While most of Bengal is flat alluvial plain Asansol subdivision lies on exposed Gondwana rocks and consists mostly of undulating laterite soil. It forms the lower Chota Nagpur plateau, which occupies most of Jharkhand. It is located between the Damodar and Ajay rivers. Another river, Barakar, joins the Damodar near Dishergarh. A small rivulet, Nunia, flows past Asansol. While Dhanbad district lies on the western side, Durgapur sub division of Bardhman district lies on the eastern side. To the south, across the Damodar river are the Purulia and Bankura districts. To the north are Dumka and Birbhum districts.
