| 摘 要： | 石硐沟铅锌银矿床赋存于野牛滩花岗闪长岩侵入体外接触带中,矿床严格受石硐沟断裂带构造控制,矿化带长4 770m,矿体在矿化带中具分段赋存特征,而矿床中成矿元素具有从中温向中低温富集特征。通过对该矿床地质特征、物探及化探异常特征综合分析,认为该区域是寻找铅锌、钨钼矿,同时也是寻找金、银、铜、铁矿地区,具有较好的找矿前景。

| Abstract: | Shidonggou Pb-Zn-Ag deposit exists within the external contact zone of Yeniutan granodiorite intrusive, and is controlled by Shidonggou faulted structure. The ore bodies occurs section by section in the mineralized zone of 4 770m in length. The concentration of metallogenic elements appeared the evidence from low to high temperature. On the basis of geological features and the anomalies of geophysical and geochemical prospecting in this region, the author pointed out that it should be taken the relations of intrusive rock, faulted structure and gradient of metallogenic temperatures as carrying out regional prospecting and selecting the favorable place for prospecting. |
