摘　　要：云南省凤庆县-云县地区位于云南西部,三江造山带南段,该区及周边金属矿床找矿效果较为显著。通过1∶5万水系沉积物的地球化学测量,对凤庆县-云县地区29种元素地球化学特征进行了初步分析,根据找矿远景区的划分原则,结合地质成矿规律,将研究区划分划分了3个找矿远景区,圈定出7个找矿靶区。初步认为铈、镧、钇、铷、铅、锌、铜、锡是区内的主要矿种,具有良好的找矿前景,为下一步找矿工作指明了方向。The area of Fengqing-Yun County,located in the western part of Yunnan Province,belongs to the southern part of Sanjiang orogenic belt.The prospecting effect of metal deposits in this area and its surrounding areas is remarkable.Through 1∶50000 geochemical survey of stream sediments in the area of Fengqing-Yun County,the geochemical characteristics of 29 elements are analyzed.According to the principle of division of prospecting areas,combined with geological metallogenic regularity,three prospective areas and seven prospecting target areas are delineated.It is preliminarily considered that there is good potential for the concentration and mineralization of elements of Ce,La,Y,Rb,Pb,Zn,Cu,and Sn,these elements are the main ore-forming elements in the study area,which shows directions for the next prospecting work.
