Limestone - nanowerk

Limestone is a common type of carbonate sedimentary rock. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes have likely been more ...

Aspects of the biological weathering of Limestone

It is concluded that solution of the limestone to form dints and grikes mainly occurred when there was a covering of glacial drift which is now receding. Solution is still occurring under the drift by a process of weathering which is accomplished by soil-acids of biological origin. The term biological weathering is proposed for the process.

How does weathering affect limestone? - Internet Geography

2021-8-31  Weathering is the breakdown of rock by physical, chemical or biological processes. Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone. This causes the limestone to dissolve. Carbon dioxide from the respiration of animals (and ourselves) is one cause of increased carbon dioxide in the atmosphere.

6.2 Chemical Sedimentary Rocks – Physical Geology

Biological processes are important in the formation of some chemical sedimentary rocks, especially limestone and chert. For example, limestone is made up almost entirely of fragments of marine [1] organisms that manufacture calcite for their shells and other hard parts, and most chert includes at least some of the silica tests (shells) of tiny ...
