Physical properties
Hardness of 1.5-2.5 on Mohs scale, black to dark brown color, subadamantine to dull luster, amorphous crystal structure, and a dark black streak.
Formation & geological history
Formed from the compaction of plant debris deposited in ancient swamp environments over millions of years during the Carboniferous period.
Uses & applications
Primarily used for electricity generation, steel production, and industrial heat generation.
Geological facts
Bituminous coal is the most abundant type of coal and contains high amounts of carbon and volatile matter.
Field identification & locations
Identified by its relative softness, dark layered structure, and dirty residue left when handled; commonly found in sedimentary coal basins worldwide.
