摘　　要：通过对区域成矿地质背景的分析,结合区域矿产特征及地球化学异常特征,初步认为红卫山地区找矿前景良好,区内共圈定9处1∶20万地球化学岩石测量Ⅱ级异常和2处1∶20万水系沉积物测量异常,显示在本区内寻找以Sb、Pb、Zn、Au、Ag、Cu、Co、Sn、V为主的多金属矿产较有前景。矿体受石炭系或奥陶一志留系的碳酸盐岩、华力西期和印支期花岗岩类侵入岩以及纵向断裂构造三者的复合控制。成因类型属矽卡岩型。Based on the analysis of regional metallogenic geological background,combined with regional mineral characteristics and geochemical anomalies,9 sites of 1/200 000 rock geochemical anomaly measuring grade Ⅱ and 2 sites of 1 / 200 000 stream sediment survey anomalies were identified,indicating there are more prospects in looking for Sb,Pb,Zn,Au,Ag,Cu,Co,Sn,V-based multi-metal ores.The orebody belongs to genetic types of skern-type deposits,controlled by Carboniferous or Silurian Ordovician carbonate rocks,Variscan and Indosinian granite intrusions,as well as vertical faults in three of the composites.
