Deeply exhumed impact structures: A case study of the Vredefort structure, South Africa,se in temperature to between 700 and 900 °C. Pressure estimates of 0.2–0.3 GPa obtained from these mineral parageneses indicate that the Vredefort structure has been eroded by between 7 and 10 km. The original depth of burial of these rocks after the impact and their elevated temperatures explain th

Identification of ancient impact structures: Low-angle faults and related geological features of crr modification when the steep rim of the transient crater cavity starts to collapse. Gravity-driven sliding occurs in acoustically-fluidized rocks with low cohesion and reduced friction coefficients. It is suggested that the degree of fluidization changes with depth and distance from the impact cent

,Neugrund structure — the newly discovered submarine early Cambrian impact crater,lt of the impact of an extraterrestrial body with a diameter of ca. 400 m. As a consequence of the impact a crater with the rim-to-rim diameter of 7 km was formed. The depth of the ca. 5 km-diameter crater has not yet been determined, but is assumed to range over 500 m. At the distance of about 10 k

Towards a Road Map for Machine Translation Researchysis can only be tentative and partial. First of all it is based on only three conferences, and secondly it does not cover an aspect of MT that is at least as important as developments in research: the MT market.
