鲁西地区金矿床成矿规律浅析

A brief analysis of metallogenic regularity of gold deposits in Luxi area

鲁西地区与著名的胶东成矿带相隔,郯庐断裂带不仅与胶东地区金矿床具有密切的成因联系,也是鲁西地区含矿热液的重要运移通道,是区内重要的控岩导矿构造,与之相对应的次级断裂破碎带则是区内主要的赋矿构造。本文以归来庄、卓家庄、磨坊沟和东大湾金矿床为典型矿床,分析了各个矿床点的基本地质特征,进一步总结了鲁西地区金矿床的成矿规律,为区内进一步开展找矿勘查提供基础依据。

The Luxi area is separated from the famous Jiaodongmetallogenic belt, and the Tanlu fault zone is not only closely related to the Jiaodong area gold deposit, but also an important migration channel of ore-bearing hydrothermal fluid in luxi area, which is an important control rock ore structure in the region. The corresponding secondary fracture crushing zone is the main ore-bearing structure in the region. Taking returning Zhuang, ZhuoZhuang, Mill Ditch and Dongda Bay gold deposit as typical deposits, this paper analyzes the basic geological characteristics of each deposit point, further summarizes the metallogenic law of gold deposits in Luxi area, and provides the basis for further prospecting and exploration in the area.
