Initially, it may seem extremely daunting to be sitting in front of several thousand carats of
small diamonds, knowing that the likelihood of finding a diamond with a meaningful …

As one of the largest Phanerozoic orogens in the world, the Central Asian Orogenic Belt
(CAOB) is a natural laboratory for studies of continental dynamics and metallogenesis. This …

Sulfur belongs among H2O, CO2, and Cl as one of the key volatiles in Earth's chemical
cycles. High oxygen fugacity, sulfur concentration, and δ34S values in volcanic arc rocks …

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

Arc magma acquires continental crust-like trace element signatures through selective
recycling of incompatible elements from the subducted slab. The long-standing model of …

Geofluids (2010) 10, 254–269 Abstract Metamorphism and metasomatism both involve the
reequilibration of mineral assemblages due to changes in pressure, temperature and/or …

Plate tectonic forcing leads to changes in the physical conditions that affect the lithosphere.
In response to such changes, notably the local temperature (T) and pressure (P), rocks …

At subduction zones, oceanic lithosphere that has interacted with sea water is returned to
the mantle, heats up during descent and releases fluids by devolatilization of hydrous …

A ca. 600m-long, 0.5–20m-wide NW–SE trending granite dike crosscuts the high pressure–
low temperature (HP–LT) Tianshan metamorphic belt, the foliation of which is parallel to the …

Recent activity–composition models for clinopyroxene and amphibole are revised to provide
better consistency with observed phase relations in natural rocks. For clinopyroxene, the …
