Based on their expedition, the first to this site in almost a century, they were able to find shatter cones and shocked quartz grains, which are rock features only found in impact structures, thus, allowing them to confirm the meteorite impact origin of the crater.

This finding brings the number of known impact craters on Earth to 182.
Because of its preservation state and the shape of the structure, with an inner ring, the Read more…
