2020-5-26Limestone is a sedimentary rock, made up mostly of the mineral calcite, a form of calcium carbonate, CaCO 3.. The calcium carbonate is originally produced by living organisms. Later, some of it goes into solution in sea water. Limestone rocks include mainly organic remains and precipitated carbonate.. Limestone makes up about 10 of the total volume of all sedimentary rocks.

Thus, according to Folk 1962, the limestone is a sparse foraminiferal pelbiomicrite. At the time of deposition, its texture was that of grains of coarse silt and larger sizes 0.03 mm, comprising 10 of the rock and supported by a muddy matrix. Thus, according to Dunham 1962, the limestone is a wackestone. AppleCORE Sheets
