金龙山金矿带自东向西分为金龙山、腰俭、丘岭和鼓楼山4个呈似等间距分布的矿化富集段,矿(化)体主要赋存于上泥盆统南羊山组和下石炭统袁家沟组,研究表明地层可能仅是赋矿之所,而钙泥质粉砂岩、粉砂质页岩及钙质页岩等有利岩性对成矿起主要控制作用。区内构造极为发育,EW向区域性断裂控制整个矿带的展布,矿带内NE和近EW向次级断裂控制着矿带分段和矿(化)体的空间定位。因此,有利岩性组合和断裂联合控矿是金龙山金矿带的主要特征。
金龍山金礦帶自東嚮西分為金龍山、腰儉、丘嶺和鼓樓山4箇呈似等間距分佈的礦化富集段,礦(化)體主要賦存于上泥盆統南羊山組和下石炭統袁傢溝組,研究錶明地層可能僅是賦礦之所,而鈣泥質粉砂巖、粉砂質頁巖及鈣質頁巖等有利巖性對成礦起主要控製作用。區內構造極為髮育,EW嚮區域性斷裂控製整箇礦帶的展佈,礦帶內NE和近EW嚮次級斷裂控製著礦帶分段和礦(化)體的空間定位。因此,有利巖性組閤和斷裂聯閤控礦是金龍山金礦帶的主要特徵。

Jinlongshan gold ore belt,which is located in Southern Qinling,can be divided into four equi-distance mineralization segement of Jinlongshan,Yaojian,Qiuling and Guloushan from east to west.The orebodies of the gold belt are hosted in the Upper Devonian Nanyangshan Formation and the Lower Carboniferous Yuanjiagou Formation.Compared to the calcium muddy siltstone,silty shale,calcareous shale and other favorable lithology, the formations are just ore cluster place,but the lithology play an important role in ore-controlling.Furthermore, the structure is well developed in this area.The regional faults control the distribution of the entire ore belt,and the secondary faults strike in NE and EW control the distribution of the ore segment and the position of gold ore vein. Thus,the faults and favorable lithology together control the mineralization of Jinlongshan gold ore belt.
