| Abstract: | The study area was located in Beishan metallogenic belt, Beishan region in Tianshan Mountain and Inner Mongolia and Beishan metallogenic belt was one of the important components for middle Asia type metallogenic belts. Based on the granodiorite rock mass as the research object, and through a comprehensive study of its petrology, zircon U-Pb dating and geochemical characteristics, the authors analyzed the genetic type, source and geological significance of granodiorite. |
