Calcite name is from chalix the Greek word for lime. This is a most amazing yet, common mineral. Comprising about 4% by weight of the Earth’s crust and formed in many different geological environments. Calcite can form rocks of considerable mass and constitutes a significant part of all three major rock classification types. It forms oolitic, fossiliferous and massive limestones in sedimentary environments. Calcite serves as the cements for many sandstones and shales. Limestone becomes marble from the heat and pressure of metamorphic events. Calcite forms the major portion of many hydrothermal veins. Sea creature like Shells and Plankton and others form a sedimentary layer on the ocean floor. This is the start of where Calcite comes from.
