Rock weathering is a key component of the rock cycle that transforms rocks in sediments,
soils and/or dissolves minerals to ions, and plays an important role in landforms …

Soil supports life by serving as a living, breathing fabric that connects the atmosphere to the
Earth's crust. The study of soil science and pedology, or the study of soil in the natural …

A negative feedback between silicate weathering rates and climate is hypothesized to play a
central role in moderating atmospheric CO 2 concentrations on geologic timescales …

Magnesium (Mg) stable isotopes are increasingly used as a weathering proxy in soils and
rivers, but the impact of the mineralogy of secondary phases on isotope fractionation …

To better constrain Li dynamics in the tropics, we sampled critical zone compartments of a
small forested andesitic catchment in Guadeloupe (soils, parent rock, atmospheric dust …

Landscape curvature evolves in response to physical, chemical, and biological influences
that cannot yet be quantified in models. Nonetheless, the simplest models predict the …

The results of the GEOTREF project presented here aim to develop high enthalpy
geothermal energy in fractured reservoirs. They focus on active volcanic islands, especially …

Silicate weathering–initiated by major mineralogical transformations at the base of ten
meters of clay-rich saprolite–generates the exceptionally low weathering flux found in …

Volcanic systems often host crater lakes, flank aquifers, or fumarole fields that are strongly
acidic. In order to explore the evolution of the physical and mechanical properties of an …

The Perseverance rover has sampled mm‐size lithic fragments containing olivine likely from
at least two source regions from the surface of an inactive megaripple surface, and fine …
