山东省沂沭断裂带沂水段金矿特征及找矿方向研究

Study on Characteristics and Prospecting Direction of Gold Deposit in Middle Section of Yishu Fault Belt in Shandong Province

沂沭断裂带是中国东部著名的深大断裂,由4条NNE向主干断裂带和多条NNE向、NE向及NW向次级断裂组成的复杂活动断裂构造系统,自西向东依次为鄌郚—葛沟断裂、沂水—汤头断裂、安丘—莒县断裂、昌邑—大店断裂等四条主要断裂。近几年来,在该断裂上发现了龙泉站、牛家小河、南小尧、司家官庄、严家官庄、胡家官庄、刘家岭等金矿,使沂沭断裂带金矿找矿取得了突破。该文主要研究金矿成矿地质背景、矿床成因及矿床地质特征,进而为沂沭断裂带进一步开展金矿找矿工作提供了依据。

The Yishu Fault Zone is famous deep faults in the eastern Chinese complex, active fault system is composed of 4 NNE from the main fault zone and a plurality of NNE to NE to NW and secondary faults are composed of, from west to East were the four main faults Tang Gegou fault-a surname, Yishui Tangtou fault, Anqiu-Changyi-Juxian fault, Dadian fracture etc.. In recent years, Longquan station, niujiaxiaohe, Nan Xiao Yao, Si Jia Guanzhuang, Yan Jia Guan Zhuang, Hu Jia Guan Zhuang, Liu Jialing, the discovery of gold in the fracture, the Yishu Fault Zone gold prospecting breakthrough. This paper mainly studied the gold metallogenic geological background, ore genesis and geological characteristics of the deposit, and then provide the basis for further ore prospecting work in Yishu Fault zone.
