“…In summary, the mineral compositions and assemblages of both the Yanbian gabbroic and dioritic intrusions indicate their crystallization from water-saturated parental magmas, comparable with those mafic cumulates observed in modern subduction zones (Grove et al, 2002;Claeson and Meurer, 2004). The brief information of the four mafic intrusions is summarized in Table 1.…”

“…Late Paleozoic mafic intrusions in the area comprise gabbro and diorite, which are lithologically comparable with mafic cumulates in modern arcs (e.g., Grove et al, 2002;Claeson and Meurer, 2004). In this paper we report petrology, mineral chemistry (Appendix 1), zircon U-Pb ages, and whole-rock major, trace element and Sr-Nd-Hf isotopic compositions of four Permian subduction-related mafic intrusions from this area.…”

“…Thus the extrusive products of arc volcanism are often reworked as pyroclastic and volcaniclastic deposits into intra-arc and arc flanking basins of the adjoining forearc and back-arc. Water also influenced the crystallization of the plutonic sections of arcs producing amphibole-bearing gabbros and ultramafic rocks, as demonstrated experimentally by Müntener et al (2001) and geologically by Claeson & Meurer (2004) in the Proterozoic Trans-Scandinavian arc belt of Sweden.…”

Accretionary orogens form at intraoceanic and continental margin convergent plate boundaries. They include the supra-subduction zone forearc, magmatic arc and back-arc components. Accretionary orogens can be grouped into retreating and advancing types, based on their kinematic framework and resulting geological character. Retreating orogens (e.g. modern western Pacific) are undergoing long-term extension in response to the site of subduction of the lower plate retreating with respect to the overriding plate and are characterized by back-arc basins. Advancing orogens (e.g. Andes) develop in an environment in which the overriding plate is advancing towards the downgoing plate, resulting in the development of foreland fold and thrust belts and crustal thickening. Cratonization of accretionary orogens occurs during continuing plate convergence and requires transient coupling across the plate boundary with strain concentrated in zones of mechanical and thermal weakening such as the magmatic arc and back-arc region. Potential driving mechanisms for coupling include accretion of buoyant lithosphere (terrane accretion), flat-slab subduction, and rapid absolute upper plate motion overriding the downgoing plate. Accretionary orogens have been active throughout Earth history, extending back until at least 3.2 Ga, and potentially earlier, and provide an important constraint on the initiation of horizontal motion of lithospheric plates on Earth. They have been responsible for major growth of the continental lithosphere through the addition of juvenile magmatic products but are also major sites of consumption and reworking of continental crust through time, through sediment subduction and subduction erosion. It is probable that the rates of crustal growth and destruction are roughly equal, implying that net growth since the Archaean is effectively zero.Classic models of orogens involve a Wilson cycle of ocean opening and closing with orogenesis related to continent-continent collision. These imply that mountain building occurs at the end of a cycle of ocean opening and closing, and marks the termination of subduction, and that the mountain belt should occupy an internal location within an assembled continent (supercontinent). The modern Alpine -Himalayan chain exemplifies the features of this model, lying between the Eurasian and colliding African and Indian plates (Fig.

“…Therefore, all plutonic xenoliths from Martinique are samples from mid-upper crustal storage regions and high water contents play an important role in the petrogenesis of magmas. The high anorthite content in plagioclase, high wollastonite content in clinopyroxene, and amphibole compositions indicate crystallisation from a hydrous magma (Gaetani et al 1993;Sisson and Grove 1993a;Claeson and Meurer 2004). The presence of amphibole within Martinique plutonic xenoliths suggests that mid-upper crystal mushes can act as a sponge, storing and supplying the final erupted melts with water.…”
