite is one of the Chlorite
group, that is colored rich violet because of the presence of
chromium instead of aluminum. (see Minerology by Sinkankas) It can
be found in Low’s Mine and Wood’s Chrome Mine, Lancaster Co.,
Pennsylvania; and apparently in some chromite mines in California
and Turkey.
