Tabun-Khara-Obo crater
Tabun-Khara-Obo is an impact crater in the Dornogovi Aimag (province) the south-east of Mongolia.[1] The crater, which is exposed at the surface, is 1.3 km in diameter. The crater's rim rises some 20 to 30 meters above the crater bottom.[2] It has an estimated age of 150 ± 20 million years (Upper Jurassic).The site was first identified as a probable impact crater in 1976, although confirmation of the hypothesis only occurred decades later.[2] Drilling at the site in 2008 revealed rock features consistent with high-speed impacts such as those caused by meteorites.[2]
