Mineral
Conicalcita
CaCu(AsO₄)(OH) · Arseniatos
Conichalcite is a copper and calcium hydroxyarsenate.
At Fiñana it occurs as globular coatings of intensely saturated green with a matte appearance. The habit is botryoidal to globular on surfaces. In that locality, continuous, well-developed carpets are uncommon.
At Fiñana, pieces are usually small, often about 2×2 cm or less. There, coatings often show breaks, bald patches or chips. Consequently, continuous, unbroken development is an exception in that locality.
Etymology
Greek roots κονία ('konis', dust) and χαλκος ('chalkos', copper), chosen by Breithaupt and Fritzsche to reflect its physical appearance and metallic content.
