Limestone Wikipedia

Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs.Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.

Calcium carbonate crystals promote calcium SpringerLink

A large proportion of urinary stones have calcium oxalate (CaOx) as the major mineral phase. In these stones, CaOx is generally associated with minor amounts of other calcium salts. Several reports showing the presence of calcium carbonate (CaCO3) and calcium phosphate in renal stones suggested that crystals of those salts might be present in the early steps of stone formation. Such crystals

Formate Oxidation-Driven Calcium Carbonate Precipitation

Calcium carbonate precipitation was further confirmed from XRD, TEM, and SEM analyses (Fig. 2, Fig. 3, Fig. 4). The three possible calcium carbonate crystal polymorphs (i.e., calcite, vaterite, aragonite) were observed in the M. parvus OBBP cultures in 5 g liter −1 of calcium formate.
