Why is it important?
To review the relationship between coal sample's qualities and their geologic histories.
Perspectives
The differences in coal ranks of those samples have difference geologic histories. Those factors that influencing of coal ranks are rocks age, depositional environment, temperature, pressure, and recent geologic events.
