【摘要】 运用地球化学块体理论,在青海西南部1∶20万区域化探数据基础上,进行了地球化学块体的圈定及内部结构的剖析。描述了地球化学块体的空间分布特征,分析了这些地球化学块体与地质体和已知矿床的空间对应关系;以及分析了各成矿元素的地球化学块体六级含量水平所对应的面积、可供资源量、浓集值等参数特征,选择几个重点的Pb、Zn的地球化学块体作了预测评价,并圈定出找矿远景区,为沱沱河地区找矿预测提供了重要依据。更多还原

【Abstract】 This paper applies the theory of geochemical blocks,based on 120k regional geochemical survey data in southwestern Qinghai province,marks the geochemical blocks and their inner structures,describes their spatial distribution,analyzes their corresponding relation to known deposits,studies the content levels,areas,resources and concentration of metallic elements in these geochemical blocks,and selects some key blocks to predict the potential of Pb and Zn mineralization with prospects determined,providing important clues to exploration in Tuotuohe area.更多还原
