description Tin Bider Overview
Tin Bider is a meteorite impact structure in the Sahara of southern Algeria. It is about six kilometers in diameter and is recognized by a central uplift surrounded by concentric, ring-like geological features produced by the impact. The arid desert setting exposes parts of the structure clearly, allowing field studies of impact deformation, breccia, and the way a crater can be modified after its formation.
help Tin Bider FAQ
Where is the Tin Bider crater?
Tin Bider is in the Sahara of southern Algeria, on dry and rugged desert terrain. The structure is exposed at the surface rather than being completely buried by younger rocks.
How wide is Tin Bider crater?
Tin Bider is about 6 kilometres in diameter. Its central uplift and concentric rings show that it is a complex impact structure.
What formed the Tin Bider structure?
It was formed by a meteorite impact. The collision deformed the surrounding sedimentary rocks and produced the crater's raised centre and ring-like geology.
How old is the Tin Bider impact?
Its age is generally given as less than 70 million years, possibly from the Late Cretaceous or early Tertiary. The exact impact date is not established with the same precision as the crater's diameter.
