Calcite as a rock forming mineral. Calcite is very important rock forming mineral. Many marine sediments - like marlites, schists, opoka and others - contain significant amounts of calcite. Limestone is made of almost pure calcite. When these sediments are buried during subduction into the Earths crust or get into the contact with hot magma, they are metamorphed into marbles or calc-silicate ...

The composition of limestone | What is .

Limestone is a sedimentary rock, most of which originally formed by the accumulation of sediments on the sea floor (although some formed in fresh water). These sediments, which were afterwards turned to limestone rock, are composed of over 50 per cent carbonate minerals. There are three main components in limestone: calcite and aragonite; dolomite
