文章通过对该地区已知地质资料的深入研究及详细的地质工作,共圈出金化探异常4个,钼化探异常带2条,其它多金属异常多条。认为近EW向构造(F4、F5)与NE向构造(F9、F13)交汇部位是今后找矿工作重点,寻找碎裂蚀变岩型隐伏金矿是今后找矿主要方向;钼矿找矿应以隐爆角砾岩型和斑岩型为主。

Geochemical anomalies of gold,silver,copper,lead and zinc in Shajingou area is closely related to the structure.The structure controls the mineralization of the gold deposit.Since 1980s,rock gold is the target mineral in this area which is searched for by several organizations,but no breakthrough is achieved so far.Through research on geological survey results from 2007 to 2010 and previous work in this area,this paper elaborates on the possibility of mineralization,ore controlling structure and prospecting direction of rock gold and polymetallic deposit in Shajingou area.Four blocks of rock gold geochemical anomalies,two Mo anomaly belts and many other polymetallic anomaly belts are found in the area.The author believes that:1) the intersection of approximate east-west structures (F4 ,F5 )and north-east structures (F9 ,F13 )is the focus of our future works;2)searching for cataclastic altered rock type hidden gold deposit is the main prospecting direction in the future;3)Mo deposits to be found are cryptoexplosive breccia type and porphyry type.
