We reevaluate the systematics and geologic setting of terrestrial, lunar, Martian, and
asteroidal “impactites” resulting from single or multiple impacts. For impactites derived from …

We report results of an interdisciplinary project devoted to the 26 km‐diameter Ries crater
and to the genesis of suevite. Recent laboratory analyses of “crater suevite” occurring within …

Abstract The South Pole–Aitken (SPA) basin is the oldest and largest impact structure on the
Moon, and it gives particular insight on the lunar interior composition,–. However, the …

Highly expanded Cretaceous–Paleogene (K-Pg) boundary section from the Chicxulub peak
ring, recovered by International Ocean Discovery Program (IODP)–International Continental …

More than 50 years of space and planetary exploration and concomitant studies of terrestrial
impact structures have demonstrated that impact cratering has been a fundamental process …

Potentially hazardous asteroids and comets have hit Earth throughout its history, with
catastrophic consequences in the case of the Chicxulub impact. Here we reexamine one of …

Global maps of crustal thickness on the Moon, derived from gravity measurements obtained
by NASA's Gravity Recovery and Interior Laboratory (GRAIL) mission, have shown that the …

We investigated the ejection mechanics by a complementary approach of cratering
experiments, including the microscopic analysis of material sampled from these …

We present a model that describes the formation of melt droplets, melt fragments, and
accretionary impact lapilli during a hypervelocity impact. Using the iSALE hydrocode …

The Moon exhibits striking geological asymmetries in elevation, crustal thickness, and
composition between its nearside and farside. Although several scenarios have been …
