Dolostone is the name of a sedimentary rock that is dominantly composed of the mineral dolomite (CaMg(CO3)2). Dolomite is a carbonate mineral similar to calcite (CaCO3), the dominant mineral in limestone and marble. Dolostones are easily distinguished from limestones by using the dilute hydrochloric acid (HCL) test.

The rock material that comprises sedimentary rocks starts out as parts of other rocks, before it is weathered away, and carried by some transportation system, either wind or water, to the point where it is deposited, and then it finally solidifies (lithifies) into a sedimentary rock.

C. Classification of Sedimentary Rocks from Fragments: In almost all sedimentary rocks the constituents are of very small size like that of sand grains. These particles are classified into fine grained lutites of mm size forming mudstone, siltstone and shale and medium grained arenites with grains of mm to 2 mm size form orthoquartzite, greywacke and arkose.

Most of these rocks are limestones and cherts. Chemical sedimentary rocks are formed by direct chemical precipitation from water.

Chemical sedimentary rocks occur when components of water evaporate and previously dissolved minerals are left behind. These types of sedimentary rocks usually occur in arid areas; like gypsum and salt deposits. Examples of chemical sedimentary rocks are: chert, dolomites, flint, rock salt, iron ore and some types of limestone. 2. Clastic

Kona Dolomite History: Kona Dolomite is an ancient rock in which formations of fossil stromatolite (bluegreen algae) occur. The stone is between to billion years old. These stromatolite formations are from some of the first life on earth. These fossil formations are found in the lower eras of the Middle Precambrian Period.
