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 …

The continental crust is the archive of the geological history of the Earth. Only 7% of the crust
is older than 2.5 Ga, and yet significantly more crust was generated before 2.5 Ga than …

Generation of continental crust in collision zones reflect the interplay between oceanic
subduction and continental collision. The Gangdese continental crust in southern Tibet …

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

Continental crust is the archive of Earth history. The spatial and temporal distribution of
Earth's record of rock units and events is heterogeneous; for example, ages of igneous …

Most magmatism on Earth forms by direct melting of the mantle, generating basalts at the
low silica end of the terrestrial compositional spectrum. However, most subduction zone …

This paper presents new major and trace-element data and Lu–Hf and Sm–Nd isotopic
compositions for representative suites of marine sediment samples from 14 drill sites …

The last 15yr have seen an explosion of data on the volatile contents of magmas parental to
arc volcanoes. This has occurred due to the intense study of melt inclusions trapped in …

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 …

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 …
