'''Dhala crater''' (N25°17'59.7" and E78°8'3.1") is situated in [[Shivpuri district]], [[Madhya Pradesh]] State, [[India]]. Currently, the diameter of the structure is estimated at 11 km based on field observations. The basement rocks are predominantly composed of [[granitoids]], and in the centralmost part of the structure voluminous [[melt breccia]] |

containing target rock clasts with shock metamorphic features are directly overlain by a post-impact siltstone- shale-sandstone sequence of the [[Vindhyan Supergroup]]. Recent geochronological dates suggest that the age of the impact event lies in the range between 1.6 and 2.5 Ga. |

The Dhala impact structure (N25°17'59.7" and E78°8'3.1") is an impact structure formed by an asteroid impact.[1] It is situated near Bhonti village in Pichhore block of Shivpuri district of Madhya Pradesh state in India.[2] It is the largest impact structure in India,[2] and between the Mediterranean and Southeast Asia. The diameter of the structure is estimated at 3 kilometres (1.9 mi),[3] while other sources estimate its diameter to be 11 km diameter. It is the second such structure found in India, after Lonar lake.[2]
It is 200 km east of the Ramgarh crater.
Impact date
[edit]It is estimated that the impact occurred between 2.44 and 2.24 Ga.[4] Basement rocks are predominantly composed of granitoids.
Largest in India
[edit]This impact structure on the Bundelkhand craton is the largest in India.[2][5]
