摘要
广东大宝山矿田船肚矽卡岩型钨钼铜矿床受船肚花岗闪长岩体接触带的控制,按空间展布分为北矿带和南矿带。浅部钻探和坑道揭露显示:北矿带裂隙密集,由石英网脉型、构造破碎带型及少量矽卡岩型铜钼矿组成;南矿带为矽卡岩型钨钼矿。蚀变特征和矿化类型及成岩成矿年龄表明,该钼钨矿床是与燕山期花岗闪长岩浆活动有关的中高温热液充填交代矿床,成矿物质来源于花岗闪长岩。通过对有利的赋矿围岩分析、控矿构造解析和与大宝山矿区的控矿要素对比分析,认为船肚岩体是沿着寒武系(顶板)与泥盆系(底板)之间的推覆构造侵入的,靠近花岗闪长岩的内接触带是石英网脉型辉钼矿的有利找矿部位,而云英岩化则是有效的找矿标志。在深部和外围矽卡岩带是船肚矿区南、北矿带探寻矽卡岩型钼钨矿体最具潜力的部位。船肚北矿带次英安斑岩体内部、与斑岩体相连通的成矿前断裂带中和构造虚脱部位、块状和似层状矿体外围的断层、裂隙、节理连通部位及层间滑动虚脱部位都是下一步铜多金属矿找矿的有利部位。文章认为船肚矿区深部存在隐伏铜钼多金属矿体的潜力较大,是大宝山多金属矿田找矿突破的重点地段和重要接替资源区域。
        Chuandu skarn type tungsten, molybdenum and copper deposit in the Dabaoshan ore field, in Guangdong Province, is controlled strictly by the contact zone of Chuandu granodiorite intrusion and can be divided into thenorthern belt and the southern belt due to the space distribution. The data of shallow drillings and adits indicate that the northern belt is comprised of fracture concentrated quartz stockwork type, structure fracture zone type and few skarn type copper and molybdenum ore; the southern belt is comprised of skarn type tungsten and molybdenum ore.The mineralization type, alteration characteristics and ages of mineralization indicate that the origin of Chuandu MoW deposit is the high to intermediate temperature hydrothermal filling and replacing deposit related with Yanshanian granodiorite magmatic activity, and the ore material sources are from the granodiorite. By host rock studying, orecontrolling structure analyzing, and comparison between Chuandu and Dabaoshan deposits, this paper point out that the Chuandu granodiorite intruded following the thrust between the Cambrian hanging wall and the Devonian foot wall; The inner cotacting zone is favoerable prospecting space with greisenization as prospecting indicator. The skarn distribute in north and south ore belts are the most potential prospecting parts for skarn type Mo,W and Cu. The secondary porpyiritic dacite in north Chuandu ore belt, the fault zone connecting with the dacite, the structure collapse space, the faults, fractures, cleavages and collapse space between strata are favorable prospecting locations for Cupolymetallic mineralization. Therefore, it is potential on buried copper and molybdenum ore body in the deep of the Chuandu deposit, and Chuandu is proposed to be the potential area for breakthough on prospecting and the important resource supply for the Dabaoshan ore field.
