Calcite – Geology is the Way
Calcite is the most abundant carbonate on Earth. It is one of the forms of calcium carbonate (CaCO 3) and its name derives from the Latin word for lime, calx, and the related German word calcit. It was named as a mineral by Gaius Plinius Secundus (Pliny the elder) in 79 CE. Pressure (P) – Temperature (T) diagram showing the stability fields ...

In the marine environment, hydration of Mg and the problem of cation ordering combine to prevent dolomite precipitation. Metastable magnesian calcite forms instead. Once magnesian calcite is formed, pressure increases (less than 1 kbar) in the marine environment may cause sufficient additional disequilibrium to produce dolomite.
