Carbonate rocks

Carbonate rocks are composed of two minerals

Calcite CaCO3

Dolomite Ca Mg (CO3 )

The principal constituents of limestones are

1. Allochemical components (ooids, bioclasts, peloids and intraclasts)

2. Micrite (microcrystalline calcite: refers to a crystal size less than 5 um)

3. Sparite (sparry calcite; refers to crystals of 5 um or more in diameter)

A limestone section which has been treated with Alizarine Red S. Calcite showing shades of pink, red, and brown. The dolomite is colorless to grey and appears to be replacing matrix and/or cement.

Dolomitic carbonate are classified according to their dolomite content:

dolomite

0-10% Limestone

10-50% dolomitic limestone

50-90% calcitic dolomite

90-100% dolomite
