May 15, 2020 Chalk is made from calcite, which reacts with acids. In the reaction the chalk is also eaten away. Over a long period of continued acid rain, monuments made from marble (a form of calcite) and buildings made of limestone will be eaten away as the acid rain slowly dissolves them. 6)
Physical Weathering Of Marbles Caused By Anisotropic
Marbles as building stones as well as in their natural environments show complex weathering phenomena. the most important damage scenario is based on the highly anisotropic thermal expansion coefficient α of calcite, i.e. extreme expansion parallel and contraction normal to the crystallographic c-axis.

Calcite Rocks And Minerals For Earth Science Fun
Calcite, or calcium carbonate, is one of the minerals that helps form limestone and marble. many marine animals use this mineral to construct their shells. foraminiferons, bryozoans, brachiopods, and oysters all use calcium carbonate to make their shells.

Calcite, Limestone And Marble Earth Sciences Museum
Marble is a metamorphic rock formed by the alteration of limestone by heat and pressure. the calcite in the limestone changes and fossils and layering in the original limestone disappear as interlocking grains grow. if the limestone is pure, a white marble is formed.
