The Rajmahal Hills are located in the Santhal Pargana division of Jharkhand, India. They were located on the northern margin of the Gondwana supercontinent, and its hills are today inhabited by the Sauria Paharia people whilst its valleys are dominated by the Santhal people.[1] The hills span over an area of 2,600 km2 (1,000 sq mi).[2]

Volcanic activity during the Jurassic resulted in the formation of the Rajmahal Traps. The hills are approximately located at 25°N 87°E / 25°N 87°E / 25; 87.[3]

The Rajmahal hills are named after the town of Rajmahal which lies in the eastern Jharkhand. The hills trend north-south with an average elevation of 200–300 m (660–980 ft), from the Sahibganj district to the Dumka district. The River Ganges wanders around the hills changing the direction of flow from east to south.

In the early nineteenth century, Francis Buchanan-Hamilton travelled through the Rajmahal hills. From his description, the hills appeared impenetrable, a zone where few travellers ventured, an area that signified danger. Wherever he went, people were hostile, apprehensive of officials and unwilling to talk to them. In many instances, they deserted their villages and absconded.[4]


Plant Fossil bearing Inter-trappean beds of Rajmahal Formation here has been declared the National Geological Monuments of India by the Geological Survey of India (GSI), for their protection, maintenance, promotion and enhancement of geotourism.[5][6][7] The Rajmahal hills are home to plant fossils which are 68 to 145 million years old. The Birbal Sahni Institute of Palaeobotany in Lucknow has a collection of these fossils. The fossils here have attracted geologists and palaeobotanists from all over the world. There are fears of these fossils disappearing now, as the state government has in 2018 given out a mining lease in the area to private companies.[2]
