摘要
通过不同景观区岩石测量方法技术研究 ,提出了以岩屑测量、构造岩石地球化学测量、脉岩地球化学测量和面型岩石地球化学为主体的岩石地球化学测量技术方法系统。在森林覆盖区和风成沙干扰区以及残山戈壁区等浅覆盖区域可采用岩屑测量圈定矿化地段 ;在岩石裸露区和已开采的矿山采用构造岩石裂隙测量和脉岩测量追踪深部盲矿 ;面型岩石测量以一定面积的网格采集单元组合样 ,其具有样品采集和分析数量少、获取信息量大。
Based on an investigation into the technologies and methods for rock survey in different landscape regions,this paper puts forward a technological and methodological system composed mainly of debris survey,structure rock geochemical survey, vein rock geochemical survey and planar rock geochemical survey.In such shallow cover regions as forest cover areas,eolian sand interference areas and relict mountain gobi areas,debris survey may be adopted to delineate mineralization sectors;in exposed rock areas and worked out mines, structure rock fissure survey and vein rock survey can be employed to trace deep blind orebodies.The planar rock survey is characterized by some merits like collecting and analysing relatively few samples,obtaining abundant information and delineating ore prospecting target areas of different scales.
