Вихреподобная круговая особенность.
Tin Bider is a multi ring structure approximately 6 km in diameter.
The target rocks are alternating sequences of upper Cretaceous clay and
limestone. Massive continental sandstone of lower Cretaceous is exposed
in the center having been uplifted approximately 500m from normal depth.
Shatter cones were initially reported, but were not officially
documented. Subsequent investigation yielded conically striated
ventifacts created by wind erosion. PDF's have been identified in some
mineral grains, which indicate an impact origin for the structure, as
does the stratigraphic evidence.
There is a distinct lack of allochthonous material, which
suggests that the structure has been eroded to a depth below that of the
original crater floor.
One feature that tends to distinguish Tin Bider from other
terrestrial impact structures is the extreme prominence of ductile
deformation, where brittle deformation is typical for other impacts.
