Chemical Formula: CaCO3

Chemical Name: Calcium Carbonate

Mineral Class: Carbonate

Mineral Notes: Calcite is one of the commonest minerals, being the main constituent of limestone. Calcite is often fluorescent, a small amount of Managnese is enough to make it glow red under UV light. The mineral will bubble in acid distinguishing it from many similar species, even other carbonates which do not dissolve so easily in cold acids.

Description: A matrix very richly studded with well-formed crystals of Pyrite and Chalcopyrite on which sits a thick blanket of Quartz columns. The ends of these are encased by extremely lustrous Calcite. The mineral is composed of tiny plates fused into rounded aggreagates on each of the Quartz points. A very easthetic specimen of a rich mineral combination.

Location: Cavnic, Romania.
