中文摘要:

      在勘查区内通过1：10000土壤地球化学测量工作发现多处异常，结合区内成矿地质条件及矿种属性可将异常划分为3个异常区带，即西部HT1、东部HT2、南部HT3。经地表探槽工程揭露部分异常与已知矿体较为吻合，并且在勘查区东部HT2—3异常带内新发现4条蚀变岩型zn矿体。土壤地球化学测量在该区地质找矿中发挥了重要的指导作用，取得了良好的找矿效果。

英文摘要:

      A great deal of geochemical anomaly districts have been found by geochemical soil survey at scale of 1/10000 in exploration area,the geochemical anomaly district can be divided into three parts in combination with ore-forming geological conditions and mineral properties, which being western HT1, eastern HT2 and HT3 in the south. The surface trenching work revealed that some anomies match the known ore bodies better, and newly discovered four zinc ore body of altered rock type in HT2 -3 of the eastern part of exploration area. Geochemical soil survey plays important guiding role in geologic prospecting and shows that the methed of geochemical soil survey can yield favorable prospecting effect.
