form of the mineral calcite. About 10% of sedimentary rocks are limestone and most cave systems are through limestone bedrock. The two most important constituents of limestone are calcite and dolomite. Limestone often contains magnesium carbonate, either as dolomite CaMg (CO 3) 2 or magnesite (MgCO 3) mixed with calcite.

What is the Acid Test? To most geologists, the term "acid test" means placing a drop of dilute (5% to 10%) hydrochloric acid on a rock or mineral and watching for bubbles of carbon dioxide gas to be released.The bubbles signal the presence of carbonate minerals such as calcite, dolomite, or one of the minerals listed in Table 1.
