Crystallized minerals

Photo from 2 different viewpoints. Erythrite: Cobalt ore. Chemical formula: Co3[AsO4]2.8H2O. Crystal system: monoclinic. Annabergite or nickel bloom. Arsenate group. System: Monoclinic. Density: d3.1. Chemical formula: Ni3[AsO4]2.2H2O. Appears as aggregates of lamellar crystals of apple-green color. This is a rare product of the alteration of nickel-bearing sulfides.

Presence on the pink calcite of Arsenopyrite from the sulfide family, a major mineral of arsenic, iron, and sulfur. Found in medium to high-temperature hydrothermal veins. Assembly of skutterudite, rammelsbergite, nickelite, chalcopyrite, Hematite.
