1609 AD marked the beginning of the modern scientific exploration of the Moon's crust when
Thomas Harriot and later Galileo Galilei made the first recorded maps of the nearside with …

Stable potassium isotopes are one of the emerging non-traditional isotope systems enabled
in recent years by the advance of Multi-Collector Inductively-Coupled-Plasma Mass …

Rainwater dissolves urban air contaminants that threaten sustainable urbanization and
human health. Tracing rainwater contamination supports urban management and …

The nine editions of Stable Isotope Geochemistry have appeared over a time span of nearly
50 years. The first edition (1973) appeared as a slim book of 135 pages. Due to the rapid …

Plants play a critical role in the surficial environment, influencing energy transfer, the global
carbon cycle, and climate change. Potassium (K) controls many essential plant physiological …

Mass-dependent K isotopic fractionations can be used to trace cosmochemical, geological,
and biological processes such as evaporation/condensation, core formation, magmatic …

The Moon has a tenuous atmosphere produced by space weathering. The short-lived nature
of the atoms surrounding the Moon necessitates continuous replenishment from lunar …

Volatiles are vital ingredients for a habitable planet. Angrite meteorites sample the most
volatile-depleted planetesimal in the Solar System, particularly for the alkali elements. They …

We report the first zinc isotope data (expressed as δ 66 Zn relative to the JMC-Lyon
standard) for chromian spinels (Cr-spinels) and coexisting olivines in oceanic peridotites. All …

Prevailing models for the formation of the Moon invoke a giant impact between a planetary
embryo and the proto-Earth (Canup, 2004; Ćuk et al., 2016). Despite similarities in the …
