| 英文摘要 | Mayile ophiolitic melange belt is one of the important Early Paleozoic ophiolite suites in the southern West Junggar, Xinjiang. It is controversial concerning the timing of opening and closure of the Mayile ancient oceanic basin. Based on detailed field investigations, Mayile ophiolitic melange emplaced in Middle-Upper Silurian Mayilashan Group flysch matrix or coexistenced closely with the Cambrian intrusive rocks in space. This indicates that Mayile ancient oceanic basin opened at least in the Cambrian. Observation along stratigraphic profiles suggest that there is angular unconformity between the Middle Devonian Kulumudi Formation and Mayilashan Group in lithologic characteristics, basic sequence, sedimentary environment. These reflect that early Late Paleozoic is a major transition period in the development of tectonic evolution of the West Junggar, and the deposition of continental sedimentary sequence in the lower part of Kulumudi Formation is a sedimentary response to the closure of Mayile Early Paleozoic ocean basin. Furthermore, this will provide important constraints on the tectonic evolution of the West Junggar orogenic belt and the tectonic framework of the Central Asian Orogenic Belt (CAOB) during the Paleozoic period. |
