摘　　要：枇库沟铅锌矿地处南秦岭山柞镇旬多金属成矿区南秦岭公馆-回龙镇汞、锑、金、银、铅、锌多金属成矿带上,产于中泥盆统杨岭沟组炭质灰岩与上泥盆统落家河组炭质千枚岩的接触带中靠灰岩一侧,两种岩性之间呈断层接触。通过对区域地质、矿体地质、矿床成因以及控矿因素等方面的分析、研究,提出了铅锌矿矿床成因为喷流-沉积型,根据喷流-沉积型铅锌矿成矿理论及成矿元素的分带性理论指导找矿,结合目前钻探揭露情况及钡元素的分布范围,确定了该区铅锌矿目前处于顶部相,为寻找深部矿体、潜力区块提供了理论指导。Pikugou Pb-Zn mine located in Gongguan-huilong town metallogenic belt of multi metallogenic in South Qinling, near the limestone of the contact zone between carbonaceous limestone of Yanglinggou Formation in Middle Devonian and carbonaceous phyllite of Luojiahe Formation in Upper Devonian, faul- ted contact between two kinds of lithology. Analysising regional geology, orebody geology, ore genesis and ore-controlling factors, proposed jet-sedimentary deposits of Pb-Zn mine. Guidance prospecting by jet- sedimentary deposits mineralization theory and zonation theory of ore-forming elements, determined Pik- ugou Pb-Zn mine situated in top phase according to the drilling situation and distribution of the Ba ele- ment, which provided theoretical guidance to find deep ore-body and potential area.
