Abstract
Large quantities of H2O are carried to great depth during subduction of sediment and hydrated oceanic crust. Much of this H2O is bound in hydrous minerals. When dehydration reactions proceed, the liberated fluid may migrate back up the slab or into the overlying mantle wedge (e.g. Peacock, 1990a, 1993a,b; Bebout, 1991a,b). Regardless of the fluid’s trajectory, the strong dependence of mineral solubility on pressure and temperature suggests that this flow may lead to extensive metasomatism. This is supported by field and analytical data, which show that metasomatic redistribution of elements is common in subduction-zone settings (Moore, Liou and King, 1981; Wyllie and Sekine, 1982; Tatsumi, Hamilton and Nesbitt, 1986; Sorenson and Barton, 1987; Sorenson, 1988; Bebout and Barton, 1989, 1993).
