Unearthing Ancient Secrets: Jaisalmer’s Link to the Saraswati River
In a fascinating turn of events, new evidence has surfaced linking Jaisalmer, a city in Rajasthan, to the ancient Tethys Sea, which existed over 250 million years ago. This discovery comes from borewell drilling in the Mohangarh area of Jaisalmer, where saline water and marine clay were found deep underground, offering a glimpse into the region's remarkable geological past.
What Was Found?
During the borewell drilling process, a steady flow of saline water erupted for three consecutive days, hinting at the presence of ancient seawater trapped beneath the desert's surface. Alongside this, deposits of fine white clay, typically associated with marine environments, were unearthed.
Why Is This Significant?
These findings align with previous discoveries of marine fossils and shells in the Thar Desert, painting a picture of Jaisalmer as a coastal region millions of years ago. The area, now arid and dry, was once part of the Tethys Sea, a massive ocean that stretched across continents during the Mesozoic Era.
A Window Into Earth’s History
This discovery is more than just a local revelation—it highlights the profound geological shifts that have shaped our planet. Over millions of years, the sea receded, giving rise to the Thar Desert we see today. These remnants of the past remind us of Earth’s dynamic history and the forces of nature that continue to mold its surface.
What’s Next?
Geologists and researchers are eager to study the saline water and clay samples further, which could reveal more about the Tethys Sea's extent and its impact on the region. This knowledge not only enriches our understanding of the Thar Desert but also underscores Rajasthan's importance in India's geological narrative.
