Anadalusite in Sericite Shist
stock #18-AX 35-159
Cargo Muchacho Mountains, Imperial County
5.7 x 3.9 x 3.1 CM (cabinet)
Late Summer 2018
Something a bit unusual, the main Andalusite crystal is well-formed and over 3.5 CM across. Nice overall composition, the biggest Andalusite is quite well exposed from the Schist. Ex S. Alverson collection, this was collected in 1980, but not at any of the noted mines, just a small prospect. Microscopic exam finds many Hematite crystals and one Kyanite in the matrix as well. A fine, less common California specimen and a nice prismatic crystal of Andalusite.
