Dec 03 32 Limestone vs Dolomite Both limestone and dolomite are types of rock made of carbonate residu The patterns of the way they behave chemically are almost the same with varied intensiti However the structure and the formation of these rocks are quite different Limestone Limestone mainly consists of two types of minerals namely calcite and aragoniteMarble is a metamorphic rock resulting from the recrystallization of limestone under high pressure and temperature Whether chalk limestone dolomite or marble all carbonate rocks are subject to erosion These dissolve under the influence of wind temperature and water and the cycle is ready to start anew
