藏南硅质岩显微形貌的对比研究

摘要

微组构信息对硅质岩的成因具有重要的指示意义，笔者以藏南四个剖面的硅质岩样品为研究对象，观察其各自的显微形貌特征，借此对其成因类型进行了研究分析。%Micro fabric information has an important indicating significance for the genesis of silicalite.Base on the research to the silicalite samples colleted from four different profiles in southern Tibet and the observ-ing to the respective microscopic morphological characteristics,the genesis types of silicalites have been clasified in the paper.
