Calcite is a usually white, clear, pale-yellow or blue orthorhombic mineral. Calcite occurs in many different forms and is the main component of chalk, limestone, and marble. It is a polymorph of aragonite. It is a rock-forming mineral with a chemical formula of CaCO 3.

Companion work shows that calcite precipitation can occur at the water-sediment interface of the river and this may involve SRP removal. The data, as a whole, define an apparent bound for calcite solubility control where in the presence of nucleating centres, SRP must be less than 4 mM-P l -1 and DOC must be less than 150 mM-C l -1 : a

25.09.2012· Microstructure‐based finite-element analysis with a microcracking algorithm was used to simulate an actual degradation phenomenon of marble structures, i.e., microcracking. Both microcrack initiation and crack propagation were characterized, as were their dependence on lattice preferred orientation (LPO), grain shape preferred orientation (SPO), grain size, marble composition (calcite

By: Kelly Snyder and Peter Russell Calcite A mineral consisting largely of calcium carbonate (CaCO3 ). Next to quartz, it is the most abundant of the Earth's minerals. Crystallizing in the hexagonal system, calcite is noted for its wide variety of crystalline forms.

Along with calcite globules, calcium oxalate crystals were present on the surface of marble: dipyramidal (almost isometric) weddellite crystals and plate-like whewellite crystals. The size of weddellite crystals varies from 10 to 25 μm. Whewellite plate-like crystals (5–40 μm) form stack-like intergrowths. In the experiment with glucose concentration of 10–30 g/L at ~pH 5

Highly transparent calcite is called optical spar. Although calcite can form spectacular crystals, it is usually massive, occurring either as marble (p.301) or as limestone (p.319). It is also found as fibers, nodules, stalactites, and earthy aggregates. Calcite specimens can occur in metamorphic deposits, igneous rocks, and hydrothermal veins.

Calcite is the most stable form of calcium carbonate and a primary ore of calcium. Calcium carbonates are a very abundant group of minerals and in their purest form, they are completely colorless with excellent transparency.
