The geochemical data of the Benzilan and Pantiange volcanic rocks from the Jinshajiang zone yielded characteristics similar to those of island-arc volcanic rocks:intensive enrichment in LILE and different depletion in HFSE,Nb,Ta,Ti,P and Zr,Hf.

• 金沙江带奔子栏二叠纪火山岩和维西攀天阁三叠纪火山岩的地球化学研究显示，它们具有类似于岛弧火山岩的地球化学特征，强烈富集大离子亲石(LIL)元素和相对亏损高场强(HFS)元素(明显亏损Nb、Ta、Ti、P，轻微亏损Zr、Hf)。
