Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (Ca C O 3). The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as "calcite". Other polymorphs of calcium ...
Calcite is a negative uniaxial crystal that has high birefringence, wide spectral transmission and availability in reasonably sized rhombs.
The highMg calcite composition suggests a red algal affinity, yet the unordered microcrystalline structure of the walls does not exclude a microbial origin, suggesting also the possibility that the primary metastable mineralogy ...
