Additionally, due to their unique nature, limestone hills result in unique flora and fauna that evolve to adapt to their environment.

11.05.2006One problem with the concept of Ricken ( 1986, 1987) is, however, that the uncompacted appearance of the limestone beds is incompatible with cementation in the deep burial environment. This leaves the question of the source of the cement in the uncompacted micritic limestones ("cement supply problem" of Bathurst 1970, 1976).

Limestone is calcium carbonate (CaCO3). It is mainly composed of the skeletal remains of marine organisms. Geologically, limestone occurs as a sedimentary layer over bedrock. As such it is relatively easy to extract through quarrying. Limestone is removed from the quarry, crushed and transported to steel mills. Coke Coke is produced from coal.
