LA-ICPMS zircon age of Tasite pluton in Sawuer region of west Junggar, Xinjiang


Fan, Y and Zhou, TF and Yuan, F and Tan, LG and Cooke, DR and Meffre, S and Yang, WP and He, LX, LA-ICPMS zircon age of Tasite pluton in Sawuer region of west Junggar, Xinjiang, Acta Petrologica Sinica, 23, (8) pp. 1901-1908. ISSN 1000-0569 (2007) [Refereed Article]


Sawuer region is located in west Junggar, Jimunai County of Altay district and Hefeng county of Tacheng district, Xinjiang province. The region is along the north margin of the Kazakstan-Junggar Plate. I- and A-type granites are widespread in Sawuer region. The Tasite pluton is an important multiple granitic intrusion which has close relationship with the Cu and Au mineralization. According to the LA-ICP MS age dating result of zircon, the crystallization age of Tasite intrusion is 337 ± 4Ma(1σ), corresponding to the early Carboniferous. The previous study on geological and geochemical characteristics has indicated that the Tasite pluton belongs to post-collisional granite. Therefore the west Junggar was in the post-collisional setting in early Carboniferous. The zircon U-Pb age of the Tasite pluton in this paper is one of the eldest ages of post-collisional granites in Junggar reported so far, providing a new evidence for confining the time framework of post-collisional period in Junggar.
