Crystal Chemistry of Sedimentary Carbonate Minerals

Calcite, CaCO 3, is the most abundant carbonate mineral.This follows from the predominance of limestones over other carbonate rocks. In view of the existence of the other modification of CaCO 3, aragonite, such a conclusion is valid only when we know that most limestones consist essentially of calcite.That this is indeed the case had been …

Carbonates

The basic units of carbonate minerals are cations and the triangular carbonate groups (({rm CO}_3{^{2-}})).The crystal structure of carbonate minerals is strongly related to the ionic radius of the cation versus the oxygen ion (e.g., Reeder, 1990).As the Ca:O ionic radius ratio in CaCO 3 is close to the upper limit for 6-coordination, CaCO 3 can occur in …

Abstract The phase relations in the Na2CO3-(Fe0.87Mn0.06Mg0.07)CO3 system have been studied in Kawai-type multi-anvil experiments using graphite capsules at 6.0 GPa and 900-1400 °C.

An Overview of Zoning in Carbonate Minerals

Compositional zoning patterns in carbonate minerals consist of two major types that are distinguished by the relative spatial arrangements of growth surfaces and composition interfaces. Concentric zoning exists where the composition interface coincides with an existing or prior crystal growth surface, and it provides a temporal record of ...
