山东莱州三仓成矿带地质特征与构造岩相研究

三山岛—仓上成矿带位于山东省莱州市境内,其地质条件优越,成矿条件良好,是我国著名的金矿成矿带。本文主要介绍了该成矿带的地质特征与构造岩相特征,总结和分析了该矿带内矿床的矿物组合、结构构造、成矿阶段等;并对该成矿带的构造岩相带分布、地球化学元素组合、稳定同位素、蚀变带形成时代等进行了研究;在宏观上指出了有利成矿的区段和部位,确定了构造变形岩相带的成矿远景区,对该成矿带深部外围进行了成矿预测,并明确了下一步的找矿方向。

Research on geological characteristics and structural lithofacies of Sancang metallogenic belt in Laizhou,Shandong

Sanshandao-Cangshang metallogenic belt which is located in Laizhou city of Shandong province has superior geological conditions and good metallogenic conditions,and it is a famous metallogenic belt of gold in China.This paper mainly introduces the geological characteristics of the metallogenic belt and the characteristics of structural lithofacies,concludes and analyzes the mineral association,structures,metallogenic phases,etc.of deposits in the metallogenic belt,and researches the distribution of structural lithofacies,association of geochemical elements,stable isotope,formation age of alteration zone,etc.of the metallogenic belt.This paper macroscopically indicates the sections and positions good for metallogenesis,confirms the prospective metallogenic zone to form deformed lithofacies belt,perform metallogenic prediction to the deep and peripheral space of the metallogenic belt,and makes sure the direction of the next prospecting work.
