Mountain building results in high erosion rates and the interaction of rocks with the
atmosphere, water and life. Carbon transfers that result from increased erosion could control …

Soil nutrient depletion threatens global food security and has been seriously underestimated
for potassium (K) and several micronutrients. This is particularly the case for highly …

The early Earth's environment is controversial. Climatic estimates range from hot to glacial,
and inferred marine pH spans strongly alkaline to acidic. Better understanding of early …

Potassium is a major essential plant nutrient that plays a pivotal role in plant physiological
and metabolic processes, and provides resistance against biotic and abiotic stresses. In …

Abstract The Paleocene-Eocene Thermal Maximum (PETM) hyperthermal,~ 56 million years
ago (Ma), is the most dramatic example of abrupt Cenozoic global warming. During the …

The application of mineral phosphate (P) fertilizers leads to an unintended Cd input into
agricultural systems, which might affect soil fertility and quality of crops. The Cd fluxes at …

This study presents lithium (Li) and magnesium (Mg) isotope data from experiments
designed to assess the effects of dissolution of primary phases and the formation of …

The lithium concentration and isotopic composition of two saprolites developed on a granite
and diabase dike from South Carolina have been measured in order to document the …

Geochemists have long recognized a correlation between rates of physical denudation and
chemical weathering. What underlies this correlation? The Critical Zone can be considered …

Ultramafic outcrops could represent up to 3% or more of the terrestrial surface and their
unusual geochemistry makes them a global hotspot for biodiversity. Ultramafic soils are a …
