India’s Geological Treasures: Lonar Lake and St. Mary’s Island

India’s Geological Treasures: Lonar Lake and St. Mary’s Island

In a remarkable initiative by the Geological Survey of India (GSI), two of India’s geological wonders are on the verge of achieving global recognition as UNESCO Global Geoparks. This move aims to spotlight Lonar Lake in Maharashtra and the duo of St. Mary’s Island and Malpe beach in coastal Karnataka, underscoring India’s rich geological heritage on an international scale.

St. Mary’s Island: A Geological Marvel

• Geological Significance: St. Mary’s Island is renowned for its stunning hexagonal basaltic rock formations, which are approximately 88 million years old. These formations provide a fascinating glimpse into the period when Greater India separated from Madagascar, offering insights into the Earth’s evolutionary journey.
• Heritage Recognition: Declared a national geo-heritage site in 1975, St. Mary’s Island stands as a remarkable witness to India’s ancient geological lineage, preserved through the ages.

Lonar Lake: A Crater of Cosmic Origin

• Unique Formation: Lonar Lake is the result of a meteorite impact on basaltic rock approximately 50,000 years ago, and it is noted for its near-perfect circular form. It remains the only known meteorite crater in basaltic rock globally, marking it as a site of significant geological interest.
• Heritage Designation: Designated as a geo-heritage site in 1979, the Lonar Crater has captivated scientists and tourists with its intriguing origins and unique geological characteristics.

Path to Global Recognition

The journey to being included in the UNESCO Global Geopark Network involves meeting stringent criteria, such as developing a dedicated website, creating a comprehensive management plan, implementing protection strategies, and establishing financial and partnership structures. In August, the GSI embarked on this process with a 100-day timeline to advance its plan.

Significance of the Geopark Tag

Achieving UNESCO Global Geopark status would not only emphasize the geological significance of these sites but also promote them as centers for education and eco-tourism. This designation is akin to the prestige of a ‘World Heritage Site’ but focuses on natural landmarks, elevating India’s geological marvels to an international platform.

Through this endeavor, the GSI highlights the importance of preserving and celebrating India’s geodiversity, aiming to bring these natural wonders to global attention and conservation efforts. Securing the recognition of Lonar Lake and St. Mary’s Island as UNESCO Global Geoparks would be a significant milestone in India’s dedication to its geological heritage, enriching both scientific understanding and public appreciation for these extraordinary natural phenomena.
