Geology limestone
Rocks belonging to the White Limestone Group cover about two thirds of the surface area of Jamaica and were deposited from the late Eocene to the early or middle Miocene (some 12 to 45 million years ago). The White Limestone accumulated in two different dpositional settings: shallow-water environments and deep-water environments.Limestone is used as gravel for roads, as an ingredient in cement and lime is used to enrich Iowa farm fields. Buildings around the state feature actual stones including glacial erratics, limestone blocks and Sioux Quartzite. On a much smaller scale, local artists have mined Iowa’s geologic treasures for use in their work.

Oct 20, 2023 · As now understood Ocala limestone comprises all rock of Eocene age exposed in Florida. This includes "Orbitoidal," Nummulitic," and "Millolitic" limestones of Dall as well as "Peninsular" limestone as interpreted by Matson. The Ocala limestone is of Jackson (late Eocene) age. Source: US geologic names lexicon (USGS Bull. 896, p. 1526-1527). Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg (CO 3) 2. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. Limestone that contains some dolomite is known as dolomitic limestone.Industrial minerals occur in a vast range of geological associations. Among the most important is the Murray Basin, a world-class province for heavy mineral sands. Limestone and dolomite are produced in large quantities.
