This review presents a summary of most current beliefs about the origins of granitic magmas, together with calculations of some important properties of granitic melts and magmas. Turning attention to magma ascent mechanisms, diapirism and dyking represent two competing end-member models. The differences in processes and products between the two are fundamental, and the implications of the differences are profound for the evolution of the continental crust. The weight of evidence favours dyke…

Granitic magmatism, from source to emplacement: a personal view
Abstract This personal view tracks the phenomenon of granitic magmatism from the source materials through partial melting, melt segregation, magma ascent and emplacement to the mechanisms by which
Igneous Rock Associations 7. Arc Magmatism I: Relationship Between Subduction and Magma Genesis
Dehydration of subducted oceanic lithosphere releases fluid into the overlying mantle wedge and initiates a chain of events culminating in the generation of magma that rises to form volcanic arcs.
Rates of tectonic and magmatic processes in the North Cascades continental magmatic arc
Continental magmatic arcs are among the most dynamic. geologic systems, and documentation of the magmatic, thermal, and tectonic evolution of arcs is essential for understanding the processes of

Geochemical and other evidence shows that granite magmas are generally derived from a mixture of melted crust and mantle material and the existence of a spectrum of types varying from largely
Perspectives on the source, segregation and transport of granitoid magmas
The pursuit of a comprehensive theory for the origin and evolution of granitoids is hindered by our incomplete understanding of the nature of the source and the mechanisms by which the magma is
Granitic magma transport by fracture propagation
Dike transport of granitoid magmas
Thermal and fluid-dynamical analyses suggest that for viscosities and density contrasts spanning the range considered typical for many calc-alkalic granitoids, dike ascent is a viable mechanism for
A new mechanism of granite emplacement: intrusion in active extensional shear zones
ONE of the principal ways in which continental crust grows is by the incorporation, from deeper within the Earth, of large volumes of granitic magma. A 'space problem' exists1 as to how these magmas
Dykes or diapirs
Until the last few years, diapirism reigned supreme among granitoid ascent mechanisms. Granitoid masses in a variety of material states, from pure melt through semi-molten crystal mushes to solid

Models for Granitoid Evolution and Source Compositions
This paper critically examines the bases of various models for the chemical evolution of granitoid suites. The proposed mineralogical, textural, and chemical criteria for the recognition of restite

In ascending through the lithosphere, andesitic magma probably cools by about 300 K. Since the ascent velocity and dynamics of ascent are unknown, several different phenomenological cooling models
