Tenoumer crater
Tenoumer is an impact crater in Mauritania.[1]
Details
The crater is located in the western Sahara Desert. It is 1.9 km in diameter and the age is estimated to be 21,400 ± 9,700 years placing it in the Pleistocene. [2] [3]
The crater is exposed at the surface. The crater is nearly circular, and the edge of the crater is 110 metres from the base of the crater to the top of the rim.
Tenoumer crater is on a Precambrian peneplain with a thin layer of Pliocene sediments (no older). A volcanic origin is theorized because of the discovery of basalt and rhyodacite outside of the crater basin. The crater is believed to be caused by an impact event due to basement rocks found outside the crater.
