山东文登鞠格庄金矿成矿特征及找矿方向

Metallogenesis Characteristics and Ore Prospecting Direction of Jugezhuang Gold Deposit in Wendeng of Shandong Province

摘要:

文登鞠格庄金矿体位于山东省牟平乳山金成矿带外围，米山断裂东侧，是一个石英脉型金矿体。金矿体受EW向断裂构造控制，围岩为新元古代荣成序列邱家单元片麻状细粒二长花岗岩。矿石为黄铁矿化石英脉、黄铁矿化硅化绢云母化花岗质蚀变岩，矿石矿物主要为黄铁矿、方铅矿、黄铜矿、褐铁矿，金矿物主要为自然金。根据矿体地质特征和分布规律，预测①号金矿体深部、走向方向以及周围米山次级断裂构造内有较好的找矿前景。

Abstract:

Jugezhuang ore body located in the surrounding area of Muping Rushan gold mineralization belt, and east of Mishan mountain. It is quartz vein type gold deposit. Gold ore bodies are controled by faults with the trend of NW. Its orebearing country rocks are gneissic fine adamellite of Qiujia unit in Neoproterozoic Rongcheng superunit. Ore bodies output as plateshaped quartz vein. Ores are pyritized quartz vein, pyritized, silicified, sericitization granitic altered rock. Ore minerals are pyrite, galena, chalcopyrite and limonite. Gold minerals are native gold. According to geological characteristics and distribution of ore bodies, it is predicted that there is good prospecting future in the deep part, trend direction and surrounding area of No.① ore body.
