Ultramafic soils are in equal parts fascinating and dangerous. Developed on rocks derived
predominately from the Earth's mantle and metamorphosed at the ocean floors, ultramafic …

Despite several decades of investigations, inferences on the timing and nature of collisions
along the Mesozoic–Cenozoic Eurasian margin remain controversial. We assimilate …

The Gangdese belt is dominantly composed of igneous rocks that formed during the
northward subduction of Neo-Tethyan oceanic lithosphere beneath the Lhasa terrane and …

Arc magmas, a major contributor to continental crust growth, are thought to be more oxidized
than mid-ocean ridge basalts as reflected by an enrichment in ferric iron relative to ferrous …

We review igneous experimental data designed to understand fractionation processes in the
roots of magmatic arcs, focusing on fractional crystallization experiments in dry and hydrous …

We review data and recent research on arc composition, focusing on the relatively complete
arc crustal sections in the Jurassic Talkeetna arc (south central Alaska) and the Cretaceous …

Magmatic volatiles (for example, water) are abundant in arc melts and exert fundamental
controls on magma evolution, eruption dynamics and the formation of economic ore …

The Tso Morari serpentinites in the Ladakh area, northwest Himalaya, originated from the
forearc mantle overlying the northward subducting Neo-Tethys lithosphere and the margin of …

The Hongshishan and Pobei mafic–ultramafic complexes outcrop in the Beishan area in the
southernmost Altaids. They consist of olivine gabbros, dunites, and pyroxenites. Zircons from …

Intra-oceanic arc systems (IOASs) represent the oceanic endmember of arc–trench systems
and have been the most important sites of juvenile continental crust formation for as long as …
