Mantle and Slab Contribution in Arc Magmas ADS Classic is now deprecated. It will be
completely retired in October 2019. This page will automatically redirect to the new ADS …

The central-western Mediterranean area is a key region for understanding the complex
interaction between igneous activity and tectonics. In this review, the specific geochemical …

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

Abstract Porphyry Cu±Mo±Au deposits are commonly associated with intermediate
composition arc-related igneous rocks with high Sr/Y (and La/Yb) ratios, and such rocks are …

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 …

A model is developed for the origin of ultrapotassic melts by melting of veined lithosphere;
the veins are rich in clinopyroxene and mica, whereas the wall-rocks consist principally of …

Abundant high-K calc-alkaline (HKCA) magmatism appears to be post-collisional and often
shifts to shoshonitic or alkaline–peralkaline compositions in the final stages of orogeny. The …

Major and trace element, Sr–Nd–Pb–O isotope and mineral chemical data are presented for
post-collisional ultrapotassic, silicic potassic and high-K calc-alkaline volcanic rocks from …

Metasomatism above subduction zones is an important process that produces
heterogeneous mantle and thus a diversity of igneous rocks. In the Panzhihua district, on the …

Fractionation of some or all of the high field strength elements (HFSE) Nb, Ta, Zr, Hf, and Ti
relative to other trace elements occurs in igneous rocks from convergent margins and in the …
