Abstract

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.
