Limestone (Classification, Uses)

Limestone is a sedimentary rock; it occurs primarily on the seafloor where calcium carbonate-rich ('calcareous' material) material accumulates. This calcareous material can be originally organic, chemical, or detrital. About 10% of the sedimentary rocks are lime. Karst landscapes are caused by the solubility of limestone in water and poor acid …

Classification of Carbonate Rocks—A Symposium

The writers have reviewed past usage of these terms and, from this review, propose a threefold classification of skeletal limestone deposits based on their organic content, shape, and origin. Skeletal limestones are defined as rocks which consist of, or owe their characteristics to, the in-place accumulation of calcareous skeletal material.

Basis for the classification is (1) relative proportion of allochems and carbonate mud, (2) sorting of allochems, and (3) rounding of allo-chems. A complete parallel exists between these limestone types and the sequence of textural maturity in sandstones, even to the existence of textural inversions.
