本文收集了48组世界大洋各种沉积环境锰结核化学组成和生长速率数据并计算了它们的铁锰通量;讨论了不同环境的锰结核的铁锰含量之间的关系,以及锰通量与铁通量、Mn/Fe比的相关性;导出了由锰结核锰铁含量计算生长速率的经验关系;从本质上揭示了锰结核化学组成、生长速率与沉积环境的内在联系,为探讨锰结核形成机理提供了有力的依据.
【英文摘要】 48 data sets on the major chemical compositions (Mn and Fe concentrations) and growth rates of manganese nodules from different sedimentary environments of the oceans have been collected and their fluxes of manganese and iron have been calculated. It has been shown that although the chemical compositions and growth rates of manganese nodules from different areas of the oceans are largely different (Mn: 11.3-44.9%; Fe: 0.724-20.5%; growth rates: 0.80-200mm / 106yr) , there are small differences in Fe fluxes ..
