A rapid automated method is described for differentiation and quantitative determination of calcite and dolomite in earth materials. The method is based on differential pseudo-first-order kinetic rates of dissolution of the two carbonate species when reacted with excess of 5M HCl. The method employs manometric measurement of acid-liberated CO2 with a differential pressure transducer coupled to a strip chart recorder. Tested on calcite and dolomite singly and together in geologic materials, the method is highly discriminatory, highly sensitive, and extremely rapid. Theoretical treatments of pseudo-first-order kinetic reactions and of manometric measurements associated with the method are reviewed.
