摘　　要：本文利用扫描电镜及能谱分析技术,对产自太平洋中、北部12个站位,不同类型的铁锰结核进行了详细的显微结构及其微区化学分析。结果表明,不同Mn/Fe结核的显微结结构和元素含量不同;在高Mn/Fe结核中发现有微体生物化石和铁锰细菌存在。作者提出,利用扫描电镜及能谱分析技术,可以对研究大洋铁锰结核的地球化学特征及其成因提供极其重要的信息。The microstructure and composition of the different types of ferromanganese nodules in 12 stations from the Northern Central of Pacific were studied by EDAX. The results shown that: (1) The microstructure and composition of the different types were different with the difference of Mn/Fe in the ferrmanganese nodules; (2) It have been found that there are microbiological fossil and bacteria in the ferromanganese nodues. They may be used .therefore,as providing imporfant information for study geo-chemical characteristics and formation mechanism of ferromanganese nodules from the pacific.
