摘要
谢家沟金矿位于焦家—新城断裂和招远—平度断裂之间,区内脉岩发育,主要类型有闪长玢岩、花岗闪长斑岩、闪长岩、石英闪长玢岩、辉石闪长岩、辉绿岩和煌斑岩等。按其与矿脉穿切关系划分为矿脉就位前脉岩、就位后脉岩,它们的地球化学特征表明这些脉岩具有良好的同源演化关系而且它们与成矿具有较为密切的时空关系。
The Xiejiagou gold mine is located between the Zhaoping fault zone and Jiaojia-Xincheng fault zone. Vein rocks are well developed in this gold ore field. The main rock types are dioridc porphyrite, diorite, quartz-dioritic porphyrite, gabbro, diabase and lamprophyres. The vein rocks can be divided into two types, one is that the ore veins are emplaced in the front of vein rocks, and the other in the rear. Geochemical characteristics of vein rocks show obvious affinity for them and the vein rocks have close relationship with gold mineralization in space and time.
