What type of classification is limestone?
sedimentary stone
Limestone is a sedimentary stone with 50% by weight calcite or calcium carbonate (CaCO3) content. However, commercial limestone usually has more than 50% calcium carbonate. Limestone is a “clastic” sedimentary stone.
What mineral group is primary minerals in limestone and marble?
Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite.
Is limestone chemical or clastic?
Limestone is not a clastic sedimentary rock; it is a chemical sedimentary rock.
What is limestone chemistry?
Limestone is a sedimentary rock made of calcium carbonate (CaCO3), usually in the form of calcite or aragonite. It may contain considerable amounts of magnesium carbonate (dolomite) as well. However, minor constituents of clay, iron carbonate, feldspar, pyrite, and quartz is also commonly present.
How is limestone created geologically?
It can be formed with the help of living organisms and by evaporation. Ocean-dwelling organisms such as oysters, clams, mussels and coral use calcium carbonate (CaCO3) found in seawater to create their shells and bones. The water pressure compacts the sediment, creating limestone.
What molecules are in limestone?
Limestone is a sedimentary rock composed mainly of calcium carbonate (CaCO3). However, it can also contain magnesium carbonate, clay, iron carbonate, feldspar, pyrite and quartz in minor quantities, according to the Encyclopaedia Britannica.
Is limestone clastic?
Limestone is a sedimentary rock composed mainly of calcium carbonate (CaCO3), usually calcite, sometimes aragonite. It may also contain considerable amounts of magnesium carbonate ( dolomite , (CaMg)(CO3)2). Most limestones have a granular texture, but limestone can also be massive, crystalline or clastic.
What type of sedimentary rock is limestone?
Limestone is a sedimentary rock in the class known as chemical sedimentary rocks. It is composed chiefly of calcite, CaCO 3, and constitutes about 10 percent of all sedimentary rocks. Limestone may form inorganically or by biochemical processes.
What are the types of limestone?
The many types of limestone include chalk, coral reefs, animal shell limestone, travertine and black limestone rock.
What is limestone made from?
Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth’s sedimentary crust.
