Calcium Arsenate Hydrate II crystals from the Clara Mine, Black Forest, Germany– miniature specimen as unique piece
This micromount specimen features Calcium Arsenate Hydrate II on a light-colored matrix from the world-famous Clara Mine in Germany's Black Forest region. The specimen consists of transparent to translucent crystal aggregates with a vitreous luster that are attractively developed on the matrix. The crystals are clearly visible and give the piece an appealing appearance despite its small size. Due to the rarity of this still unnamed mineral, the specimen possesses both scientific significance and collector appeal.
Geology & Origin
Calcium Arsenate Hydrate II is a rare secondary arsenate phase formed under the complex oxidation conditions of arsenic-bearing ore deposits. The Clara Mine is one of Europe's most important mineral localities and is renowned for its exceptional diversity of rare arsenates, sulfates and other secondary minerals. Numerous rare and scientifically important mineral occurrences have been discovered or studied there. Unnamed mineral phases such as this document the complex geochemical processes within the deposit and are particularly sought after by specialized micromount collectors.
