Respuesta :
Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3) in the form of the mineral calcite. It most commonly forms in clear, warm, shallow marine waters. It is usually an organic sedimentary rock that forms from the accumulation of shell, coral, algal, and fecal debris. It can also be a chemical sedimentary rock formed by the precipitation of calcium carbonate from lake or ocean water.
Calcium carbonate is one f the most commonly found material found in limestone rocks. The composition of calcium and magnesium as it commonly made of fossils, shells, and debris.
- Calcite is a mineral that is highly found in limestone. More than 50 % of the rocks are made from this mineral.
- About 95% of calcite and 5% is dolomite. Other minerals include quartz, feldspar, clay minerals, pyrite, siderite in small percentages.
Hence the rocks can be easily be identified by the white to grayish color and presence of lime content in rocks.
