Phosphate minerals occur in most members of the Lexington Limestone, principally the Tanglewood, Millersburg, and Grier Limestone, and parts of the Lexington which were mined in the early 1900''s. Although commonly called collophane, the phosphates are actually cryptocrystalline apatite, a calcium phosphate.

a replacement of preexisting limestone and this replacement process is known as dolomitisation. The process is often incomplete and rocks termed ''dolomite'' are usually a combination of dolomite, dolomitic limestone and limestone. Dolomite deposits are, therefore, usually associated with limestones. This fact, together

Dolomite serves as the host rock for many lead, zinc, and copper deposits. These deposits form when hot, acidic hydrothermal solutions move upward from depth through a fracture system that encounters a dolomitic rock unit. These solutions react with the dolomite, which causes a drop in pH that triggers the precipitation of metals from solution.

What is limestone, shell and dolomite? Limestone, shell and dolomite are types of marine deposits that have accumulated in Florida over millions of years during times when the state was covered over with seawater or shallow marshes. During this time, limestones formed by chemical deposition and the accumulation of shells from sea creatures.

Phosphate rock mining began in the Western United States in 1907 and in North Carolina in 1966. Phosphate rock production capacity doubled from 1960 to 1970 in response to increased demand for fertilizer and the shift to multinutrient, highanalysis fertilizers. Throughout the 20th century, fertilizer production was the major use of phosphate rock.
