摘　　要：龙头沟金矿位于南秦岭造山带东段山阳~风镇大断裂和镇安~板岩镇大断裂之间,为受构造控制的浅成中温热液矿床。金矿体赋矿主要为中泥盆统大枫沟组砂岩、板岩、砾岩地层中,受褶皱、地层及东西向主要断层平行的次一级的剪切断层和走向逆断层控制。矿石类型为构造蚀变岩型。作者根据矿区主要矿体地质特征,总结其控矿特征、成矿规律和找矿标志,提出了找矿方向,为下一步该类型金矿床找矿提供了依据。Longtougou gold deposit is located between Shanyang Fengzhen fault and Zhen’an banyanzhen fault in the eastern part of the South Qinling orogenic belt.It is a epithermal deposit controlled by structure.The gold bearing body is mainly composed of sandstone,slate and conglomerate in dafenggou formation of Middle Devonian,which are controlled by fold,stratum and secondary shear fault and strike reverse fault parallel to main faults in east-west direction.The ore type is structural altered rock type.According to the geological characteristics of the main ore bodies in the mining area,the author summarizes the ore control characteristics,metallogenic rules and ore prospecting indicators,and puts forward the prospecting direction,which provides the basis for the next exploration of this type of gold deposits.
