小秦岭钼金矿田位于华北克拉通南缘华山—熊耳山地块中西部，区内出露地层主要为结晶基底太古代太华群深变质片麻岩系，岩浆岩以燕山期经重熔或改造形成的花岗岩最为发育。秦南含钼金石英脉型矿床位于小秦岭金矿田北矿带秦南矿区。在野外地质工作的基础上，对秦南区内地层、含钼石英脉的产出、矿石结构构造、蚀变特征进行研究。分析认为秦南含钼石英脉是与秦岭造山带在245～211 Ma全面陆陆碰撞过程中的有关花岗斑岩侵位形成的斑岩型钼矿体，经后期酸性热液淋滤后，在断裂破碎带中进一步富集成矿。
小秦嶺鉬金礦田位于華北剋拉通南緣華山—熊耳山地塊中西部，區內齣露地層主要為結晶基底太古代太華群深變質片痳巖繫，巖漿巖以燕山期經重鎔或改造形成的花崗巖最為髮育。秦南含鉬金石英脈型礦床位于小秦嶺金礦田北礦帶秦南礦區。在野外地質工作的基礎上，對秦南區內地層、含鉬石英脈的產齣、礦石結構構造、蝕變特徵進行研究。分析認為秦南含鉬石英脈是與秦嶺造山帶在245～211 Ma全麵陸陸踫撞過程中的有關花崗斑巖侵位形成的斑巖型鉬礦體，經後期痠性熱液淋濾後，在斷裂破碎帶中進一步富集成礦。

Minor Qinling molybdenum-gold ore field is located in the southern margin of Huashan of North China Craton-Midwest Xiongershan block, exposure strata are mainly in mesometamorphic gneiss series of crystalline basement of Taihua Group.Granites in Yanshan period after remelting or transformation are most developed.Qinnan quartz vein type deposit containing molybdenum-gold is located in north mineralized belt of Minor Qinling Mountain gold field.Based on the field geological work,the output of the inland layer,the molybdenum quartz vein,the ore structure and the alteration charactersitcs are studied.Quartz vein containing molybdenum in Qinnan is porphyry type molybdenum ore body related to granite porphyry emplacement fromed in Qinling orogenic belt in 245~211 Ma full continent collisional process.
