初论胶东福山北部地区斑岩成矿系统

摘要

福山北部地区位于胶东栖(霞)-蓬(莱)-福(山)成矿带北段.该区粉子山群大面积出露,褶皱断裂构造发育,中生代燕山晚期伟德山超单元幸福山单元和雨山超单元王家庄单元、水夼单元斑岩出露广泛,形成一套完整的斑岩多金属成矿系统.与该成矿系统有关的矿床成矿系列包括邢家山(钼钨)、王家庄(铜锌)、杜家崖(金银)和隆口(金铜)等矿床式.从现有研究成果看,该区具有较大找矿潜力,中-低温热液脉型、斑岩-矽卡岩型多金属矿应作为找矿主攻方向.%The north Fushan area locates in the northern part of Qixia-Penglai-Fushan metallogenic belt. There is a large area of Fenzishan group, developed folds and faults in the area. And it is characterized by extensive development of Mesozoic Xingfushan unit, Wangjiazhuang unit and Shuikuang unit porphyry. They form an integrated porphyry metallogenic system, which comprise the polymetallic series mineralization in Xingjiashan, Wangjiazhuang, Dujiaya and Longkou deposits. Based on the recent study, it is believed that there is great prospecting potential in the area.And middle-lower-temperature hydrothermal vein type and porphyry-scarn type gold and polymetallic deposits should be the main prospecting subjects in the area.
