Dwarka Basin: an ancient haven, PgII

Key Highlights:

• Researchers discovered fossil beds in the Dwarka Basin dating back to the early Miocene epoch.
• 42 species of snails were identified, including four new to science, indicating a warm, nutrient-rich environment.
• Marine archaeologists found submerged pillars and over 120 stone anchors near Dwarka in the 1980s.
• The Gujarat government plans to launch submarine tourism to showcase the submerged structures.

Detailed Insights:

• The Dwarka Basin, located off the coast of Gujarat, is a sedimentary basin in the Kathiawar Peninsula containing marine rocks and fossils.
• The basin's rock layers, such as the Gaj and Dwarka formations, date back to the Miocene epoch (23 million to 5.3 million years ago).
• Geologists study the basin to understand Earth's history, while energy companies explore it for potential oil and gas deposits.
• The Archaeological Survey of India continues to map submerged structures discovered in the 1980s.
• The recent findings are expected to enhance understanding of ancient marine environments and biodiversity in western India.

Scientific/Technical Concepts Involved:

• Miocene Epoch: A geological epoch within the Neogene Period, spanning from 23 to 5.3 million years ago.
• Sedimentary Basin: A depression in the Earth's crust where sediments accumulate over time.
• Marine Fossils: Preserved remains of ancient marine life found in sedimentary rocks.
