Jun 10, 2008· Limestone Nutrient Content There are four types of carbonate-based limestone that are available. Calcite is pure calcium carbonate (CaCO 3, 40 percent Ca).Calcitic lime is composed of mostly CaCO 3 (> 30 percent Ca) with some MgCO 3 (<5 percent Mg). Dolomitic lime contains less CaCO 3 (<30 percent Ca) and more MgCO 3 (>5 percent) than calcitic lime.

Limestone vs Gritstone Compare Nature

Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate. Gritstone or grit is a hard, coarse-grained, siliceous sandstone. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks.
