Granitic magmas extracted from crustal sources can form over a wide variety of P, T and aH 2 O conditions. Both fluid-present and effectively fluid-absent conditions can yield granitic …
Granitoids are a major component of the continental crust. They play a pivotal role in its evolution, either by adding new material (continental growth), or by reworking older …
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 …
Migmatites are highly heterogeneous rocks found in high-grade metamorphic environments; they are commonly encountered in the continental crust. Until now, many geologists have …
EW Sawyer - Journal of metamorphic Geology, 2001 - Wiley Online Library
The grain‐and outcrop‐scale distribution of melt has been mapped in anatectic rocks from regional and contact metamorphic environments and used to infer melt movement paths. At …
Pseudomorphs of melt-filled pores, recognized by their generally cuspate shape, are used as diagnostic for the former presence of partial melt. They are commonly observed in …
JD Clemens - Granulites and crustal evolution, 1990 - Springer
Granulites may be produced in either fluid-present or fluid-absent metamorphism. Fluid- present granulites can be formed by relatively low-T dehydration reactions, in the presence …
Partial melting is the fundamental process by which juvenile crust was produced from the mantle and subsequently reworked to become the stable, compositionally-differentiated …
With less than two decades of activity, research on melt inclusions (MI) in crystals from rocks that have undergone crustal anatexis–migmatites and granulites–is a recent addition to …
