Here the plate shallows slightly before plunging downwards, as a consequence of the rigidity of the plate. In order to constrain geochemical behavior of fluid-mobile elements hosted by serpentine phases during subduction processes, we carried out a geochemical study (trace elements and Pb isotopes) of a series of serpentinites and cumulates from the accretionary wedge of Greater Subduction accretionary complexes are composed of major and minor structural, stratigraphic, and tectonostratigraphic units. The renowned examples of mid-ocean ridges are the Mid- Atlantic Ridge and the East Pacific Rise. 2. Master complex concepts, enhance your academic performance, and excel in your studies.
