India, with its vast and diverse geographical expanse, is home to numerous National Geo-heritage Sites recognized for their exceptional geological features. These sites, spread across the nation, showcase significant geological phenomena such as unique rock formations, fossil records, and geomorphological features. The Geological Survey of India (GSI) plays a crucial role in identifying and preserving these sites for their scientific, educational, and aesthetic values.
Below are some of the notable National Geo-heritage Sites across India:
This saline soda lake was formed by a meteorite impact during the Pleistocene Epoch. It stands out as the only hypervelocity impact crater in basaltic rock anywhere on Earth.
Famous for their columnar basaltic lava formations, these islands off the coast of Karnataka provide insights into volcanic activity and continental drift. The hexagonal mosaic of rocks is believed to have formed due to sub-aerial subvolcanic activity around 88 million years ago.
Located near Visakhapatnam, these rare red sand dunes have formed over thousands of years and are recognized for their geological significance and stunning landscape.
This significant geological structure marks a major fault line between different geological formations and offers insight into the tectonic history of the region.
Several fossil parks, including the Shivalik Fossil Park in Himachal Pradesh and the Ghughua Fossil Park in Madhya Pradesh, preserve extensive fossil records that shed light on prehistoric life and environmental conditions.
In addition to its religious significance, Amarnath Cave is well-known for its stalagmite formation of ice resembling the Shiva Linga, attracting both pilgrims and geologists alike.
These deposits are notable for their high-grade iron ore, offering valuable insights into metamorphic processes and the conditions that create such ores.
This area is recognized for its volcanic formations and fossilized remains, providing evidence of ancient ecosystems and contributing to studies on Deccan volcanism.
Home to India’s only active volcano, Barren Island offers a live laboratory for volcanologists and geologists to study active volcanic processes.
These sites not only enrich our understanding of Earth’s geological history but also serve as natural laboratories for educational and research purposes. Protecting and preserving these geo-heritage sites is essential for maintaining India’s rich geological legacy.
