Mudrocks commonly contain few rock fragments. Finding the center can be done graphically, but a more accurate center (center of gravity) can be found by calculation (Ehrlich and Weinberg, 1970). If boring activities are prolonged and intense, the entire surface of a grain may become infested by these aragonite- or Mg-calcite-filled borings, resulting in the formation of a thin coat of micrite around the grain.

Folk (1959) proposed the term micrite as a contraction for microcrystalline calcite; this term has been universally adopted to signify very fine-grained carbonate sediment. It is used loosely to include all carbonate mud, including aragonite muds; that is, all microcrystalline carbonate.

Geology also plays a role in geotechnical engineering and is a major academic discipline. The majority of geological data comes from research on solid Earth materials.

Several references listed under Further reading provide interested readers with a starting point for further literature research. 13.2 Characteristics of organic matter in carbonaceous sedimentary rocks 13.2.1 Principal kinds of organic matter Organic content of carbonaceous sedimentary rocks is the characteristic that particularly distinguishes them from other sedimentary rocks , cited: Rocky Mountain Carbonate Reservoirs: A Core Workshop (Sepm Core Workshop No. 7/Golden, August 10-11, 1985) download Rocky Mountain Carbonate Reservoirs: A Core Workshop (Sepm Core Workshop No. 7/Golden, August 10-11, 1985). The most common cements are calcite and orbs. There are also smaller amounts of iron oxides, and clay minerals, and gypsum, and dolomite, and other kinds of minerals, but the most common are calcite and orbs. The process of crystallization of these new minerals and cementation basically occur jointly or at the same time, but certain chemical deposits are crystallized directly; others are recrystallized as the grains dissolve ref.: Sedimentary Geology, International Journal of Applied and Regional Sedimentology, 1988, Sedimentary Geology, 54 (4) :.

Thus, during catagenesis, low- to medium-molecularweight hydrocarbons are formed at lower temperatures, with lighter hydrocarbons and some methane forming at the high end of the temperature range above about 120 oC.

And most sedimentary rocks consists of small particles that have a long and fascinating story to tell from their long journey behind them. First we need to make clear what sediment is!
