| 摘 要： | 本文主要研究太平洋ＣＣ区多金属结核ＣＣＡ３３，ＣＣＢ２９，ＣＣＣ５０，ＣＣＣ１４生长过程中锰、铁、镍、铜的通量（ＦＭｎ），ＦＦｅ，ＦＮｉ，ＦＣｕ）的变化规律．研究表明：１．结核生长过程中Ｍｎ，Ｆｅ，Ｎｉ和Ｃｕ的通量都是波动性的；２．ＦＭｎ与ＦＦｅ，ＦＮｉ，ＦＣｕ均呈正相关性；３．结核的元素通量与结核的成因类型和生长阶段密切相关，并记录了海底缺氧事件；４．结核的元素通量存在区域性差异，是沉积环境不同的反映。

| Abstract: | In this paper, the authors have studied regular patterns of variations of Mn,Fe,Ni,Cu fluxes during formation processes of polymetallic nodules CCA33, CCB29, CCC50,CCC14.1) Mn,Fe.Ni,Cu fluxes are wavy during the nodules formation processes.2) Mn fluxes (FMn) correlate positirely with FFe,FNi,FCu.3) The element fluxes of polymetallic nodules closely correlate with nodule forming mechanisms and growth stages, and record submarine anoxic events.4) The nodules in varied sites have different element fluxes, which reflects different sedimentary environments. |
