摘　　要：惠东县伯公坳锡铜银多金属矿床位于紫金-博罗大断裂与莲花山断裂带西带的夹持区域,属于华南成矿省永安-梅州-惠州成矿带核心区域。区内共发现矿(化)体12条,整体走向北西—南东,呈团块状、条带状、浸染状充填于北西-南东向构造裂隙中。矿石类型主要为石英脉型,次为蚀变岩型,矿石矿物组合为黑钨矿、锡石、黄铜矿、辉铜矿、辉铋矿、深红银矿、辉钼矿、闪锌矿、方铅矿、铜蓝,从早到晚由自形-半自形晶结构向他形晶结构转变。在总结矿床地质特征的基础上,分析了控矿因素,认为矿床成因类型为与隐伏岩体有关的热液型矿床,工业类型为石英脉型和蚀变岩型。石英脉、变质砂岩、北西向断裂、化探元素异常和硅化蓝铜矿化等蚀变为重要找矿标志。The Bogongao tin copper silver polymetallic deposit in Huidong County is located in the clamp area between the Zijin Boluo Fault and the western belt of the Lianhuashan Fault,which belongs to the core area of the Yong'an Meizhou Huizhou metallogenic belt in South China's metallogenic province.A total of 12 ore(mineralized)bodies were discovered in the area,which were in the overall direction of NW-southeast and filled in the tectonic fracture of NW-southeast in the form of clumps,ribbons and disseminated.The ore type is mainly quartz vein type,followed by altered rock type.The mineral combination of the ore is wolframite,cassiterite,chalcopyrite,chalcocite,bismuth,crimson silver,molybdenite,sphalerite,galena,covellite.transitioning from euhedral-subhedral to anhedral crystal texture from early to late stage.On the basis of summarizing the geological characteristics of the deposit,the ore-controlling factors are analyzed.It is considered that the genetic type of the deposit is a hydrothermal deposit related to hidden rock mass,and the industrial type is quartz vein type and altered rock type.
