Amarantite

specimen number:
2133088

location:
Sierra Gorda, Antofagasta, Chile

description:
Red crystalline and massive amarantite across matrix. Good example for the species.

Amarantite is a hydrated iron sulfate mineral that forms in the oxidized zones of sulfide ore deposits. It develops as thin tabular crystals or crusts and is typically red to pink in color due to the presence of iron. The mineral forms through the weathering of iron sulfide minerals such as pyrite in arid environments. Amarantite is often associated with other sulfate minerals and is of interest to collectors for its bright color and delicate crystal form.
