摘　　要：围山城金银成矿带呈北西—南东向狭长带状展布,在该带已发现有破山银矿、银洞坡金矿2个超大型银、金矿床,是我国重要的变质碎屑岩型银、金矿之一。除此而外,在该带相继发现规模不同的矿点、矿化点及物化探异常30余处,经多年实践和研究,把已知矿点、矿化点,与物化探异常结合起来,在对已知找矿信息综合研究和筛选、评序的基础上,最终确定银洞岭为重点找矿靶区,通过小范围找矿靶区定位分析和工程验证,终于取得找矿新进展。Weishancheng gold - silver mineralizing belt develops as a narrow NW - SE trending belt. Two super - large deposits, Pashon silver deposit and Yindongpo gold deposit, which are the important metaclastic deposits in China, have been found in the belt. Furthermore, more than 30 mineralising spots, geophysical and geochemical anomalies of different scales have been discovered in the belt successively. It is quite difficult to choose prospecting target through the prospecting information. After years practice and studies comhining known mineralization spots with geophysical and geochemical anomalies, the surrounding areas of Yindonglin silver deposit and Yindangpo gold deposit are chosen as chief prospecting targets on the basis of synthetical analysis, selection and evaluation of prospecting information. Development has been achieved through location analysis of small - scale prospecting target and engineering inspection.
