Mineral Planning Factsheet Calcite bgs.ac.uk

Crystalline calcite, which is the focus of this factsheet, is a common component of many mineral veins. It is associated with those veins carrying fluorspar baryte lead mineralisation that occur in limestones of Carboniferous age, particularly those in the Peak District of Derbyshire. Where these minerals are worked, the calcite is treated as waste.

For example, calcite (CaCO3) is a common vein mineral in rocks, and also a shell forming material in many life forms. Calcite of organic origin conforms to the above definition except for the requirement that it be inorganic. This is an inconsistency in the definition of a mineral that is generally overlooked.
