Abstract We studied three lithologies (light and dark chondritic and impact melt rock) differing in shock stage from the LL5 chondrite Chelyabinsk. Using the 40Ar‐39Ar dating technique, we identified low‐ and high‐temperature reservoirs within all samples, asc…

Abstract Recycling of material at subduction zones has fundamental implications for melt composition and mantle rheology. Ocean island basalts (OIBs) sample parts of the mantle from variable depths that have been diversely affected by subduction zone processes…

Abstract No meteorites from Mercury and Venus have been conclusively identified so far. In this study, we develop an original approach based on extensive Monte Carlo simulations and diffusion models to explore the radiogenic argon (40Ar*) and helium (4He*) los…

Abstract– The isotope fractionation of Zn in meteorites has been measured for the first time using thermal ionization mass spectrometry and a double spiking technique. The magnitude of δZn ranged from −0.29 to +0.38‰ amu−1 for five stone meteorites whereas the…

Certain microorganisms survive long periods of time as endospores to cope with adverse conditions. Since endospores are metabolically inactive, the extent of aspartic acid (Asp) racemization will increase over time and might kill the spores by preventing their…

Over the last years, perennial ice deposits located within caves have awakened interest as places to study microbial communities since they represent unique cryospheric archives of climate change. Since the beginning of the twentieth century, the temperature h…
