Kgagodi crater

Kgagodi is an exposed meteorite crater in Botswana, roughly 7 kilometres south of the village of Kgagodi, where it got its name.
It is 3.5 km in diameter and the age is roughly less than 180 million years. It is estimated to be from the late Cretaceous to early Tertiary Period. The crater is best known for being Botswana’s first recognised impact structure.
History.
The Kgagodi crater first came to attention in 1997, when a Botswana water-drilling expedition came across an elliptical-shaped structure. It was filled with sediment. The Geological Survey of Botswana then drilled a core sample that was 274 meters deep. The core sample suggested that it may be an impact structure, but there was no definite evidence for it. It was during another study of the structure that yielded the answer. Impact breccia were soon discovered, confirming Kgagodi as an impact crater.
