中文摘要:
      通过开展凤庆鲁史—昌宁松山地区1∶5万水系沉积物测量工作,确定了Sn、Au、Sb、Hg、Ag为区内主要成矿元素。通过聚类分析和因子分析讨论了各元素在空间上的分布特征和组合关系。结合元素地球化学空间分布特征看,全区可明显划分为两个地球化学分区,各元素异常对断裂构造及成矿活动具有明显的反映。根据成矿地质条件和地球化学背景优选出了2个找矿预测区,其中博刀—上村—石灰窑—薅坝地A级找矿预测区为寻找金多金属矿的有利地区,找矿潜力大;浪坝寨—麻栗树—菖蒲塘—李子树C级找矿预测区为寻找电气石—石英脉型锡矿、石英脉型铅矿的有利地区,找矿前景一般。
英文摘要:
      Based on the 1∶50 000 steam sediment survey in Lushi, Fengqing- Songshan, Changning area, Sn、Au、Sb、Hg、Ag are determined as the main ore-forming elements in the area. Through cluster analysis and factor analysis, the spatial distribution characteristics and combinatorial relationships of each element are discussed. According to the spatial distribution characteristics of element, the whole area can be divided into two geochemical zones, each element anomaly has obvious reflection on fault structure and metallogenic activity. According to the metallogenic geological conditions and geochemical background, two prospecting areas were selected, Bodaoshan-Shangcun-Shihuiyao-Haobadi A grade prospecting area is a favorable area for prospecting for gold polymetallic ore and the prospecting potential is great; Langbazhai-Malishu-Changputang-Lizishu C grade prospecting area is a favorable area for prospecting for tourmaline-quartz vein type tin ore and quartz vein type lead ore and the prospecting prospect is general.
