The '''Dhala impact structure''' (N25°17'59.7" and E78°8'3.1") is an impact structure formed by an asteroid impact.<ref>{{cite Earth Impact DB | name = Dhala| linkname = dhala| accessdate = 2016-04-26}}</ref> It is situated near Bhonti village in Pichhore block of [[Shivpuri district]] of [[Madhya Pradesh]] state in [[India]].<ref name=mint/> It is the largest impact structure in India,<ref name=mint/> and between the Mediterranean and Southeast Asia. The diameter of the structure is estimated at {{convert|3|km}},<ref>{{Cite web|url=https://www.lpi.usra.edu/meteor/metbull.php?code=49717|title=Meteoritical Bulletin: Entry for Dhala|website=www.lpi.usra.edu|access-date=2020-01-24}}</ref> while other sources estimate its diameter to be 11 km diameter. It is the second such structure found in India, after [[Lonar lake]].<ref name=mint>{{cite news|last1=PTI|title=Indian geologist discovers oldest impact structure in India|url=http://www.livemint.com/Industry/uMSLhf2ryC7wyH0qbJtBrI/Indian-geologist-discovers-oldest-impact-structure-in-India.html|accessdate=26 July 2015|publisher=Live Mint, News|date=11 January 2009}}</ref>

It is 200 km east of the [[Ramgarh crater]].

==Impact date ==

It is estimated that the impact occurred between 2.44 and 2.24 Ga.<ref>{{cite journal |doi=10.1016/j.gr.2017.10.006 |title=Anatomy of impactites and shocked zircon grains from Dhala reveals Paleoproterozoic meteorite impact in the Archean basement rocks of Central India |journal=Gondwana Research |volume=54 |pages=81–101 |year=2018 |last1=Li |first1=Shan-Shan |last2=Keerthy |first2=S |last3=Santosh |first3=M |last4=Singh |first4=S.P |last5=Deering |first5=C.D |last6=Satyanarayanan |first6=M |last7=Praveen |first7=M.N |last8=Aneeshkumar |first8=V |last9=Indu |first9=G.K |last10=Anilkumar |first10=Y |last11=Sajinkumar |first11=K.S |bibcode=2018GondR..54...81L }}</ref> Basement rocks are predominantly composed of [[granitoids]].
