What is coal? - USGS

Coal is a sedimentary rock made predominantly of carbon that can be burned for fuel. Coal is readily combustible, black or brownish-black, and has a composition that, including inherent moisture, consists of more than 50 percent by weight and more than 70 percent by volume of carbonaceous material. It is formed from plant remains that have been compacted, hardened, chemically

Is Coal a Renewable Resource? - Help Save Nature

Coal is basically a sedimentary rock, a combustible sedimentary rock to be precise, that is found in rock strata in layers which are referred to as 'coal beds' or 'coal seams'. It is primarily made up of carbon, but also has significant amount of hydrogen and sulfur in it.


Anthracite: Sometimes also called "hard coal," anthracite forms from bituminous coal when great pressures developed in folded rock strata during the creation of mountain ranges. This occurs only in limited geographic areas –primarily the Appalachian region of Pennsylvania. Anthracite has the highest energy content of all coals & is

Coal measures - Wikipedia

The coal measures is a lithostratigraphical term for the coal-bearing part of the Upper Carboniferous System. In the United Kingdom, the Coal Measures Group consists of the Upper Coal Measures Formation, the Middle Coal Measures Formation and the Lower Coal Measures Formation. The group records the deposition of fluvio-deltaic sediments which consists mainly of clastic rocks (claystones ...

Where Are All the Human Fossils? | Answers in Genesis

(Merely finding rock around an implement does not prove it is pre-Flood.) For example, it has been claimed that a gold chain was found in black coal.2 However, the artefact evidently was exhibited as a clean gold chain with no coal clinging to it, so we see no evidence that the chain was actually found in the coal, just the claim that it was ...


Coal and petroleum are only found in sedimentary strata—the only place fossils are found. All the evidence points to a rising worldwide Flood as the event which laid down these strata. Research scientists have discovered that coal and oil can be made fairly rapidly through quick burial and compression.— pp. 47-49.
