Metamorphism of Dolomites and Limestones SpringerLink

2011-4-22 There are two main types of carbonate rocks, dolomites and limestones. The first is modally dominated by dolomite (CaMg (CO 3) 2), the second by calcite (CaCO 3) and there is a complete gradation between the pure dolomite and limestone “end members” indicated by the rock names, calcitic dolomite, dolomitic limestone, magnesian limestone.

Regional Metamorphism - an overview ScienceDirect Topics

Caineng Zou, in Unconventional Petroleum Geology, 2013 (1) Regional Metamorphism and Rock Type Regional metamorphism occurs over broad areas in the lithosphere, possibly influenced by the heat supply. Regional metamorphic rock results from regional metamorphism and usually develops a flaky texture. It is distributed most widely in metamorphic rock, from Archean to even Cenozoic.
