Physical properties
Hardness of 1.5 to 2.5 on the Mohs scale, black to dark brown color, sub-metallic to dull luster, amorphous crystal structure, and a dark brown to black streak.
Formation & geological history
Formed from compressed plant debris in ancient swamps and wetlands over millions of years during the Carboniferous period and later eras.
Uses & applications
Primarily used for electricity generation, steel production, and industrial manufacturing.
Geological facts
Bituminous coal is the most abundant type of coal and contains high amounts of carbon, making it an efficient fuel source.
Field identification & locations
Identified by its dark color, relative lightness, and propensity to soil hands; commonly found in sedimentary basins worldwide.
