An accurate understanding of the relationship between the impact conditions and the degree of shock‐induced thermal metamorphism in meteorites allows the impact environment in the early Solar System to be understood. A recent hydrocode has revealed that impact heating is much higher than previously thought. This is because plastic deformation of the shocked rocks causes further heating during decompression, which is termed post‐shock heating. Here we compare impact simulations with laboratory… 
Reevaluating Links Between Meteorite Impacts and Early Cenozoic Global Warming
The Paleocene‐Eocene Thermal Maximum (PETM) and the lower Chron 29n hyperthermal event were recently proposed to have been triggered by the meteorite impacts that formed the Marquez Dome (Texas, USA;
Shock Recovery With Decaying Compressive Pulses: Shock Effects in Calcite (CaCO3) Around the Hugoniot Elastic Limit
Shock metamorphism of minerals in meteorites provides insights into the ancient Solar System. Calcite is an abundant aqueous alteration mineral in carbonaceous chondrites. Return samples from the
Ryugu’s observed volatile loss did not arise from impact heating alone
Carbonaceous asteroids, including Ryugu and Bennu, which have been explored by the Hayabusa2 and OSIRIS-REx missions, were probably important carriers of volatiles to the inner Solar System. However,

Abstract : The equation of state presented in this report has the same basic format for all metals and differs among the various metals only by choice of numerical constants. For compressed material,
Melt Production in Oblique Impacts
Abstract Hydrocode modeling is a fundamental tool for the study of melt production in planetary impact events. Until recently, however, numerical modeling of impacts for melt production studies has
Slow Impacts on Strong Targets Bring on the Heat
An important new paper by Kurosawa and Genda (2017, https://doi.org/10.1002/2017GL076285) reports a previously overlooked source of heating in low velocity meteorite impacts. Plastic deformation of

Abstract— The thermodynamic properties of SiO2 are approximated over a range of pressures and temperatures important under the extreme conditions achieved in impacts at typical solar system
Effects of Friction and Plastic Deformation in Shock‐Comminuted Damaged Rocks on Impact Heating
Hypervelocity impacts cause significant heating of planetary bodies. Such events are recorded by a reset of 40Ar‐36Ar ages and/or impact melts. Here we investigate the influence of friction and
Evaluation of dehydration mechanism during heating of hydrous asteroids based on mineralogical and chemical analysis of naturally and experimentally heated CM chondrites
Based on the evidence derived from spectroscopic observation and meteorite analysis, some hydrous asteroids were heated and dehydrated for a certain period of time after aqueous alteration. In order
