| 摘 要： | 海阳小纪金矿赋存于早白垩世莱阳群水南组中。矿体多为扁豆体状，矿石矿物成分简单，金矿物以自然金为主，其他金属矿物以赤铁矿、黄铜矿为主。通过分析成矿控制条件认为：莱阳群分布区是寻找该类型金矿的地层标志；NE-NNE向断裂带中，硅化、黄铁矿化、黄铜矿化等蚀变特征是寻找金矿(化)体的围岩蚀变标志；中生代岩体及燕山晚期脉岩发育是寻找该类金矿的岩浆岩标志。其矿床成因属多源多期低温热液充填型金矿床。 |

| Abstract: | Xiaoji gold deposit in Haiyang city occurrs in Shuinan formation of early Cretaceous Laiyang group. Orebodies are mainly lenticulated type with simple composition. Natural gold minerals are mainly gold ores, while other minerals are mainly composed of hematite and chalcopyrite. Through analysis on ore-controlling condition, it is regarded that Laiyang group distribution area is strata mark for looking for this kind of gold deposit, alteration characteristics as silicification, pyritization and chalcopyritiz... |
