长江源

通过K-Ar同位素年代学研究，将长江源区新生代的火山活动划分为3期：第Ⅰ期（40.1～35.1Ma）火山喷发较弱，形成小范围分布的细粒安粗岩和斑状粗面岩；

Based on K-Ar isotope chronological research , Cenozoic volcanism in the source region of the Yangtze River is divided into three phases . In the first phase ( 40.1-35.1 Ma ) volcanism was weak , forming fine-grained latite and porphyritic trachyte of limited distribution .
