In the past few years, several major space missions have been completed (eg, Deep Impact,
LCROSS, Chandrayaan-1, Stardust, Hayabusa), and a number of spacecraft are currently …

The bulk chemical compositions of planets are uncertain, even for major elements such as
Mg and Si. This is due to the fact that the samples available for study all originate from …

Shock metamorphism of minerals in meteorites provides insights into the ancient Solar
System. Calcite is an abundant aqueous alteration mineral in carbonaceous chondrites …

Abstract Knowledge of the shock behavior of planetary materials is essential to interpret
shock metamorphism documented in rocks at hypervelocity impact structures on Earth, in …

An accurate understanding of the relationship between the impact conditions and the
degree of shock‐induced thermal metamorphism in meteorites allows the impact …

Cyanide compounds are amongst the most important molecules of the origin of life. Here, we
demonstrate the importance of mid-size (0.1–1 km in diameter) hence frequent meteoritic …

Two impact cratering experiments on nonporous rock targets were carried out to determine
the influence of target composition on the structural mechanisms of subsurface deformation …

Carbonate minerals, for example calcite and magnesite, exist on the planetary surfaces of
the Earth, Mars, and Venus, and are subjected to hypervelocity collisions. The physical …

We simulated entrainment of carbonates (calcite, dolomite) in silicate impact melts by 1‐bar
laser melting of silicate–carbonate composite targets, using sandstone, basalt, calcite …

Hypervelocity bolide impacts deliver vast amounts of energy to the Earth's near surface. This
crustal process almost universally includes sedimentary target rocks; however, their …
