The South Tianshan Terrane (STT) is located in the boundary between the south‐western Central Asian Orogenic Belt (CAOB) and the Tarim Craton and is a key area for understanding the geologic and tectonic history of the craton and the orogenic belt. In this paper, we report detrital zircon ages from the Late Palaeozoic and Mesozoic clastic sedimentary rocks from the southern part of STT. In combination...
The Bashisuogong (BSSG) complex is located in the tectonic transition zone between South Tianshan Collisional Belt (STCB) and Tarim Block (TB). The complex is composed of a mafic unit (mainly including gabbro and diabase) and a felsic unit (mainly composed of quartz syenite and alkali granite), both of which are crosscut by several diabase and alkali granite dykes. Here we present LA-ICP-MS zircon...
The Southern Tianshan Orogenic Belt (STOB) is an important region to understand the prolonged evolution of the Central Asian Orogenic Belt (CAOB). A comprehensive study of zircon U–Pb ages and Lu–Hf isotopes, whole-rock elements and Sr–Nd isotopes was carried out for two intermediate-mafic intrusions in the Baicheng and Heiyingshan areas of Southwest Tianshan. LA–ICP-MS zircon U–Pb dating yielded...
The Paleozoic and Early Mesozoic magmatic suites in the Central Asian Orogenic Belt (CAOB) provide important insights on the crustal growth and reworking process associated with the construction of the largest Phanerozoic orogen on the Earth. Among the tectonic blocks of the CAOB, the South Tianshan Terrane (STT) occupies the southwestern margin and is located adjacent to the Tarim Craton. Here we...
The South Tianshan Collisional Belt (STCB) and northern margin of the Tarim Block (NTB) are key areas for understanding the prolonged tectonic evolution of the Central Asian Orogenic Belt (CAOB). The Halajun region in Xinjiang province, NW China is located within the tectonic transition zone between STCB and Tarim Blocks. Several granitic intrusions and one mafic–ultramafic complex (Piqiang complex)...
