The closure time of the Junggar Ocean is one of the hottest topics surrounding the tectonic evolution of the Central Asian Orogenic Belt (CAOB). This paper reports SIMS zircon U–Pb ages of the ophiolitic mélange and collisional igneous rocks in the Zhifang area, East Junggar. Our new results reveal the following evidence: (1) the West Hill ophiolitic mélange in the Zhifang area contains segments of...
The Taheir tectonic window is located at the southern part of the Yemaquan magmatic arc in East Junggar. This paper reports detailed petrology, mineral chemistry, whole rock and Sr–Nd isotope geochemistry, hornblende 40 Ar/ 39 Ar dating, in-situ zircon U–Pb dating and Hf isotope analyses from igneous and meta-igneous rocks from this region. Our new results show that the Taheir tectonic...
