♦ The hill area around the historic Kalinjar Fort in Banda district has been declared a National Geo-Heritage Site by the Geological Survey of India (GSI). The recognition highlights the region’s rare geological formation known as the Eparchaean Unconformity, which records a long gap in Earth’s geological history. The hill exposes nearly 2.5 billion year old Bundelkhand granite overlain by 1.2 billion year old Kaimur sandstone, making it an important record of Earth’s evolution. Experts said the natural rock formations also played a role in providing strategic defence to ancient rulers who built the fort.

♦ GSI has installed a special information board at the site to explain the geological importance of the formation and raise awareness among visitors.
