Shear wave splitting measurements now allow us to examine deformation in the lithosphere
and upper asthenosphere with lateral resolution< 50 km. In an anisotropic medium, one …

The mechanism of magmatransportat depth influences direction magma moves, the distance
it travels before freezing, the degree to which it communicates chemically with the host rock …

Abstract Porphyry Cu-(Mo-Au) deposits are relatively rare but reproducible products of
subduction-related magmatism. No unique processes appear to be required for their …

The concept of strength envelopes, developed in the 1970s, allowed quantitative predictions
of the strength of the lithosphere based on experimentally determined constitutive equations …

The origin of granites was once a question solely for petrologists and geochemists. But in
recent years a consensus has emerged that recognizes the essential role of deformation in …

The volcanic history of the Long Valley region is examined within a framework of six
successive (spatially discrete) foci of silicic magmatism, each driven by locally concentrated …

Compositional data for> 400 pumice clasts, organized according to eruptive sequence,
crystal content, and texture, provide new perspectives on eruption and pre-eruptive …

The modification of magma through mixing or through assimilation of country rocks is
commonly inferred from various chemical and isotopic features of magmatic rock suites and …

The Earth's magmatism produces both volcanic and plutonic rocks. These two rock types
share many similarities, but also display significant differences that have led to a tendency to …

In orogenic belts, the common spatial and temporal association of granites with crustal-scale
shear-zone systems suggests melt transfer from source to upper crust was the result of a …
