Abstract
Limestone is classified as a carbonaceous sedimentary rock. In general, the term is applied only to those rocks in which the carbonate fraction exceeds the non-carbonate fraction. The carbonate may be calcite and/or dolomite. In addition to the primary constituents, there are contaminating minerals such as quartz, clay minerals, chalcedony (chert and flint), pyrite, feldspars and organic matter. The clay minerals are probably the most deleterious contaminates in carbonate rock.
