The Geological Survey of India(GSI) has identified two geological heritage sites in the Indian Himalayan Region of India.
Which are the two sites identified by GSI?
The two sites identified by GSI in the Himalayan Region are:
Siwalik Fossil Park
Location: Himachal Pradesh
Description of the Site: The Siwalik Fossil park displays a rich collection of vertebrate fossils recovered from the Siwalik rocks of the area of the Plio-Pleistocene age.
– The deposition of Siwalik sediments took place in the narrow linear depression, called the ‘fore deep‘, which started developing in front of the Himalayas since the inception of its uplift in the middle Miocene.
Stromatolite bearing Dolomite / Limestone of Buxa Formation
Location: Sikkim
Description of the Site: The Geoheritage site at Mamley exposes litho units of Buxa Formation, Daling Group of Proterozoic age. The dolostones are profusely stromatolitic (Precambrian algal structures). This site provides one of the rare examples of early life in Sikkim Himalaya.
What are Geo-heritage Sites?
Geo-heritage refers to the geological features which are inherently or culturally significant offering insight to earth’s evolution or history to earth science or that can be utilized for education.
The Geological Survey of India (GSI) declares geo-heritage sites/ national geological monuments for protection and maintenance.
