Our new structural\u2013geochemical data reveal that it is actually an arc ophiolite comprising: (1) arc- or ophiolite-derived turbidites of two generations containing Late Ordovician\u2013Silurian and Late Devonian\u2013Early Carboniferous radiolarians; (2) a central intra-oceanic (Yixieke) arc with basalt\u2013andesite\u2013tuff\u2013agglomerate; (3) lower (Buziwan) oceanic crust containing dunite\u2013harzburgite\u2013gabbro. We propose the following tectonic evolution. South-dipping subduction in Late Cambrian to earliest Ordovician time generated the Yixieke arc on top of the Buziwan oceanic crust\u2013mantle. This subduction led to emplacement of the arc northwards onto the North Kunlun terrane (Tarim block), creating an active continental margin with northward subduction below it. The Kudi ophiolite was thrust southeastward over the incoming Kudi continental (gneiss) terrane in mid-Ordovician\u2013mid-Devonian time. During a tectonic hiatus in the Kudi region Late Devonian\u2013Carboniferous subduction further west led to development of the Oytag arc, formerly regarded as an equivalent of the Kudi ophiolite. Lower Permian arc lavas and Upper Triassic granites in the Xiananqiao arc south of Kudi mark the resumption of north-dipping subduction before final collision with the incoming Qiangtang block. Comparison with the Lapeiquan ophiolite in the Eastern Kunlun assists regional correlation along this Palaeozoic orogen and constrains Cenozoic displacement of the Altyn Tagh fault.<\/jats:p>","DOI":"10.1144\/0016-764901-093","type":"journal-article","created":{"date-parts":[[2008,5,21]],"date-time":"2008-05-21T21:10:59Z","timestamp":1211404259000},"page":"517-528","update-policy":"https:\/\/doi.org\/10.1144\/crossmark-policy","source":"Crossref","is-referenced-by-count":145,"title":["Arc-ophiolite obduction in the Western Kunlun Range (China): implications for the Palaeozoic evolution of central Asia"],"prefix":"10.1144","volume":"159","author":[{"given":"WENJIAO","family":"XIAO","sequence":"first","affiliation":[{"name":"1Key Laboratory of Lithosphere Tectonic Evolution, Institute of Geology and Geophysics, Chinese Academy of Sciences, PO Box 9825, Beijing 100029, P.R.
