Amesite : Mg2Al[(OH)4|AlSiO5] | |
|
Cerro Sapo, Ayopaya Province, Cochabamba Department, Bolivia Six-fold sector twinning is responsible for the creation of this distinctive field of stars made up of amesite crystal terminations. The specimen was acquired in Bolivia by Alfredo Petrov from a 1,000 year old pre-Inca sodalite mine. These crystals occur in shallow vugs in a sodalite matrix from an ankerite-sodalite-barite carbonatite dike. ... Mindat.org Photo of the Day - 1st Feb 2006 |
