Unconventional Geology Origin Of Carbonate Rocks

Dec 03, 2011 Origin of Carbonate Rocks In geology, carbonates are a class of sedimentary rocks compose primarily of carbonate minerals. Two major types are limestone, which is composed of calcite or aragonite different crystalline forms of CaCO3 and dolostone, which is composed of the mineral dolomite CaMgCO32.

Carbonates Amp Other Rocks

Carbonate Rocks. The carbonate rocks make up 10 to 15 of sedimentary rocks. They largely consist of two types of rocks. Limestones which are composed mostly of calcite CaCO 3 or high Mg calcite Ca,MgCO 3, and . Dolostones which are composed mostly of dolomite CaMgCO 3 2. Because carbonate minerals in general are soluble in slightly acidic waters, they often have high porosity and ...

Carbonate Sedimentary Rock Classification

Oct 26, 2000 Limestones are not single composition rocks but a group of related rocks all composed of CaCO 3 and reacting with dilute HCl acid. Limestone CaCO 3 is also chemically related to dolomite CaMgCO 3 2.Because all these rocks have CO 3 - - in common they are called the carbonates.The composition of most carbonates is derived from a combination of biological and chemical components.

A Review Of The Nature And Origin Of Limestone

Sep 01, 2019 1. Introduction. Porosity is perhaps the most important petrophysical property of a carbonate rock. Pore abundance storage capacity and connectivity permeability are routinely used to characterize limestone reservoirs in terms of economic value, and as a means of assessing diagenetic alteration Lucia, 2007 Moore and Wade, 2013.Whereas conventional porosity models focus on the ...
