Many granites result from anatexis of common crustal rock types and the segregation,
aggregation, ascent and emplacement of the resultant magma. What then is the connection …

The nature of the interplay between tectonics and volcanism is a major question in
continental margin tectonics. The Southern Andes volcanic zone (SVZ), located at the …

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 …

Granitic magmas commonly ascend tens of kilometres from their source terranes to upper
crustal emplacement levels, or to the Earth's surface. Apart from its obvious bearing on the …

This review and personal account of basaltic volcanism concentrates on the geological
aspects and physical controls, unlike most others which concentrate on geochemistry. It …

The thermal structure of a generic subduction zone is investigated to elucidate the source
region of subduction zone volcanics. The steady state thermal field is evaluated for a model …

The end of an orogenic Wilson cycle corresponds to amalgamation of terranes into a
Pangaea and is marked by widespread magmatism dominated by granitoids. The post …

Significant volume of wet melting requires an influx of H2O-rich volatile phase. In hydrate-
breakdown melting, initial melt accumulation is diffusion-controlled and melt accumulates …

Field observations indicate that zones of inelastic deformation produced at the tips of
propagating dikes can be much larger than those produced at the tips of tensile cracks in …

Based on a case study in the Central Maine Belt of west-central Maine, USA, it is proposed
that crustal-scale shear zone systems provide an effective focussing mechanism for transfer …
