Dolomite. Dolomite is widely distributed in Texas except in the Coastal Plain and over the greater part of the High Plains. It occurs in beds of varying thickness and extent in rocks ranging from Precambrian to Cretaceous in age. Dolomite was mined from the Ellenburger Formation in Burnet County as an ore of magnesium during the 1940s.
