Geology is a very ambivalent belief system.

On the one hand:

The discovery of stishovite at the Kachchh (Luna) site in India has helped convinced some geologists they’re dealing with an meteorite impact even though the dimple doesn’t display the necessary depth to diameter ratio to qualify as a meteorite impact from above.

This site appears to be a unique site in the world, as it lacks the characteristics of a typical impact site. Conventionally measured depth to diameter ratio is dismally low.

X-ray analysis of the materials adhering to meteorite fragments carried out by Dr George Mathew, Earth Science Department, the Indian Institute of Technology Bombay reveal stishovite and coesite, the high pressure polymorphs of sllica, which confirms the impact origin of the crater.
