The terrestrial impact cratering record
Tectonophysics, 1992Approximately 130 terrestrial hypervelocity impact craters are currently known. Due to variations in preservation and in geologic knowledge, this sample is biased towards young ( x 20 km) craters on the cratons of Australia, Europe (including the former U.S.S.R.) and North America. The rate of discovery of new craters is 3–5 craters per year.

The classic studies of the Barringer Crater, Arizona, Ries Crater, South Germany, and more recently Chicxulub impact structure, Yucatan, and other craters, coupled with laboratory high-velocity impact experiments, have established the dynamics of impact cratering, shock metamorphism and ballistic ejecta processes.

Impact Crater Formation in Rock
Journal of Applied Physics, 1960Craters were produced by firing spherical steel projectiles of 316- and 932−in. diam into sandstone and granite at velocities ranging from 300 to 6000 ft/sec. Impact angles of 30, 60, and 90 deg were used for the sandstone and 90 deg for the granite. The craters are formed by two mechanisms: (a) crushing of material in front of the projectile and (b ...

Structural geology of impact craters
Journal of Structural Geology, 2014Abstract The formation of impact craters is a highly dynamic and complex process that subjects the impacted target rocks to numerous types of deformation mechanisms. Understanding and interpreting these styles of micro-, meso- and macroscale deformation has proved itself challenging for the field of structural geology.

Aerial surveys of the Vredefort impact crater in South Africa suggest that it is only weakly magnetic. The rocks themselves tell a different story, but does this apply to giant impact basins on Mars?

Impact Cratering and Post-impact Sedimentation
2010The impact origin of the Mjolnir structure has been confirmed by detailed studies of lithologies from two shallow boreholes; one close to the crater center (7329/03-U-01) and one 30 km NE from the crater periphery (7430/10-U-01) (Fig. 1.7). The boreholes revealed brecciated sediments containing shocked quartz grains.

A theoretical analysis of cavity depth for impacts of waterdrops against water is made and an equation for cavity depth is derived. Experimental crater-depth data, collected for the purpose of testing the equation, are tabulated. The agreement found is considered good.
