Alkali-rich dykes of the Late Permian in Ulungur (乌伦古) area are representative products of granitic magmatism in the evolution of the Paleozoic orogenic belt in the East Junggar (准噶尔), North Xinjiang (新疆). We selected two representative samples for geochemical analysis (major and trace elements), and twenty-two zircon grains for zircon dating. Isoplot (ver3.0) was used to calculate isotopic age and...
Three types of granitoids were recognized in Tuerkubantao(土尔库班套) district, located on the northwestern margin of the Junggar Block. The zircon U-Pb age of the three types of granitoids suggests that they formed in different orogenic stage in response to the convergence and collision between Siberian and Kazakhstan plates. Biotite granite is similar to the volcanic arc granites in composition, with...
