In both groups, the alteration of calcite and aragonite to dolomite may be very selective. Fossils composed of pure calcite may be less likely to be altered and may remain as calcite fossils in
but with a different crystal structure from calcite), dolomite (CaMg(CO 3) 2), and magnesite (MgCO 3) (Boynton, 1980). Line can be categorized as either high calcium or dolomitic.
The primary mean to recognize calcite in the field and to distinguish it from dolomite is the HCl test: calcite reacts with HCl (hydrochloric acid) diluted in a water solution at 10%, producing a
