囊谦新生代钾质火山岩形成于碰撞后的板内构造环境,基性、中性和中酸性熔岩之间不存在分异和演化的关系,它们地球化学性质上的差异是源区部分熔融程度不同所致;钾质岩浆形成于50～80km深处的富集交代地馒;横断山地区一些拉分盆地中火山岩源区的部
The Neoproterozoic potassic volcanic rocks in the Baoqian Cenozoic were formed in the post-collision intraplate tectonic setting. There was no relationship between differentiation and evolution of the basic, neutral and intermediate-acid lavas. The difference in their geochemical properties was due to the partial melting degree Due to different reasons; Potassium magmatic magma was formed in the depth of 50 ~ 80km enrichment metasomatic mansions; some of the Hengduan Mountains pull the basin volcanic source of the Ministry
