摘要
Dangchuan, Located in the junction area of Qilian and North Qinling Orogenic Belts, has different granites occurring at different time. And these which are formed in Devonian are composed of Dangehuan intrusion and Huoyanshan intrusion. Based on the major and trace element, Sr-Nd isotope data, the authors suggest that the petrogenesis of the granites may be a result of continental uplift during the period of post-orogenic.
