论述了油房西银多金属矿床的矿体、火山原潜火山岩等地质特征，探讨了矿床成矿机理与成因，初步认为脉状银铅锌矿体受 NW向断裂构造和火山构造控制，层状铜钼矿体受隐伏花岗斑岩体制约，矿床属晚侏罗世末原早白垩世初形成的火山、潜火山-斑岩型系列组合矿床。
論述瞭油房西銀多金屬礦床的礦體、火山原潛火山巖等地質特徵，探討瞭礦床成礦機理與成因，初步認為脈狀銀鉛鋅礦體受 NW嚮斷裂構造和火山構造控製，層狀銅鉬礦體受隱伏花崗斑巖體製約，礦床屬晚侏囉世末原早白堊世初形成的火山、潛火山-斑巖型繫列組閤礦床。

The authors discussed the geologic characteristic of the ore body of Youfangxi Silver polymetallic deposit and volcanic -sub-volcanic,probed deposit's metallogenic mechanism and deposit genesis .And they preliminary thought that veined Cu-Pb-Zn Ore bodies are controled by NW-trending fractures structure and volcanic structure. the Stratiform copper molybdenum ore bodies is controled by Con-cealed granite porphyry rock mass.The deposit is belonged to volcanic ,subvolcanic-porphyry series deposit groups formed in the late episode of Late Jurassic-the Early episode of Early Cretaceous .
