Nitrogen is an essential nutrient for all life on Earth and it acts as a major control on
biological productivity in the modern ocean. Accurate reconstructions of the evolution of life …

Chemical geodynamics is an integrated discipline that studies the geochemical structure
and tectonic evolution of geospheres with the aim of linking tectonic processes to …

Earth's carbon, derived from planetesimals in the 1 AU region during accretion of the Solar
System, still retains similarities to carbon found in meteorites (Marty et al. 2013) even after …

Volatile elements (water, carbon, nitrogen, sulfur, halogens, and noble gases) played an
essential role in the secular evolution of the solid Earth and emergence of life. Here we …

High-pressure (HP) and ultra-high pressure (UHP) terranes are excellent natural
laboratories to study subduction-zone processes. In this paper we give a brief theoretical …

The interface between subducting oceanic slabs and the hanging wall is a structurally and
lithologically complex region. Chemically disparate lithologies (sedimentary, mafic and …

Phase and melting relations in deeply subducted sediments, the main reservoir of large ion
lithophile elements (LILE) in subduction zones, are of first order importance to understand …

Island arc lavas, erupted above subduction zones, commonly contain a geochemical
component derived from partial melting of subducted sediment. It is debated whether this …

Study of metamorphic suites directly representing the deep subduction of altered oceanic
crust and sediments can help elucidate the geochemical evolution of the forearc-to-subarc …

Abstract Adsorption of ammonium (NH 4+) by clay minerals in soil/sediment and altered
oceanic crust plays an important role in Earth's geological nitrogen cycle by transporting …
