Calcite - Mineral Properties, Photos and Occurence

2018-8-11 · Calcite also exhibits several twinning types. Such variability results in several thousand known crystal forms of calcite. Other polymorphs of calcium carbonate are hexagonal aragonite and vaterite, which are metastable and recrystallize into calcite under Earth's near-surface conditions. However, this process can take many million years to finish.

2016-3-1 · Biomineralization is a naturally occurring process in living organisms. In this review, we discuss microbially induced calcium carbonate precipitation (MICP) in detail. In the MICP process, urease plays a major role in urea hydrolysis by a wide variety of microorganisms capable of producing high levels of urease. We also elaborate on the different polymorphs and the role of calcium in the ...

Calcification - an overview | ScienceDirect Topics

Calcification is the synthesis of solid calcium carbonate from dissolved substances, whether passively by spontaneous formation of crystals in a supersaturated solution (inorganic calcification) or actively through the intervention of organisms (biocalcification). The building of coccoliths by coccolithophores is a major fraction of the total biocalcification taking place in seawater.
