EGS XXV General Assembly, Nice, France, April 2000

SE24. Crustal melting and granite magmatism: causes and behaviours from pores to plutonic belts in orogens:

Event Information

The aim of this symposium is to bring together earth scientists with backgrounds in petrology, properties of minerals and rocks, and tectonics, to consider processes involved in, and the effects of, melt generation, segregation, ascent and emplacement during orogenesis. These processes and their effects are investigated using fieldwork, microscopy, geochemistry, experiments on crustal and analog materials, thermomechanical modeling using numerical methods, and theoretical investigations. Areas of current interest in the community include, but are not limited to: petrophysical properties of partially-molten rocks; the rheology of partially-molten crust; the mechanical effects of melt in the crust; mechanisms of segregation of melt in the crust; mechanisms of melt ascent; and, mechanisms of emplacement of magma in the upper crust. The conveners have identified four principal themes for this symposium, each of which will be introduced by a keynote speaker. These themes are: Physical Properties of Partially-Molten Rocks; Melt Flow Networks in the Crust; Mechanisms of Ascent and Emplacement of Magma; and, Geodynamic Significance of Melting During Orogenesis. The conveners welcome contributions using established or innovative techniques that address processes at any length scale and which give new insight into the generation of granite melt and its role during orogenesis.
