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 …

Much work has been undertaken quantifying the abundance of phyllosilicate clay minerals
in soils, sediments and rocks of Earth's crust. However, no detailed global compilation of …

Abstract The Middle Eocene Climatic Optimum (around 40 million years ago) was a roughly
400,000-year-long global warming phase associated with an increase in atmospheric CO2 …

Sedimentary rocks contain a unique record of the evolution of the Earth system. Deciphering
this record requires a robust understanding of the identity, origin, composition, and post …

The sedimentary fluxes controlling potassium (K) budget of the oceans and the isotope
composition of K (δ 41 K) potentially yield valuable information about the global K cycling …

The scarcity of well-preserved and directly dateable sedimentary sequences is a major
impediment to inferring the Earth's paleo-environmental evolution. The authigenic mineral …

Sorption of oxyanions, such as pentavalent vanadium (V (V)), by reactive, poorly crystallized
clay minerals and Fe-(hydr) oxides surfaces significantly contributes to the nutrient and …

Clay mineral authigenesis at continental margins plays an important role in global marine
element cycles. However, despite being increasingly used as tracers for both modern and …

Reactive iron (Fe) oxides in marine sediments may represent a source of bioavailable Fe to
the ocean via reductive dissolution and sedimentary Fe release or can promote organic …

Green marine clays, known as glaucony and verdine facies, are unique iron-rich minerals
typically found in shallow marine sedimentary environments covering large areas of …
