Clastic limestone
Limestone’s most common use is as a crushed construction material, serving as a base for roads and ballast in railroads, but it also combines with crushed shale in a kiln to make cement and serves as an aggregate material in concrete. Limes...Limestone is formed from the accumulation of shells and skeletal remains of marine organisms. These deposits are formed by either chemical deposition or biological activity. This would suggest that limestone is organic in nature. However, today’s definition of “organic” requires that it must contain a large percentage of carbon.

The geological structure of the study site is primarily fault. ed and fold. The direction of normal fault is less uniform, but in the West tends to beIf the rock is clastic, then the grains or broken fragments will be visible. If the rock is non-clastic, then no fragments will be visible and the rock will be crystalline (composed of crystals). To touch, limestone can either be smooth or rough to touch, this will depend on composition, mode of formation and weathering.Breccia forms where broken, angular fragments of rock or mineral debris accumulate. One of the most common locations for breccia formation is at the base of an outcrop where mechanical weathering debris accumulates. Another is in stream deposits a short distance from the outcrop or on an alluvial fan. Some breccias form from debris flow deposits.The most common chemical sedimentary rock, by far, is limestone.

Much of the production from the USA has also been from clastic reservoir rocks. But there are some notable exceptions. For example, the Permian Basin of the southwestern U.S.A. is a carbonate (limestone) reservoir as is the huge oilfields in the Middle East.Some non-clastic rocks are limestone, chert, dolostone, gypsum, halite (rock salt), diatomite, and chalk.
