摘要
基于已有研究成果,本文对我国境内磁铁矿的成因进行了对比和归类,将其具体划分为4大类13小类,依据每种成因类型的磁铁矿在形态、结构、构造、形成环境、共生矿物、地球化学等方面的研究结果对11小类进行综述。同时,笔者建议未来对磁铁矿成因的研究中,在运用综合性方法的同时,也要注重探索研究区磁铁矿综合性成因,尽量减少只趋向于一种成因的认识,尤其是研究地质历史早期含矿地层。利用磁性矿物学和岩石磁学对磁铁矿成因的探索缺少,可进一步加强。
Based on the existing research results,the genesis of magnetite in China is compared and classified in this paper,which is divided into 4 categories and 13 sub categories.According to the research results of each genetic type of magnetite in the aspects of morphology,structure,structure,forming environment,symbiotic minerals and geochemistry,11 sub categories are summarized.At the same time,the author suggests that in the study of magnetite genesis in the future,while using the comprehensive method,we should also pay attention to the study of magnetite genesis in the study area,and try to reduce the understanding of only one kind of genesis,especially,in the study of ore-bearing strata in the early geological history.The exploration of magnetite genesis by magnetic mineralogy and petromagnetics is not enough,which can be further strengthened.
