Chemical geodynamics of mafic magmatism above subduction zones
The geochemical signatures of subducting crust have been identified in various types of
mafic igneous rocks at convergent plate boundaries, where island arc basalts (IAB) and …

Subduction erosion and arc volcanism
Tectonic or subduction erosion refers to the removal of upper-plate material from the forearc
at convergent margins. Subduction erosion has been suggested to represent a major …

The role of subduction erosion in the generation of Andean and other convergent plate boundary arc magmas, the continental crust and mantle
CR Stern - Gondwana Research, 2020 - Elsevier
Subduction erosion, which occurs at all convergent plate boundaries associated with
magmatic arcs formed on crystalline forearc basement, is an important process for chemical …

Appinite suites and their genetic relationship with coeval voluminous granitoid batholiths
JB Murphy - International Geology Review, 2020 - Taylor & Francis
Appinite complexes preserve evidence of mantle processes that produce voluminous
granitoid batholiths. These plutonic complexes range from ultramafic to felsic in composition …

Volatiles in subduction zone magmatism
The volatile cycle at subduction zones is key to the petrogenesis, transport, storage and
eruption of arc magmas. Volatiles control the flux of slab components into the mantle wedge …

Multiple episodes of rock-melt reaction at the slab-mantle Interface: formation of high silica primary magmas in intermediate to hot subduction zones
Siliceous slab-derived partial melts infiltrate the sub-arc mantle and cause rock-melt
reactions, which govern the formation of diverse primary arc magmas and lithological …

Geochemical and petrological insights into the tectonic origin of the Transmexican Volcanic Belt
A Gómez-Tuena, L Mori, SM Straub - Earth-Science Reviews, 2018 - Elsevier
Abstract The Transmexican Volcanic Belt (TMVB) is the magmatic expression of one of the

Crustal recycling by subduction erosion in the central Mexican Volcanic Belt
Recycling of upper plate crust in subduction zones, or 'subduction erosion', is a major
mechanism of crustal destruction at convergent margins. However, assessing the impact of …

Geochronology and geochemical characteristics of Late Triassic porphyritic rocks from the Zhongdian arc, eastern Tibet, and their tectonic and metallogenic …
JL Chen, JF Xu, JB Ren, XX Huang, BD Wang - Gondwana Research, 2014 - Elsevier
Ore-bearing porphyritic rocks are widely distributed in the Zhongdian arc in the southern part
of the Yidun arc, eastern Tibet. New U–Pb zircon dates, and previous results, show that the …
