Jagueite

Comments: Polished section (oil-immersion, plain polarized on left, cross-polarized on right) showing lobate grains of chrisstanleyite (Chr), replaced by jaguéite (Jag), with tiemannite (Tie). The jaguéite twinning is evident by banding in both images.
Location: El Chire prospect, Los Llantenes District of La Rioja Province, Argentina.. Scale: Picture size 150 µm.
