摘　　要：英坑钼多金属矿区位于粤东饶平县火山盆地外围,属武夷成矿带西南段莲花山矿集区。在总结矿床地质特征的基础上,从控矿地层、控矿构造、控矿岩体等方面分析了控矿因素,进而探讨了矿床成因。研究表明英坑矿区钼矿(化)体主要赋存于侏罗系南山村组凝灰岩地层中,受北西向断裂与其他方向断裂交汇控制,张性节理裂隙是导矿、容矿的最重要因素。矿床类型属斑岩型矿床外围与岩浆作用有关的高中温热液细脉裂隙充填型矿床,分析研究区控矿规律(矿体赋存规律),认为该区具有形成大型钨钼矿床的优越条件和良好的找矿前景,为该矿区后续找矿提供参考。Yingkeng molybdenum polymetallic deposit is located in the outer volcanic basin of Raoping county,eastern Guangdong,belonging to Lianhuashan ore concentration area in the southwest section of Wuyi metallogenic belt.Based on the summarizing of the geological characteristics of the deposit,the ore-controlling factors are analyzed from the ore-controlling strate,ore-controlling structure,ore-controlling rock mass and so on,and then the deposit genesis is discussed.The results show that the molybdenum deposit in Yingkeng mining area mainly exists in the tuff strata and its fracture zone of the jurassic Nanshancun formation,which is controlled by the intersection of NW and other direction faults.The tensile joint fissure is the most important factor for ore conduction and ore capacity.The deposit type belongs to the high and middle temperature hydrothermal thin vein fissure filling type deposit related to magmatism outside the porphyry deposit,the analysis of the district ore-controlling regularity coccurrence regularity of orebody indicate that this area has the superior condition and good prospecting prospect for the formation of large tungsten molybdenum deposit,which can provide reference for the follow-up prospecting of the mining area.
