The dimensions of large craters formed by impact are controlled to a large extent by gravity, whereas the volume of impact melt created during the same event...
Hypervelocity impact involves the near instantaneous transfer of considerable energy from the impactor to a spatially limited near-surface volume of the target...
The terrestrial impact record contains currently ~145 structures and includes the morphological crater types observed on the other terrestrial planets. It has,...
Like concentrations of economic resources, terrestrial impact structures are the result of relatively rare geologic events. Economic resources occur in a...
It has been known for some time that the volume of impact melt (Vm) relative to that of the transient cavity (Vtc) increases with the magnitude of the impact...
The ~7.5 km diameter Wanapitei impact structure (46°45'N; 80°45'W) lies entirely within Lake Wanapitei in central Ontario, Canada. Impact lithologies are known...
Quartz grains separated from the Cretaceous-Tertiary (K/T) boundary clay at Scollard Canyon, Alberta, have prominent, microscopic planar features. These occur...
