In oil and gas industry, classifying carbonate rocks is a major step in core and thin section description. Two classification systems have been widely used in the industry: Folk (1959,1962) Classification. Dunham (1962) Classification. Both classifications provide an indication of depositional energy setting and reservoir quality.

The Bureau of Reclamation (Reclamation) has adopted a classification system which is ...

Roundness (or angularity) is, hence, a measure of how much sediments have been transported by a current. Roundness is different from sphericity, which is, on the other hand, a measure of the shape of a clast. The external outline of a clast can be: – very angular: sharp edges separated by deep incisions. – angular: sharp edges separated by ...The Three Types of Rocks. Rocks are classified based on how they were formed. The three major types are igneous, sedimentary, and metamorphic rocks. This classification is essential to geologists as it provides critical information about the history of specific regions on Earth. These rocks change forms via the rock cycle.Chemical Sedimentary Rocks. Sedimentary rocks formed by the crystallization of chemical precipitates are called chemical sedimentary rocks.
