Whewellite, a major mineral of calcium oxalate in the plant kingdom (also found in mammalian kidney stones) occurs in multiple morphologies including prisms and radially aligned crystals known as druses. ... Aragonite is the more soluble mineral at oceanic T and P, and the dominant carbonate mineral in deep-sea sediments is calcite. Calcite ...
Two analogues of aggregates (calcite and dolomite) found in nuclear power plant (NPP) concrete have been neutron irradiated to fluences up to 2 × 1020 n/cm2 at 52 °C and 4 × 1019 n/cm2 at 95 °C (E > 0.1 MeV). X-ray diffraction studies showed that these aging conditions affected crystallography of both calcite and dolomite, with both …
A plant (jack bean) extract can function as a urease catalyst, similar to those of certain microorganisms such as Sporosarcina pasteurii, which can decompose urea into carbonate and ammonium ions.Carbonate ions decomposed from urea can combine with calcium ions to form calcium carbonate (usually calcite mineral).

The formulation from this invention was employed as a plant booster and mineral fertilizer in the production of potatoes.
calcite formed via mineral precipitation of the Canavalia ensiformis crude extracts. 2. Calcite Precipitation by Canavalia ensiformis Crude Extracts To precipitate calcite, Canavalia en siformis extract was prepared and mineral precipitation experiments were conducted. Purified urease (urea amidohydrolase; EC 3.5.1.5) was purchased from
Overview of calcite mineral physical properties, structure and its origin and occurence in nature.
Calcite - Mineral, Crystals, Sedimentary Rocks: A large percentage of the calcite in rocks was deposited in sedimentary environments; consequently, calcite is a constituent of several diverse sediments, sedimentary rocks, and their metamorphosed products. A minor amount of the Earth's calcite is of magmatic (i.e., igneous) origin; it is …
