Terrestrial ages of meteorites from the Atacama Desert (Chile) and insights into the past meteorite flux to Earth

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract The Atacama Desert in Chile is characterized by its high meteorite density and old meteorite terrestrial ages. In this work, we present new terrestrial ages derived from measurements of the concentration of cosmogenic 36Cl in the metal fraction of 51 ordinary chondrites collected over a 6.8 km2 area located in the Catalina Dense Collection ...

Microbial Endolithic Community at Meteor Crater

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Postimpact recovery and evolution in response to climate changes produced a modern ecosystem at Meteor Crater dominated by a grassland and woodland of piñon and juniper, which has been used to evaluate floral and megafaunal consequences of impact cratering during the Phanerozoic Eon of complex life.

Non‐innocent solvents in meteorite extractions: Evidence for artifact formation

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Solvent extraction is a cornerstone of meteoritic organic and inorganic chemistry, yet the assumption that common solvents act as chemically inert media is becoming increasingly untenable. This study reports that low‐molecular‐weight alcohols, particularly methanol and ethanol, are “non‐innocent” solvents when used to extract soluble sulfur ...
