A model for rates of disequilibrium melting during metamorphism,, and the textural relations between liquid and crystalline phases in partially molten aggregates. In contrast, the . of melting in the crust and mantle has received little or no attention. An evaluation of melting rates is important for a number of reasons, such as the following.

Formation and composition of H2O-undersaturated granitic melts,etals and some associated, less abundant, elements from lower to higher crustal levels. Granites have been the subject of numerous petrographic and experimental investigations. The first systematic experimental research was performed in the synthetic haplogranitic system Qz-Ab-Or-H.O (Tuttle & Bowen

Isotopic modification of the continental crust: implications for the use of isotope tracers in granthe Earth. This technique has been particularly important in studies of crustal magmatism, and has permitted the identification of granitoid source regions and the evaluation of magmatic mixing process (e. g.

,Fluid—rock interaction in the north-west Adirondack Mountains, New York State,ent in large volumes, will control a variety of metamorphic and metasomatic processes, including: the transport of chemical components and heat; the promotion or prevention of anatexis; and the genesis of economic deposits. The presence of fluids will also affect the rheology of the crust and its ge

Progressive reactions and melting in the Acadian metamorphic high of central Massachusetts and soutous rock types along the metamorphic field gradient in the metamorphic high of central Massachusetts and southwestern New Hampshire, USA. The progressive metamorphism of rocks of basaltic composition is discussed here more extensively than for rocks of common pelitic compositions, because detailed d

Granulite facies metamorphism of metabasic and intermediate rocks in the Highland Series of Sri Lanhe granulite facies Highland Series in the central part of the island, from which several authors separated a South West Group (e.g. Cooray 1965; Katz 1971, 1972); and the West and East Vijayan, both of which are predominantly composed of migmatitic granitic gneisses of middle to upper amphibolite f

Local, mid-crustal granulite facies metamorphism and melting: an example in the Mount Stafford area5 kbar) in a section of Proterozoic crust at .. 1820 Ma ago (Collins .. 1989b), and discusses processes responsible for unusually high temperatures at such shallow-crustal pressures. A relatively small area (about 260 km.) of low-pressure regional metamorphic rocks (mainly metapelites and metapsammi
