Coal Deposits an overview ScienceDirect Topics

The distribution of worldwide coal deposits is uneven, which is the result of peat formation at different times in the geological record in predominantly tropical latitudes and the subsequent drift of the continents to their present-day positions. The major regions with coal deposits are located in the Northern Hemisphere, whereas the regions in the Southern Hemisphere, with the exception of

Coal deposits Formation Coalification. In geologic terms, coal is a sedimentary rock containing a mixture of constituents, mostly of vegetal origin.Vegetal matter is composed mainly of carbon, hydrogen, oxygen, nitrogen, sulfur, and some inorganic mineral elements.When this material decays under water, in the absence of oxygen, the carbon content increases.

The Geology of Coal KET Education

The Geology of Coal. In this video, a geologist describes how coal, a sedimentary rock, was formed when organic materials piled up in swamps millions of years ago. Over time, heat and pressure transformed the buried materials into peat and into various forms of coal. The geologist shows samples of low- and high-sulfur coal.

Coal

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
