摘要
磨山金矿床位于胶东三大金矿带中牟平-乳山金矿成矿带内,是一个中偏大型石英脉型金矿床,探获金资源量超过15t。金矿体受NNE向断裂控制,赋矿围岩为鹊山二长花岗岩,矿体主要呈脉状产出。矿石为黄铁绢英岩化花岗质碎裂岩夹石英脉,矿石矿物主要为黄铁矿、黄铜矿、方铅矿、闪锌矿,金矿物主要为自然金。根据矿床矿体地质特征及分布规律,预测4-1,3-1号矿体深部有较好的找矿前景。
Moshan gold deposit is located in Muping - Rushan metallogenic belt, which is one of the three major gold mineralization belts in Jiaodong area. Ore bodies occurred as veins and controlled by fractures and faults with the trend of NNE. Queshan rock are the host rock, and ore bodies occurred in vein type. Ores are fractured altered rock with quartz vein. The metalliferous minerals are mainly composed of pyrite, chalcopyrite, galena and sphalerite. Gold minerals are mainly native gold. Based on geological characteristics and the occurrence regularity, it is predicated that favorable prospecting potentiality can be expected in the deep of ④- 1 and ③- 1 ore body.
