%X Granodiorite dominated Mangqisu intrusions in the middle of Erben Mountains of South Tianshan was regarded as Devonian product previously. The authors dated the intrusions using zircon SHRIMP U-Pb approach, which yielded two ages of 296.9±5.4Ma and 304.2±11.6Ma. The intrusions also have characteristics of metaluminous and peraluminous syn-collision granite petrology. Coupled with the data of post orogenic k-rich granites in Permian and other regional geological data, the authors proposed the South Tianshan Paleozoic oceanic basin have been closed in Late Carboniferous.
