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 …

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

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 …

The magnetotelluric (MT) phase tensor is a property of the MT impedance that is resistant to
a common form of distortion due to unresolvable local structure. Review of the theory leads …

Abstract Long period (10–20,000 s) magnetotelluric (MT) data are being acquired across the
continental USA on a quasi-regular grid of∼ 70 km spacing as an electromagnetic …

Magnetotelluric (MT) data can image the electrical resistivity of the entire lithospheric column
and are therefore one of the most important data sources for understanding the structure …

An understanding of the formation of large magmatic reservoirs is a key issue for the
evaluation of possible strong volcanic eruptions in the future. We estimated the size and …

The textures of minerals in volcanic and plutonic rocks testify to a complexity of processes in
their formation that is at odds with simple geochemical models of igneous differentiation …

In a subduction zone, the volcanic arc marks the location where magma, generated via flux
melting in the mantle wedge, migrates through the crust and erupts. While the location of …

The transition to a low-carbon economy will increase demand for a wide range of metals,
notably copper, which is used extensively in power generation and in electric vehicles …
