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。
Based on geochemical block theory and 1: 200,000 regional geochemical data in the southwest of Qinghai, geochemical block delineation and internal structure analysis are carried out. The spatial distribution characteristics of geochemical blocks are described, the spatial correspondences between these geochemical blocks and geological bodies and known deposits are analyzed, and the area corresponding to the six levels of geochemical blocks of each ore-forming element is analyzed , Available for resources, concentration values and other parameters, select a few key Pb, Zn geochemical blocks for the prediction and evaluation, and delineated the prospecting prospect area, which provides an important prospecting for the Tuotuohe area in accordance with.
