摘要
在华南大陆燕山期构造-岩浆作用及年代学理论研究的基础上,收集了大量该区的地质资料及前人研究成果,从成矿系列的划分、成矿岩浆岩的时代、岩浆活动与成矿、构造环境及动力学机制与成矿、矿产分布规律等方面系统阐述了近几年来该区在早燕山时期构造-岩浆作用与成矿研究的相关进展。发现在宏观区域上华南与中生代岩浆作用有关的矿床被划分为了新的五个成矿系列,而江西北武夷地区属第五系列,为武夷―云开成矿带中在印支-燕山期与混合花岗岩、花岗岩有关的成矿系列;随着测年技术及方法的提升,成矿岩浆岩时代的厘定也更加精准;早燕山期的主要矿化类型为岩浆热液型和斑岩型两种,其成矿物质可能起源于同一源区,并受到了构造环境边界及多期次动力学活动的制约;矿产分布规律已越发明确。
Based on the theoretical research on Yanshanian tectono-magmatism and geochronology of South China,the author gathered a large amount of geological data and previous research,and elaborated on the re-cent achievements in the study of early Yanshanian tectono-magmatism and mineralization in this area from the perspectives of division of metallogenic series,age of ore-forming magmatic rocks,magmatic activities and mineralization,structural environment and dynamic mechanics,as well as distribution regularities of mineralization and mineral resources.The author discovered that at the macro level deposits in South China related to Mesozoic magmatism were divided into five new metallogenic series,while Wuyi region of Jiangxi fell into the fifth series,namely the metallogenic series which was related to migmatitic granite and granite of Indo-Chinese-Yanshanian epoch in Wuyi-Yunkai metallogenic belt.With the improvements in dating technol-ogies and methods,the determination of age of metallogenic magmatic rocks became more accurate.The pri-mary mineralization types in early Yanshanian were magmatic hydrothermal type and porphyry type,both of which were possibly originated from the same source area and were restrained by structural boundary and multi-stage dynamic activities.The distribution regularity of mineral resources became more explicit.
