山东莱芜铁铜沟地区金矿成矿远景探讨

Study on Metallogenic Prospecting of Gold Deposit Tietonggou Area of Laiwu City in Shandong Province

通过对莱芜三岔河矿区先期的地质勘查工作,首先发现了赋存于闪长岩体内的金矿,对莱芜铁铜沟地区金矿成矿条件及地质特征有了新的认识,分析了断裂构造和中生代燕山晚期岩浆活动是区内导矿、控矿的主要地质因素,分析了区内物化探异常起因与闪长岩体内的金属硫化物关系密切,认为该区成矿远景较好。

According to previous geological exploration of Sanchagou mine area in Laiwu city,gold deposit occurred in the diorite has firstly been discovered.There is a new understanding of the gold ore forming conditions and geological characteristics of gold deposit in Tietonggou area of Laiwu city.It is regarded that fault structures and magmatic activities of late Yanshan period in Mesozoic are main geologic factors in ore transmitting and ore controlling.The geophysical and geochemical anomaly causes are close to metal sulfide in the diorite.It is proposed that there is a good metallogenic prospecting future in this area.
