Abstract
Geochemistry of coal seams is variably affected by weathering and natural heating. Weathering of coal implies natural oxidation taking place at low temperature (< 30°C) for several years. In contrast, natural heating is a high temperature event and occurs due to implacement of plutonic or invasion of volcanic rocks into coal seams often for short durations or self-burning of coal seams due to forest fire or lightning.
