Metals such as Cu, Mo, Au, Sn, and W in porphyry and related epithermal mineral deposits
are derived predominantly from the associated magmas, via magmatic–hydrothermal fluids …

Ubiquitous heterogeneity in the Earth's mantle has been documented by numerous
chemical and isotopic analyses of oceanic basalts. Despite the ever-increasing amount of …

Crustal recycling at convergent plate boundaries is essential to mantle heterogeneity.
However, crustal signatures in the mantle source of basaltic rocks above subduction zones …

We present a comprehensive geochemical data set for the most recent volcanics from the
Mariana Islands, which provides new constraints on the timing and nature of fluxes from the …

Abstract Porphyry Cu-(Mo-Au) deposits are relatively rare but reproducible products of
subduction-related magmatism. No unique processes appear to be required for their …

Rutile is the most common naturally occurring titanium dioxide polymorph and is widely
distributed as an accessory mineral in metamorphic rocks ranging from greenschist to …

Based on a compilation of published sources, rocks referred to as adakites show the
following geochemical and isotopic characteristics: SiO2≥ 56 wt percent, Al2O3≥ 15 wt …

A new ICP‐MS database for glasses from the Mariana Trough, together with published and
new ICP‐MS data from the Mariana arc, provides the basis for geochemical mapping of the …

The Middle–Lower Yangtze River Valley metallogenic belt (YRB), situated along the
northern margin of the Yangtze craton, is characterized by porphyry–skarn–stratabound Cu …

Geochemical tracers demonstrate that elements are cycled from subducted sediments into
the arc melting regime at subduction zones, although the transfer mechanism is poorly …
