Where were most coal deposits formed?
Coal starts its cycle of formation with the accumulation of plant material in swamps or bogs. Decaying plant matter that builds up at the bottom of bogs or swamps is called peat. After other sedimentary layers bury the peat deposit, the weight of these sediments builds up and compacts it.
Which valley is richer in coal deposits?

Which state has the highest quality coal?
About 55% of total U.S. coal production was mined in the Western coal region. Wyoming, the largest coal-producing state in the United States, produced 39% of total U.S. coal production and 72% of the coal mined in the Western coal region.
Is coal still being formed?
Coal is very old. The formation of coal spans the geologic ages and is still being formed today, just very slowly. Below, a coal slab shows the footprints of a dinosaur (the footprints where made during the peat stage but were preserved during the coalification process).
Which is the purest form of coal?
High grade (HG) and ultra high grade (UHG) anthracite are the highest grades of anthracite coal. They are the purest forms of coal, having the highest degree of coalification, the highest carbon count and energy content and the fewest impurities (moisture, ash and volatiles).
Why is chotanagpur called Ruhr of India?
