烟台福山北部地区金及多金属矿成矿系列

Metallogenic Series of Gold and Polymetallic Deposits in North Fushan Area of Yantai City

摘要:

烟台福山北部地区地处胶东栖（霞）蓬（莱）福（山）成矿带北段。该区粉子山群大面积出露，中生代岩浆活动强烈，褶皱断裂构造发育，形成一完整的热液成矿系统。对区内邢家山（钼钨）、王家庄（铜锌）、杜家崖（金）等典型矿床（式）研究发现：该区金属成矿作用与中生代燕山晚期斑岩关系密切，由高温至低温成矿作用在空间上展布规律明显，共同构成了与中生代燕山晚期中酸性岩浆侵入作用有关的金及多金属成矿系列。从现有研究成果看，中低温热液脉型、斑岩矽卡岩型以及浅成低温热液型金及多金属矿应作为该区找矿主攻方向。

Abstract:

The northern part of Fushan area is located in northern Qi (xia)Peng (lai) Fu (shan) metallogenic belt, which is one of the three most famous metallogenic belts in east Shandong peninsula. Fenzishan group well developed in this area. Mesozoic magmatism activity was very strong, and folds and faults developed well, which formed an integrated hydrothermal metallogenic system. According to the study on typical deposits, such as Xingjiashan deposit (molybdenum and tungsten), Wangjiazhuang deposit (cooper and zinc) and Dujiaya deposit (gold), it was found that metals mineralization had a close relationship with the porphyry in later Yanshan period of Mesozoic. These deposits were arranged regularly according to ore-forming temperature from higher to lower , and formed a metallogenic series of gold and polymetallic deposits. As shown by the recent research, it is suggested that middle-lower temperature hydrothermal vein type, porphyry type and epithermal type of gold and polymetallic deposits should be the prospecting subjects in the area.
