摘要:

牟平—乳山金矿带位于胶东半岛东部,金成矿条件较好。荆山群、NNE向断裂及昆嵛山花岗岩岩体是金矿成矿的主要控制因素,含金矿体产于断裂破碎带中。在野外地质调查的基础上,结合遥感地质等资料进行构造解译,研究了牟乳金矿带的构造特征。通过对金矿带成矿地质背景、控矿断裂带的特征及形成机理、矿床的构造成因、牟乳金矿带的构造及成矿特征等进行分析和归纳,认为本区金矿床具有呈斜方网状排布、等距性和斜列性分布的规律。在此基础上,预测了金矿找矿靶区,筛选出7个有利成矿区,为下一步研究提供了有利的地质证据。

关键词: 构造特征, 成矿规律, 成矿预测, 牟乳地区

Abstract:

Muping-Rushan gold ore belt lays in eastern Jiaodong peninsula with a great metallogenic condition. Jingshan groups,NNE fault and intrusive bodies of Kunyu mountain are the main ore-controlling factors of gold ore mineralization,and the gold mine is distributed in the broken belts.The structural features of Muping-Rushan gold belt is researched by using remote sensing geological data on the foundation of field study.The geological background of metallogenic progress of gold belt,the features and the formation mechanism of ore-controlling fault,structural factor of deposit,the structural and metallogenic features are all analyzed and summarized,and the result suggests that the gold ore deposit in this area has a distribution rule of a rhombic mesh equidistant and oblique-arrangement property.And on this base,prospecting target area is predicted and seven favorable metallogenic area are filtered,which provides strong geological evidence for further research.

Key words: structural features, metallogenic regularity, metallogenic prognosis, Muping-Rushan area
