摘　　要：吉林省桦甸市大楼金矿位于王家店岩体南侧,赋矿围岩为闪长岩、正长斑岩,产出受北东、东西向构造控制,目前已发现14条矿化带,主要的金属矿物为闪锌矿、方铅矿、黄铁矿;非金属矿物主要为石英。矿石结构多为自形粒状结构,块状、条带状构造。主要的矿石类型为含金黄铁矿石英脉型、含金黄铁矿-多金属石英脉型、含金黄铁矿-多金属蚀变破碎带型、含金黄铁矿蚀变岩型、含金黄铁矿-多金属蚀变岩型。成矿阶段可分为黄铁矿-石英阶段、含金硫化物-石英阶段、胶状石英-方解石阶段。The Dalou gold deposit in Huadian City, Jilin Province is located in the south of Wangjiadian rock mass. The host rocks are diorite and syenite porphyry, and its occurrence is controlled by NE and EW structures. At present, 14 mineralized zones have been found, the main metal minerals are sphalerite, galena and pyrite, and the non-metallic minerals are mainly quartz. The ore structure is mostly euhedral granular structure, massive and banded structure. The main ore types are gold-bearing pyrite quartz vein type, gold-bearing pyrite-polymetallic quartz vein type, gold-bearing pyrite-polymetallic altered fracture zone type, gold-bearing pyrite altered rock type and gold-bearing pyrite-polymetallic altered rock type. The metallogenic stages can be divided into pyrite-quartz stage, gold-bearing sulfide-quartz stage and colloidal quartz-calcite stage.
