Beyenchime-Salaatin - Hypervelocity Impact Crater

Alternate Names N/A
Coordinates 71° 3' 38" N; 121° 41' 13" E
Notes
  1. On the upper reaches of the Beyenchime-Salaatin River, E of the Popigai crater.
Country Russia
Region Sakha
Date Confirmed 1975
Notes
  1. Primary evidence was the discovery of shatter cones in dolomite (Masaitis, 1975).
Buried? No
Notes
  1. Unconsolidated Holocene and Upper Quaternary deposits are widespread within the basin (Mikhaylov et al., 1979).
Drilled? No
Target Type Sedimentary
Notes
  1. Cambrian to Permian siltstones, sandstones and limestones overlying late Proterozoic carbonate rocks (Mikhaylov et al., 1979).
Sub-Type Carbonate, Limestone, Sandstone, Siltstone
Apparent Crater Diameter (km) 8 km
Age (Ma) 1.8 - 66
Notes :
  1. Permian clasts are found within the breccia, so the age is post-Permian (Cenozoic?) (Masaitis, 1999). The erosion is comparable to Popigai so (Mikhaylov et al., 1979) estimate it as Neogene (1.8 to 22.5 Ma).

Method :
  1. Stratigraphy
Impactor Type Unknown

  1. Cross-sections drawn as simple crater. A circular basin is surrounded by a concentric ridge of Cambrian rocks, which ranges in width from 1.5 to 2.5 km, all surrounded by a centrifugal pattern of thrusts and radial faults (Mikhaylov et al., 1979). The crater interior comprises a “flat depression” with “isolated hills” of allochthonous crater-fill impactites (Masaitis, 1999). There is no evidence for a central uplift.

Shatter Cones
Yes
  1. Shatter cones occur in the southeastern part of the crater, on the ridge, in limestone (of the Kuonamka suite), ranging in length from several to ten centimeters (Mikhaylov et al., 1979). Well-developed shatter cones occur in dolomites from the annular swell (Masaitis, 1975). Shatter cones clasts in impact breccia occur (Masaitis, 1999).
