• The hills are known for their rich deposits of volcanic rocks known as Rajmahal Traps, which date back to the Jurassic period.
• The Gondwana rock system is one of the oldest geological formations in India, known for its coal deposits and ancient flora and fauna fossils.
• The Rajmahal Hills have significant paleontological importance due to the discovery of plant fossils and dinosaur footprints.

Additional Information

• Gondwana Supercontinent:
  • Gondwana was a supercontinent that existed from the late Precambrian to the Jurassic period.
  • It included regions that are now part of South America, Africa, Antarctica, Australia, and the Indian subcontinent.
• Volcanic Activity:
  • The Rajmahal Traps are the result of extensive volcanic activity that occurred around 118-113 million years ago.
  • This volcanic activity is associated with the breakup of the Gondwana supercontinent.
• Paleontology:
  • The Rajmahal Hills are known for their fossilized flora, including well-preserved plant fossils from the Jurassic period.
  • Fossils of Gymnosperms, Pteridophytes, and other ancient plants have been found in the region.
• Geological Significance:
  • The Gondwana rock system is crucial for understanding the geological history and the tectonic evolution of the Indian subcontinent.
  • It provides valuable insights into past climatic conditions, sedimentation patterns, and the evolution of life on Earth.
