Logoisk - Hypervelocity Impact Crater

Alternate Names N/A
Coordinates 54° 12' 4" N; 27° 47' 45" E
Notes
  1. 8 km NW of the city of Logoisk.
Country Belarus
Region Minsk
Date Confirmed 1979
Notes
  1. Confirmed by presence of shatter cones in granite-gneisses and dolomites and planar deformation in coesite and stishovite (Veretennikov et al., 1979).
Buried? Yes
Notes
  1. 400-500 m of Oligocene-Miocene and Late Quaternary sediments comprise the filling and covering complexes (Masaitis et al., 1980).
Drilled? Yes
Notes
  1. About 20 boreholes, each reaching depths of ~ 500 m, penetrate sedimentary cover and fill, allogenic breccia and fractured basement complex (Masaitis et al., 1980).
Target Type Mixed
Notes
  1. Middle Devonian dolomite and Cretaceous sandstone and Archean - Lower Proterozoic gneisses and Vendian sandstones and claystones (Masaitis et al., 1980).
Sub-Type Claystone, Dolomite, Gneiss, Sandstone
Apparent Crater Diameter (km) 17 km
Age (Ma) 30.0 ± 0.5
Notes :
  1. 40Ar/39Ar of impact glass provides an age of 30 ± 0.5 Ma (Sherlock et al., 2006). Additional age constraints: Previously dated as 40 ± 5 Ma by stratigraphy, based on being apparently formed in Late Cretaceous times (Masaitis et al., 1980).

Method :
  1. 40Ar/39Ar
Impactor Type Unknown

  1. Drilling indicates the presence of a central uplift comprising brecciated Precambrian gneisses. From the cross section in Veretennikov (2010) the central uplift appears to be completely covered by allochthonous crater-fill impactites and so does not appear to be emergent. In contrast, a cross-section in Masaitis (1999) suggests the presence of a small central peak with SU 200 m.

Crater Fill

  1. Volume of melt via Table 1 in (Grieve and Cintala, 1992). Crater-fill impactites include monomict and polymict lithic breccias, made up of fragments of target rocks, melt-bearing breccias (referred to as suevites) with different amounts of glass, and melt rocks as lenses (referred to as tagamites) with a glassy matrix (Masaitis, 1999) (Sherlock et al., 2009). Lithic breccias can also be found as proximal ejecta in the western sector outside the crater.
