豫西崤山地区具有优越的成矿地质背景，但长期以来仅发现了崤山金矿床等几个小型金矿床，规模远不及同一成矿带上的熊耳山和小秦岭地区，迫切需要实现找矿突破。通过分析寺家沟金矿区地质特征、地球化学异常特征，进而探讨其成矿潜力。矿区内圈出1∶2．5万次生晕异常5处，Ⅲ号异常内发现了 K1、K5等矿脉（体），资源量达中型金矿床和中型银矿床；Ⅳ号异常发现宽平4号脉，资源量达中型银矿床，Ⅴ、Ⅵ、Ⅶ号异常尚未得到验证。研究表明，Ⅵ号异常与Ⅲ号异常规模相当、Ⅶ号异常与Ⅳ号异常规模相当，均具中型矿床潜力；Ⅵ、Ⅶ号异常中发育北西向陡倾矿化断裂破碎带，与邻区已知矿脉相对应，矿化潜力大。综合分析认为，寺家沟金矿区具有达到大型金银矿床的潜力。

Xiaoshan region has excellent geological settings for mineralization,but for a long time only a few small gold deposits like Xiaoshan Gold Deposit have been found in this area,where the scale of deposits is far smaller than that in Xiong'ershanregion and Xiaoqinling region locating in the same metallogenic belt.This is a region eagerly loo-king for prospecting breakthroughs.By the research of characteristics of geochemical anomalies and geology in Sijiagou Gold District,the paper discussesthe mineralization potentials in the area.5 anomalies are delineated according to 1∶25 000 secondary halo.Vein K1 and K5 have been found within Anomaly III,the resources of which have respec-tively qualified them as middle scale of gold deposit and middle scale of silver deposit;Vein 4 of Kuanping Silver De-posit,a middle scale silver deposit,has been found within Anomaly Ⅳ;Anomaly Ⅴ,Anomaly Ⅵ,and Anomaly Ⅶhave not yet been verified.The research indicates an equivalent scale betweenAnomaly Ⅵ and Ⅳ,as well as be-tweenAnomaly Ⅶ and Ⅳ,all of which bear potentials for middle scale deposits.The NW-trending steeply inclined mineralized fracture zone exists in AnomalyⅥ and Ⅶ,and corresponding to the known veins of adjacent areas,has great potentials for mineralization.Comprehensive analysis shows that this region has the potential to make a large scale gold -silver deposit.
