【摘要】 硅质岩的研究面临着来源、成因及成岩、成矿作用等诸多方面的问题 ,绝大部分全岩分析结果都只能反映硅质岩地质地球化学行为的平均效果。硅质岩的组构信息研究有利于人们真正从时间、空间序列的角度去厘定硅质岩的形成、演化及其意义 ,而且这种以定向、微区、原位及深度分析为基础的研究思路对于其它类型岩石的微区研究亦有借鉴意义。更多还原

【Abstract】 In the research of the siliceous rock there are some problems involving the ori gin, genesis, diagensim and metallogenism that have not been worked out. The mos t of results of all rock analysis can only reveal the mean geological and geoche mical characteristics of the chert. By the results of fabric study, we can gain the accurate information about the formation, evolution and its significance of the siliceous rock. Also we can study accurately others kinds of rocks by means of micro-area, oriental, in situ and of depth analysis of the samples.更多还原
