Arc-basaltic melts of typical hydration state (≥ 2 wt% H 2 O) are buoyant relative to all
common crustal igneous rock types and may pass adiabatically from a mantle source …

As volatile and variably mobile components, halogens play key roles in magmatic,
metasomatic, mineralizing, and volcanic processes by influencing the physical and chemical …

Zircon composition has great potential as a pathfinder for porphyry Cu±Mo±Au systems. The
present study used a large integrated laser ablation-inductively coupled plasma-mass …

Abstract Porphyry Cu (±Mo±Au) and epithermal Au-Ag deposits are major sources of mined
metals and are commonly formed by magmatic-hydrothermal fluids derived from hydrous …

Increases in the magnitude of positive Ce anomalies in zircons from igneous rocks are often
interpreted to be controlled by progressive melt oxidation and have been used to provide …

Uranium-lead ages and trace element compositions of zircon from a series of shallow
porphyry intrusions document the temporal, chemical, and thermal magmatic evolution of …

Chlorine and sulfur are of paramount importance for supporting the transport and deposition
of ore metals at magmatic–hydrothermal systems such as the Coroccohuayco Fe–Cu–Au …

Geologic field relationships combined with spatially resolved geochemistry and high-
precision U-Pb geochronology of zircons allow quantification of magmatic processes …

Ciomadul is the youngest volcano in the Carpathian–Pannonian region produced crystal-
rich high-K dacites that contain abundant amphibole phenocrysts. The amphiboles in the …

Abstract The Late Triassic Guichon Creek batholith is a large (~ 1800 km 2), composite,
zoned batholith that hosts several large porphyry Cu-Mo deposits of the Highland Valley …
