Granite magma formation, transport and emplacement in the Earth's crust

N Petford, AR Cruden, KJW McCaffrey, JL Vigneresse - Nature, 2000 - nature.com
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 …

Crustal melting and melt extraction, ascent and emplacement in orogens: mechanisms and consequences

M Brown - Journal of the Geological Society, 2007 - lyellcollection.org
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 …

Granite: From genesis to emplacement

M Brown - GSA bulletin, 2013 - pubs.geoscienceworld.org
At low temperatures (< 750 C at moderate to high crustal pressures), the production of
sufficient melt to reach the melt connectivity transition (∼ 7 vol%), enabling melt drainage …

Magmatic and structural controls on the development of porphyry Cu±Mo±Au deposits

RM Tosdal, JP Richards - 2001 - pubs.geoscienceworld.org
Abstract Porphyry Cu±Mo±Au deposits require the coincidence and positive interaction of a
series of individually commonplace geological processes. They, and all their genetically …

Multiscale magmatic cyclicity, duration of pluton construction, and the paradoxical relationship between tectonism and plutonism in continental arcs

M de Saint Blanquat, E Horsman, G Habert, S Morgan… - Tectonophysics, 2011 - Elsevier
The close relationship between crustal magmatism, an expression of heat dissipation, and
tectonics, an expression of stress dissipation, leads to the question of their mutual …

Granite ascent and emplacement during contractional deformation in convergent orogens

M Brown, GS Solar - Journal of Structural Geology, 1998 - Elsevier
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 …

On the emplacement of tabular granites

C ALEXANDER. R - Journal of the Geological Society, 1998 - pubs.geoscienceworld.org
Granites in both crystalline terranes and continental magmatic arcs tend to be circular to
elliptical in map view and vary in width from about 3 to 100 km. Available gravity and …

Time scales of pluton construction at differing crustal levels: Examples from the Mount Stuart and Tenpeak intrusions, North Cascades, Washington

JEP Matzel, SA Bowring… - Geological Society of …, 2006 - pubs.geoscienceworld.org
Deciphering the magmatic history of continental magmatic arcs, in general, and the growth
history of individual intrusions, in particular, is key to understanding the complex history of …

Depositional features and stratigraphic sections in granitic plutons: implications for the emplacement and crystallization of granitic magma

RA Wiebe, WJ Collins - Journal of Structural Geology, 1998 - Elsevier
Many granitic plutons contain sheet-like masses of dioritic to gabbroic rocks or swarms of
mafic to intermediate enclaves which represent the input of higher temperature, more mafic …
