栖霞-福山多金属成矿带地质特征及其成矿作用

Geological Characteristics and Mineralization of Qixia Fushan Polymetallic Metallogenic Belt

栖霞高家-香夼-福山邢家山一带矿产资源十分丰富,矿床(点)和矿种繁多,尤以多金属成矿作用最为突出,是胶东地区重要的金、铜、钼等多金属成矿区,有着十分良好的找矿前景。成矿带内矿床均分布于臧家庄盆地周缘断裂附近,大多赋存于中生代酸性侵入岩和粉子山群、蓬莱群变质地层中的碳酸盐岩接触带处,矿体受地层、构造及岩体三者联合控制。成矿作用受NE向断裂影响较大,除矽卡岩化外硅化、铅锌矿化、铜矿化、黄铁矿化、银矿化和钨钼矿化也较为发育。

Mineral resources are very rich in Gaojia in Qixia cityXiangku Xingjiashan in Fushan area with numerous deposits(spots)and mineral types,especially polymetallic mineralization.It is an important multimetallic metallogenic area of gold,copper and molybdenum in Jiaodong area.It has a very good prospecting prospect.The deposits in the metallogenic belt are located near the peripheral faults of Zangjiazhuang basin.Most of them are located at the contact zone of Mesozoic acid intrusive rocks and carbonate of Fanzishan group and Penglai group.The ore bodies are controlled by strata,tectonics and rock mass.Mineralization is greatly influenced by the faults with the trend of NE.In addition to skarnization,silicification,leadzinc mineralization,copper mineralization,pyritization,silver mineralization and tungstenmolybdenum mineralization are also well developed.
