| 英文摘要 | The Altun and West Kunlun Mountains, located on the southeast and southwest of the Tarim basin respectively, are two of the northernmost sutures of the Tethysides. The Early Paleozoic orogenic processes occurred there are important components of the Proto-Tethys history. After careful seismic interpretation, collision-related structures were revealed in the Tarim Basin. They indicate an Early Paleozoic collsion once occured on the southeastern margin of the Tarim Craton. That is the Tarim-Qaidam collision which resulted in the Altun Early Paleozoic collisional orogenic belt. The syn-collision structures in response to this collision include foreland fold-thrust belt (the Tangguzibas fold-thrust belt) and large basement-involved anticlines (the Lunnan, Tadong and Tazhong anticlines). They were formed in the Late Ordovician to Early Silurian. The post-collision structures are normal faults and theire combination of echelon transtensional fault zones. They were formed in the Middle Silurian to Middle Devonian. Deduced from the research results of the collision-related structures in the Tarim Basin and also the ophiolites and subduction-collison related magmatic and metamorphic rocks in the Altun Mountains, we can conclude that the oceanic crust of the ancient Altun Ocean, a branch of the Proto-Tethys, subducted under the Qaidam block since the Late Cambrian when is also the beginning time of the closing history of the oceanic basin. The acient Altun oceanic basin finaly closed at the end of the Middle Ordovician and resulted in the Tarim-Qaidam collision. This collision lasted to the end of the Early Silurian and then seased and evolved into the Middle Silurian-Middle Devonian post-collsion extension tectonic stage. So far, there is no collision-related structure indicates an Early Paleozoic collision on the Tarim' s southwestern margin. Therefore, in the Early Paleozoic, accretion-collision orogeny occurred in the Altun and accretionary orogeny in the West Kunlun. |
