    Abstract
  • There is a set of mafic rocks developed along the Saergan strike-slip faults in the Keping area, which is of great significance to understanding the internal relations between the southwest Tianshan orogenic belt and the Tarim Craton. The zircon U-Pb geochronology and geochemical analysis of the Saergan Mafic rocks are used to investigate the effect of the Cenozoic intracontinental orogeny process of the Southwest Tianshan orogenic belt. The zircon LA-ICP-MS U-Pb age of the Saergan mafic rock is 49.14±0.8 Ma, indicating that the mafic rocks were formed in Eocene. Geochemistry data shows that the rocks have an important relationship with the remote effects of the collision between the Indian plate and the Eurasian plate.
