Origin of limestone
Limestone Wikipedia
Limestone (calcium carbonate CaCO3) is a type of carbonate sedimentary rock which is the main source of the material lime It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO3 Limestone forms when these minerals precipitate out of water containing dissolved calcium 展开2012年9月28日 Limestone is a very common sedimentary rock consisting of more than 50% calcium carbonate Although it occurs in many different forms, its origins can be traced back to either chemical or biochemical processes that Limestone origins Science Learning HubLimestones originate by three main processes: (1) precipitation of calcium carbonate in an initially stony condition, as in travertine and organic reefs; (2) lithification of calcium carbonate Chapter 5 Origin and Occurrence of LimestonesLimestones originate by three main processes: (1) precipitation of calcium carbonate in an initially stony condition, as in travertine and organic reefs; (2) lithification of calcium carbonate Chapter 5 Origin and Occurrence of Limestones ScienceDirect
