摘要
本文研究了南海中部铁锰结核(壳)的地球化学特征。南海铁锰结核(壳)以高Mn富Ni为特征。但不同沉积部位的铁锰结核(壳),化学成分也有一定的差异,这是受不同沉积区的物源特性,地化环境差异和沉积成矿过程中环境的变化所影响的结果。
Geochemical characteristics of Fe-Mn nodules (crusts) from the middle of the South China Sea have been studied. Fe-Mn nodules or crusts of the South China Sea are characterized by being rich in Mn and Ni. Chemical compositions of Fe-Mn nodules are different from those from different regions of sediments, which is controlled by polysources of sediments, environmental differences of deposition in different regions and environmental changes during the formation of Fe-Mn nodules and crusts.
