Answer 1

Limestone is predominately Calcium Carbonate

Answer 2

Formation Limestone is chiefly composed of calcium carbonate. It is a sedimentary rock, which means that it is formed by the collection of other minerals coming together to bond at a structural level. This most commonly occurs when lime builds up in oceans, then washes ashore and dries out.

Answer 3

No mineral makes up limestone. It is made up of the hard parts of dead plants and animals.

Answer 4

Limestone is a sedimentary rock,  formed on the seafloor, made up of calcium carbonate- CaCO3 as its main mineral. Some limestones were formed by a chemical deposition process and others by the accumulation of shells from minute sea creatures.

Limestone often contains variable amounts of silica in the form of chert or flint, as well as varying amounts of clay, silt and sand within the rock. However, the primary source of the calcite in limestone is most commonly marine organisms.

Invertebrates take calcite from sea water to construct their shells. When they die the shells fall to the sea bed. Areas where there is little deposition of mud or sand are ideal for the formation of limestone.

Answer 5

largely calcite, with secondary dolomite, aragonite.and small quantity's of chalcedony.and also some quartz and silicates and also some clays as well.
