Abstract

Abstract

Formation and evolution of the island/continental arcs are keys to understanding the plate tectonics and continent growth. In the Qilian and West Qinling, NW China, two different types of arc magmatic belts have been recognized. One is the North Qilian accretionary belt in the north, which consists of ophiolites, high-pressure metamorphic complex, and continental-type arc magmatic belt with ages of 520-440 Ma. The magmas are mainly intermediate to acid volcanics and intrusions. In the south is the Qi-Qin accretionary belt, which consists of Cambrian ophiolites (525-490 Ma) and Izu-Bonin-Mariana (IBM)-type intra-oceanic arc volcanic complexes (470-440 Ma). The Cambrian ophiolites are meanly composed of (1) the Hawaii-type picrite, (2) the within-plate alkaline basalt with intra-plate ocean-island-basalt (OIB) compositions, and (3) the within-plate tholeiitic basalt with enriched mid-ocean-ridge-basalt (E-MORB) compositions. The rock assemblage is best interpreted as an oceanic plateau of mantle plume within the Proto-Tethys ocean plate, obducted as ophiolitic fragments in the QQAB. The intraoceanic arc volcanic complexes are composed of high-Mg basalts, basaltic andesite, high-Al andesite, boninite and sanukite. Therefore, trench jam and subduction cessation caused by the arrival of an oceanic plateau are the primitive trigger for initiation of a new subduction zone with the development of younger volcanic sequence (~460-440 Ma).
