A major tool in the initial recognition and study of terrestrial impact craters,∼ 20% of which
are buried beneath postimpact sediments, is geophysics. The general geophysical character …

A survey of published descriptions of 32 of the largest, least eroded terrestrial impact
structures reveals that the amount of melt at craters in crystalline rocks is approximately 2 …

A new non-contact and non-destructive optical scanning instrument provided a large
number of high-precision measurements of thermal conductivity tensor components in …

The Ries Crater, an impact structure of 26 km diameter in south Germany, is the largest
terrestrial crater where substantial amounts of ejecta are preserved, on occasion> 100 m …

Analytical descriptions of crater growth and numerical calculations of aerodynamic drag
have been combined to evaluate the possible effects of drag on impact crater ejecta …

Planar impact experiments were employed to induce dynamic tensile failure in Bedford
limestone. Rock discs were impacted with aluminum and polymethyl methacralate flyer …

The formation, cooling, and alteration of the impact ejecta deposits at the Ries crater are an
analog for impact processes and the formation of regoliths and soils on Mars. We have …

Consideration of the partial pressure of H2O in the Martian atmosphere and the range of
mean annual temperatures at the Martian surface suggests that the occurrence of ground ice …

The Chicxulub crater is an∼ 180‐km‐diameter peak‐ring crater based on drill hole logs and
samples, potential fields, seismic reflection profiles, and surface fracture patterns. A …

Samples from the North Ray crater ejecta blanket, Apollo 16, were investigated by
petrographic microscope, electron microprobe, instrumental neutron activation and Xray …
