Dolomite In Metamorphic Rock

Mineralogy: Contains a high proportion of dolomite (the mineral and the rock have the same name). Detrital minerals and secondary silica (chert) may be present. Field relations: Dolomites are usually interbedded with other limestone s and are commonly associated salt and gypsium deposits.

Formation Of Dolomite | Composition

Dolomite Formation. Dolomite formation took place millions of years ago. There are a variety of Dolomite Uses and the Dolomite Reserves are found in many countries around the world. The rocks in the earth’s crust continuously undergo changes in their composition which leads to formation of other rocks. Each rock has a unique formation process.
