摘要
满洲里-克鲁伦成矿带于东北亚地区,是重要的多金属矿产资源集中区。通过对成矿带的地理位置和矿产资源的分布状况进行介绍,详细分析了成矿时代的3个主要阶段:新太古代-古元古代、晚古生代和中生代。其中中生代的成矿作用最为强烈。同时,通过探讨成矿带的地质构造特征,包括含矿建造特征、区域构造控矿作用、中生代火山构造以及岩浆侵入活动的控矿作用,总结了区域成矿模式,指出成矿带的金属成矿主要集中于中生代,并且成矿作用表现出多期次、多阶段性的特点。研究结果为理解该地区的成矿作用提供了新的视角,并对未来的地质找矿资源勘查工作提供了科学依据。
The Manzhouli-Kerulen Metallogenic Belt,situated in the Northeast Asian region,represents a significant concentration area for polymetallic mineral resources.This study introduces the geographical location and distribution of mineral resources within the belt and provides a detailed analysis of the three principal mineralization periods:Neoarchean to Paleoproterozoic,Late Paleozoic,and Mesozoic,with the most intense mineralization occurring during the Mesozoic.By examining the geological structural characteristics of the metallogenic belt,including regional structural controls on mineralization,characteristics of Mesozoic volcanic settings,and the influence of magmatic intrusions on mineralization,a regional mineralization model is delineated.It is highlighted that metal mineralization within the belt predominantly occurs during the Mesozoic and is characterized by polyphase and multistage processes.The findings of this research offer fresh insights into the region’s mineralization and provide a scientific foundation for future geological exploration and resource prospecting endeavors.
