Oloi-Yarakvaam Terrane, Verkhoyansk Kolyma, Eurasian Plate (original) (raw)

Description: complex intergrowths of three types with native lead, possibly resulting from breakdown of solid solutions. In the intergrowths, anyuiite typically forms platy aggregates ranging from 1-50 μm across and 100-900 μm long, and prismatic crystals 50 x 100 μm. Associated minerals include ilmenite, titanian magnetite, chrome spinel, hematite, pyrite, chalcopyrite, and apatite. Oxidizes after 1.5-2 days, becoming dull lead-gray.
