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 …

▪ Abstract The detailed morphology of impact craters is now believed to be mainly caused by
the collapse of a geometrically simple, bowl-shaped “transient crater.” The transient crater …

The cause of the end-Cretaceous mass extinction is vigorously debated, owing to the
occurrence of a very large bolide impact and flood basalt volcanism near the boundary …

This handbook of Shock-Metamorphic Effects in Terrestrial Meteorite Impact Structures
emphasizes terrestrial impact structures, field geology, and particularly the recognition and …

The Yucatán Peninsula karst aquifer is one of the most extensive and spectacular karst
aquifer systems on the planet. This transboundary aquifer system extends over an area of …

▪ Abstract The Chicxulub crater ejecta stratigraphy is reviewed, in the context of the
stratigraphy of underlying and overlying rock sequences. The ejecta sequence is regionally …

Ancient ice ages are revealed by distinctive stratal facies that tell us much about the times of
coolness and how the climate system works. Several strong ice ages were recorded in the …

Large impacts provide a mechanism for resurfacing planets through mixing near-surface
rocks with deeper material. Central peaks are formed from the dynamic uplift of rocks during …

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 …

Based on groundwater geochemistry, stratigraphy, and surficial and tectonic characteristics,
the northern Yucatan Peninsula, Mexico, a possible analog for ancient carbonate platforms …
