MD-206836 - Stokesite, Stannomicrolite, Albite - - Archived Urucum mine (Tim mine; Córrego do Urucum pegmatite), Galiléia, Doce valley, Minas Gerais, Southeast Region, Brazil miniature, 4.1 x 3.3 x 3.0 cm.
4.1 x 3.3 x 3.0 cm. An excellent example of both of these species from an important find brought to market by Carlos Barbosa before he passed away, in the late 1990s. I recall when these came out, it was almost impossible to find even a single specimen with both the Stokesite (the sharp white crystals) and the stannomicrolite (brown crystal) on the same specimen - let alone in close proximity. This is an aesthetic representation of both species, in unusual association. Both crystals are of unusually good size for the find, as well. Ex. Dr. Mark Feinglos Collection.
MD-222490 - Stannomicrolite, Stokesite - - Archived Urucum mine (Tim mine; Córrego do Urucum pegmatite), Galiléia, Doce valley, Minas Gerais, Southeast Region, Brazil thumbnail, 1.2 x 1.1 x 0.9 cm.
1.2 x 1.1 x 0.9 cm. An excellent thumbnail of rarities from the Corrego do Urucum Pegmatite of Brazil. A rich dusting of yellowish-brown stannomicrolite microcrystals coats glassy stokesite crystals. Stannomicrolite (a hydroxide) is the tin-rich member of the microlite subgroup of the pyrochlore group of minerals and is known from only three localities worldwide. Stokesite is a very rare calcium, tin silicate. Older material.
rar09-mf10 - Stokesite with Stannomicrolite on Albite - $ 200 Urucum Mine, Galileia, Minas Gerais, Brazil miniature, 4.1 x 3.3 x 3.0 cm
ex. Dr. Mark Feinglos Collection An excellent example of both of these species from an important find brought to market by Carlos Barbosa before he passed away , in the late 1990s. I recall when these came out, it was almost impossible to find even a single specimen with both the Stokesite (the sharp white xls) and the stannomicrolite (brown crystal) on the same specimen - let alone in close proximity. This is an aesthetic representation of both species, in unusual association, on a well trimmed matrix of bladed albite so it displays nicely. Both crystals are of unusually good size for the find, as well. All Content and Design ©1996-2010 The ArkenstonePowered by http://mineralwebsites.comBy-species Galleries | ||||||
