| 摘 要： | 冀北东坪金矿是赋存于水泉沟偏碱性杂岩体内的新类型金矿床，金矿化与硅化和肉红色钾长石化密切相关；矿物组合以自然－金碲化物－多金属硫化物－氧化物为主，并含有较多的次生自然金；矿脉受ＮＮＥ和ＮＷ向２组断裂构造控制。成矿物质来源于太古宇崇礼群变质岩和偏碱性杂岩体，成矿温度２７８～３８５℃，成矿时代为燕山期。矿床类型为重熔交代中高温石英脉蚀变岩型金矿床。

| Abstract: | Dongping gold deposit in northern Hebei is a new type one occuring in Shuiquangou subalkline complex. Gold mineralization has close relation with silicification and pale red Kfeldsparization. Mineral assembles are mainly natural goldgold telluridepolymetallic surfideoxide. The vein is controlled by NNE and NW trending fault structures. Oreforming materials originate from subalkline complex and metamorphic rock of Archaeozoic Chongli Group. The oreforming temperature is 278-385, the metallogenetic epoch is Yanshan period. The deposit is considered the moderatetohigh temperature, remelted and metasomatized quartz vein altered rocktype gold deposit. |
