BACKGROUND For more than 100 years, the melt-dominated magma chamber has been
central to conceptual models of volcanism and igneous processes. Over the past few …

The emerging concept of a magma reservoir is one in which regions containing melt extend
from the source of magma generation to the surface. The reservoir may contain regions of …

Many workers accept a metamorphic model for orogenic gold ore formation, where a gold-
bearing aqueous-carbonic fluid is an inherent product of devolatilization across the …

The formation, storage and chemical differentiation of magma in the Earth's crust is of
fundamental importance in igneous geology and volcanology. Recent data are challenging …

Porphyry deposits are large, low-grade metal ore bodies that are formed from hydrothermal
fluids derived from an underlying magma reservoir. They are important as major sources of …

The lower plate is the dominant agent in modern convergent margins characterized by
active subduction, as negatively buoyant oceanic lithosphere sinks into the asthenosphere …

Granitoids are a major component of the continental crust. They play a pivotal role in its
evolution, either by adding new material (continental growth), or by reworking older …

Magma reservoirs play a key role in controlling numerous processes in planetary evolution,
including igneous differentiation and degassing, crustal construction, and volcanism. For …

Pressure is one of the key variables that controls magmatic phase equilibria. However,
estimating magma storage pressures from erupted products can be challenging. Various …

We present global and regional correlations between whole-rock values of Sr/Y and La/Yb
and crustal thickness for intermediate rocks from modern subduction-related magmatic arcs …
