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 …

Potassium isotopic compositions of profiles through saprolites developed on a diabase in
South Carolina, USA, and on a granite in Guangdong, China, allow characterization of the …

In the last a few years, several groups proposed new methods of high-precision K isotope
analysis using Multiple Collector Inductively Coupled Plasma Mass Spectrometer (MC-ICP …

Non-traditional stable isotopes (eg, Li, Mg, and Si) are increasingly used as tracers for
studying Earth's surface processes. The isotopes of potassium (K), a highly soluble and …

The causal effects among uplift, climate, and continental weathering cannot be fully
addressed using presently available geochemical proxies. However, stable potassium (K) …

Oceanic crust and sediments are the primary K sinks for seawater, and they deliver
considerable amounts of K to the mantle via subduction. Historically, these crustal …

Abstract Low-temperature (< 100° C) alteration of oceanic crust plays an important role in
determining the chemical composition of the oceans. Although a major sink of seawater …

Arc magmas derived from mantle melting often have trace element and isotopic signatures
that indicate crustal contributions. The origin and extent of crustal contributions are critical …

In situ Al-silicate formation, also known as “reverse weathering,” is an important sink of many
of the major and minor cations in seawater (eg Mg, K, and Li). However, the importance of …
