Magmatic to hydrothermal metal fluxes in convergent and collided margins

JP Richards - Ore Geology Reviews, 2011‏ - Elsevier
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 …

Arc magmas sourced from mélange diapirs in subduction zones

HR Marschall, JC Schumacher - Nature Geoscience, 2012‏ - nature.com
At subduction zones, crustal material enters the mantle. Some of this material, however, is
returned to the overriding plate through volcanic and plutonic activity. Magmas erupted …

YF Zheng - Geoscience Frontiers, 2019‏ - Elsevier
Crustal recycling at convergent plate boundaries is essential to mantle heterogeneity.
However, crustal signatures in the mantle source of basaltic rocks above subduction zones …

[HTML][HTML] Stagnant lids and mantle overturns: Implications for Archaean tectonics, magmagenesis, crustal growth, mantle evolution, and the start of plate tectonics

JH Bédard - Geoscience Frontiers, 2018‏ - Elsevier
The lower plate is the dominant agent in modern convergent margins characterized by
active subduction, as negatively buoyant oceanic lithosphere sinks into the asthenosphere …

Subduction factory: 4. Depth‐dependent flux of H2O from subducting slabs worldwide

PE Van Keken, BR Hacker… - … Research: Solid Earth, 2011‏ - Wiley Online Library
A recent global compilation of the thermal structure of subduction zones is used to predict

Water input into the Mariana subduction zone estimated from ocean-bottom seismic data

C Cai, DA Wiens, W Shen, M Eimer - Nature, 2018‏ - nature.com
The water cycle at subduction zones remains poorly understood, although subduction is the
only mechanism for water transport deep into Earth. Previous estimates of water flux,–exhibit …

High Sr/Y arc magmas and porphyry Cu±Mo±Au deposits: Just add water
