Asansol Sadar subdivision is part of the Ajay Damodar Barakar tract. This area is sort of an extension of the Chota Nagpur Plateau. It is a rocky undulating area with laterite soil, with the Ajay on the north, the Damodar on the south and the Barakar on the west. For ages the area was heavily forested and infested with plunderers and marauders. The discovery of coal in the 18th century led to industrialisation of the area and most of the forests have been cleared. Maithon Dam of Damodar Valley Corporation, located in Jharkhand, is on the border of this subdivision.
