栖霞西沟地区找金前景浅析

Primary Analysis on Gold Exploration Future in Xigou Area of Qixia City

栖霞市西沟地区金矿脉受NNE向断裂构造控制,矿化围岩主要是印支期文登超单元阜山单元中粗粒二长花岗岩,是典型的蚀变岩型金矿。该区处于NE向陡崖台前断裂成矿带西侧,NNE,NE向次一级断裂构造发育,矿化蚀变强烈,是有利的成矿地带,具有良好的找矿前景,是寻找大、中型金矿床的重要靶区。

Gold vein in Xigou area of Qixia city is controlled by fault structure with the trend of NNE, country rocks of mineralization are mainly composed of medium size monzonitic granite in Fushan unit of Wendeng superunit in Indo-China period. Geophysical abnormality and gold mineralization are very evident, which is a typical alteration type gold deposit. This area locates in west part of Douya—Taiqian fault belt with the trend of NE, secondary fault structure with the trend of NE, NNE developed well, and mineralization alteration is strong, which has good ore exploration future. Thus, it is an important target area for looking for large and medium type gold deposits.
