Rajasthan: Former underwater site transformed into tourist site | Udaipur News

UDAIPUR: About 80 crore years ago, this place was a sea. The remains found here called stromatolites are known as the impression of one of the earliest forms of life on earth.
Stromatolites consumed carbon dioxide from the atmosphere, which was then rich in CO2, and released oxygen which enriched the atmosphere with vital oxygen.
The Bojunda Stromatolite Fossil Park near Chittorgarh is an exhibit in the Bhagwanpura Limestone Massif from the Vindhyan Age. In 1976, the Geological Survey of India included the site among the lists of national geological monuments and there are 12 geoheritage sites in Rajasthan.
Since then, this site has been forgotten, but thanks to the initiative taken by the Department of Mines and Geology in association with the Chittorgarh district administration, it is proposed to develop a geopark on this forgotten site. . A team of experts and authorities including Pradeep Agarwal, Additional Director, Mines and Geology and collector Tarachand Meena and others recently visited the site. Meena ordered to complete the mapping of the area and led a proposal for a geopark in a 12 hectare area here.
“Bojunda Geopark has great potential to become a popular destination for Mewar Tour tourists, but it needs to be properly promoted by the State and Union Ministries of Tourism. Due to its favorable location and a welcome variation from a routine tourist site, this destination would be a welcome ‘satellite site’ for tourists and visiting students, ”said Prof. PS Ranawat, expert and advisor. in geo-heritage.
Ranawat submitted a development plan as part of phase 1 which includes a perimeter wall, walkway and parking area. “An interpretation center with a hall and a small office for an indoor museum and an audiovisual exhibition and wall images and 3D models placed on the ground on the various geodiversities of this district is proposed.
A large-screen television or display system and an installation of about 50 seats for viewing video clips will also be present in this integrated circuit. The display facility will showcase representative samples of Chittorgarh’s georesources, viz. limestones, sandstones, schists, clays, red ocher. Maps of the region’s georesources, industries based on them (foundry, cement factories, collective saws), their impact on the economy and society should be installed, ”said Ranawat.
What are stromatolites?
Stromatolites are structures produced by blue-green algae which, thanks to their filaments, attract and bind carbonate particles, forming a mat. They are mostly columnar structures perpendicular to horizontal carbonate rocks resulting from the combination of vital activity and sediment entrapment and the binding capacity of algal assemblages and prey bacteria.
They generally form in an intratidal regime (shallow water) where the tides continuously bring floating sedimentary materials and cause them to flow through the carbonate particles. India’s Vindhyan group of rocks is one of the largest and thickest sedimentary rock sequences in the world, which was deposited in an intracratonic basin, it is composed mostly of shallow marine deposits.
It is believed to have recorded a significant portion of the past 1,000 million years of Earth’s history and therefore contains valuable information on the evolution of the atmosphere (CO2-rich to O2-rich), climate and life on our planet (single-celled marine life).
