Dhala impact structure
Dhala crater (N25°17'59.7" and E78°8'3.1") is a crater formed by an asteroid impact.[1] It is situated in Shivpuri district, Madhya Pradesh India and is the second such crater found in India, after Lonar lake.[2] The diameter of the structure is estimated at 11 km and basement rocks are predominantly composed of granitoids. It is estimated that the impact occurred between 1.6 and 2.5 Ga[3] or about 2,500 million years ago.
Largest in India
Dhala crater is considered as the largest in India as well as between the Mediterranean and Southeast Asia.[2][3] The crater is considered a "large complex impact structure" with an estimated diameter extending up to 25 km.[4] Dhala is the largest impact structure currently known in the region between the Mediterranean and southeast Asia.
