▪ Abstract The Re-Os isotope sytem, based on the long-lived β− transition of 187Re to
187Os, has matured to wide use in cosmochemistry and high-temperature geochemistry …

Water plays a critical role in erosion and sediment transport and this relationship is most
evident in the hyperarid Atacama Desert of Northern Chile, a region characterized by …

Since the early 1950s, the number of international measurement standards for anchoring
stable isotope delta scales has mushroomed from 3 to more than 30, expanding to more …

Rhenium and osmium concentrations and osmium isotopic ratios of group IIA, IIIA, IVA, and
IVB iron meteorites were determined by negative thermal ionization mass spectrometry with …

Here we describe a new chemical separation method for Os and an improved mass
