Abstract

Abstract

The Early Mesozoic magmatism of the eastern Tianshan was just reported recently, the source and tectonic setting of which are poorly understood. Formed during the Early Mesozoic, the Bailingshanxi gabbro and porphyritic granite were recently discovered. In this study, new geochemistry, zircon U-Pb dating and whole-rock Sr-Nd isotope data are provided for these intrusions. Zircon LA-ICP-MS U-Pb dating results reveal that the gabbro and porphyritic granite emplaced at ca. 236 Ma and 228 Ma, respectively. The Bailingshanxi gabbro has low SiO₂ (43.50%-46.03%) content, and high CaO (11.40%-13.24%), Fe₂O₃^T(9.62%-11.84%) and MgO (6.02%-10.58%; Mg^#=53-69) contents. Meanwhile, it is characterized by high Ce/Pb, Ti/Zr, Ti/Y and Ba/Th ratios, and rich in LREE and LILE (e.g., Ba and Sr), indicating the Bailingshanxi gabbro was originated from the partial melting of the metasomated mantle wedge. Showing high SiO₂ (71.14%-72.71%), LREE ((La/Yb)_N=12.61-28.45) and LILE (e.g., Rb, K and Pb), the Bailingshanxi porphyritic granite was likely derived from the partial melting of the lower crust. Additionally, it has high Mg^# (39—-41) value and Ti/Y (154.40-306.18) ratios, implying mantle component played an important role in the formation of the porphyritic granite. Integrating with previous studies, the Eastern Tianshan is probably under inter-plat environment after 240 Ma, and the Bailignshanxi gabbro and porphyritic granite were formed during this stage.
