Hyderabad: The Geological Survey of India (GSI) has recently identified two geological heritage sites in the Indian Himalayan region of India. Learn more about geoheritage sites and how they promote tourism.

The sites identified are Siwalik Fossil Park, Himachal Pradesh and Stromatolite bearing Dolomite / Buxa Formation Limestone of the Buxa Formation, Sikkim. With the inclusion of these two sites, there are 34 geological heritage sites in India. Earlier, the GSI identified some geological sites across the Northeast for the promotion of geo-tourism.

What are geoheritage sites

Geo-heritage refers to geologic features that are inherently or culturally significant that offer insight into Earth’s evolution or history to earth sciences or that can be used for educational purposes.

The Geological Survey of India (GSI) is the parent body which endeavors to identify and protect the geoheritage sites/national geological monuments of the country.

New geoheritage sites

Siwalik Fossil Park (Himachal Pradesh): Siwalik Fossil Park features a rich collection of vertebrate fossils recovered from Siwalik rocks of the Plio-Pleistocene age region (2.6 million to 11,700 years ago).

Siwalik Fossil Park, Himachal Pradesh.

The deposition of the Siwalik sediments took place in the narrow linear depression, called the “fore-deep”, which began to develop in front of the Himalayas since the beginning of its uplift in the Middle Miocene (23 million years ago). years to 2.6 million years).

Stromatolite bearing Dolomite / Limestone of the Buxa Formation of the Buxa Formation (Sikkim): This geoheritage site in Mamley exposes lithounites of the Buxa Formation, Daling Group of Proterozoic age (2.5 billion years ago). years to 541 million years).

The dolomites (sedimentary rock) are abundantly stromatolitic (Precambrian algal structures). This site provides one of the few examples of primitive life in the Sikkim Himalayas. The Precambrian is the oldest of the geological ages, which are marked by different layers of sedimentary rocks.

UNESCO Global Geoparks

They are unique and unified geographical areas where sites and landscapes of international geological significance are managed with a holistic concept of protection, education and sustainable development.

While there are 169 UNESCO Global Geoparks spread across 44 countries, India does not yet have one.
