The Late Carboniferous volcanic magmatic evolution in the Bogda Orogenic Belt is considerably important for understanding the evolution history of the Eastern Tianshan in the Central Asian Orogenic Belt. Our study focuses on the Upper Carboniferous Liushugou Formation in the Liudaogou and Qidaogou sections of Xishan Township in eastern Bogda. By analyzing the volcanics and sedimentary sequences, we present paleontological evidence, new zircon U–Pb ages, and geochemical data of the volcanics. The lithological composition of volcanics ranges from basic to acidic. The rhyolite has an age of 311.2 ± 1.7 Ma, which, when combined with guide fossils
