The extinction of the dinosaurs and around three-quarters of all living species was almost
certainly caused by a large asteroid impact 66 million years ago. Seismic data acquired …

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 …

Numerical modelling of impact cratering has reached a high degree of sophistication;
however, the treatment of porous materials still poses a large problem in hydrocode …

Impact craters have been used as a standard metric for a plethora of planetary applications
for many decades, including age‐dating, geologic map** and stratigraphic relationships …

We have developed a Web‐based program for quickly estimating the regional
environmental consequences of a comet or asteroid impact on Earth (http: www. lpl. arizona …

Over the past couple of decades, it is has become widely recognized that impact cratering is
a ubiquitous geological process that affects all planetary objects with a solid surface. Indeed …

We report on numerical modeling results of postimpact cooling of craters with diameters of
30, 100, and 180 km in an early Martian environment, with and without the presence of …

The number of newly discovered and confirmed impact structures on earth is growing
continuously. In this review paper, the main attributes of 198 confirmed impact structures and …

Impact cratering is one of the most fundamental processes responsible for sha** the
surfaces of solid planetary bodies. One of the principal characteristics of impact events is the …

Unusually large and locally variable carbon isotope excursions coincident with mass
extinctions at the end of the Permian Period (253 Ma) and Guadalupian Epoch (260 Ma) can …
