对中国成矿体系的初步探讨

Preliminary study of Chinese mineralization system

文章通过对中国成矿体系的含义、特点、表达方式及演化过程的分析、界定,提出中国成矿体系是指中国境内各个地质历史时期所形成的矿床及其与成矿作用密切相关的地质要素所共同构成的整体。这一成矿体系是中国疆域在其漫长的演化过程中逐步形成的最终结果,具有明显的阶段性、多期叠加和成矿演化特征。应用矿床的成矿系列概念和方法初步构筑起中国成矿体系这一复杂体系的框架,有助于今后系统地研究其形成机制,并为成矿预测提供理论依据。这一体系大致可进一步分为太古宙的陆核成矿体系、元古宙的陆块边缘裂谷_裂陷槽为主的成矿体系、古生代的板块成矿体系及中_新生代的大陆成矿体系。

China has rich mineral resources. This paper deals with the systematical summarization of the metallogenic regularity with the purpose of serving the ore-prospecting work better. The Chinese Continental Mineralization System （CCMS） can be referred to as the whole group of mineral deposits located in the present continent of China and their genetically related geological factors. The Chinese Continental Mineralization System is the final result of mineralization through the whole evolutionary history of Chinese continental crust, obviously characterized by multiple stages of ore-forming evolution and overprinted by late stages of mineralization. Although the Chinese mineralization system is very complex, its framework can be outlined by the concept and methodology of the minerogenic series. The Chinese mineralization system can be divided into four sub-systems of mineralization, i. e., the Archean nucleus mineralization system, the Proterozoic land marginal rifting mineralization system, the Paleozoic plate tectonic mineralization system and the Mesozoic-Cenozoic continental mineralization system. The construction of the framework of the Chinese mineralization system contributes greatly to the further study of its formation mechanism and the ore prognostic work.
