Calcarenite is a type of limestone that is composed predominantly, more than 50 percent, of detrital (transported) sand-size (0.0625 to 2 mm in diameter), carbonate grains. The grains consist of sand-size grains of either corals , shells , ooids , intraclasts , pellets , fragments of older limestones and dolomites , other carbonate grains, or ...

2014年1月1日 · Calcarenite is a clastic limestone consisting predominantly of sand-grade (1/16 to 2mm in diameter) calcitic or aragonitic particles (allochems, Folk, 1959); it is a consolidated carbonate sand. Grabau (1904) introduced this term as calcarenyte in his genetic classification of sedimentary rocks to convey the basic calcareous composition ...

Muddy fossiliferous calcarenite limestone. It is mainly a bioclastic calcarenite framestone with a muddy component. It contains abundant in situ corals of 15 or more species. Bivalves and gastropods are abundant. The rocks were deposited in a marine reef-flat environment protected from the open sea. Molluscan packstone limestone. Bivalve ...

2021年11月27日 · Calcarenite is a type of limestone, the carbonate equivalent of sandstone, composed mainly of coral, shells and extinct creatures, compressed over aeons into a solid mass of calcium carbonate, commonly referred to as ‘coral stone’.

2023年11月24日 · Calcium carbonate is a common mineral that acts as a cementing agent in the formation of limestone. This mineral often comes from the dissolution of shells and other organic material. As compaction and cementation progress, the once loose sediments solidify into rock.

2024年12月29日 · Discover 12 fossiliferous limestone types, classified and explored, revealing sedimentary rocks, calcite compositions, and ancient fossil formations, in a comprehensive geological guide to limestone classification and characteristics.

2002年12月1日 · The examined calcarenites, sampled from three quarry districts located in Apulia (southeastern Italy), are fine-grained and coarse-grained grainstones (“A” and “D”) and medium-grained packstones (“B”) belonging to a plio-pleistocenic formation (Calcarenite di Gravina) outcropping in the whole region.

calcarenite Calcareous sediment in which a high percentage of the clasts can be of quartz within a calcareous matrix or, more generally, a clastic limestone in which both clasts and matrix are calcareous. Calcarenites are characterized by a particle range of 0.006–2.00 mm in diameter.
