| 摘 要： | 辽上金矿床位于胶东新发现的胶莱盆地东北缘成矿区之内,为胶东东部首例特大型金矿。矿区金成矿以充填作用为特征,载金矿物主要为自形—半自形结构黄铁矿和白云石,以网脉状、细脉状、微细脉状黄铁矿白云石细脉形式出现于岩石碎裂隙中,或以黄铁矿白云石大脉状充填于断裂构造中。矿石包括含金黄铁矿白云石脉型和含黄铁矿白云石脉蚀变岩型2大类。通过对比认为,该矿床为一新类型,即黄铁矿白云石脉型金矿床。这一新类型特大型金矿的发现,预示着胶莱盆地边缘地区具有较好的找矿前景,尤其在金牛山地区应有可能在短期内取得更大的找矿突破。

| Abstract: | Liaoshang gold deposit locates in the northeastern margin of Jiaolai basin. It is the first super large gold deposit discovered in eastern Jiaodong Peninsula. The gold mineralization here is characterized by filling activities, and main goldbearing minerals are idiomorphic hypidiomorphic pyrites and dolomites, which are always developed as net viens, veinlets and micro veinlets in the rock fissures, or as big veins filled in the fault structures. The ores are mainly categorized to goldbearing pyritedolomite veins and altered rocks bearing pyritedolomite veins. After comprehensive comparison and analysis, Liaoshang can be defined as a new type named pyritedolomite vein type gold deposit. The discovery endows the margin areas of the Jiaolai Basin with good prospecting potentiality. |
