| 摘 要： | 依据多金属结核ＣＣＣ１４剖面上Ｍｎ、Ｆｅ、Ｎｉ、Ｃｕ的含量和有关的公式，本文计算该结核生长过程中瞬时生长速率和Ｍｎ、Ｆｅ、Ｎｉ、Ｃｕ的瞬时通量，并在结核中建立时间标尺，划分和对比结核生长阶段，重建结核ＣＣＣ１４８．７９３Ｍａ，Ｂ．Ｐ．以来的生长历史。研究结果表明，采用由铁、锰含量计算结核生长速率的公式，可详细了解结核生长过程，并能识别与提取强核中古海洋信息记录。

| Abstract: | Based on concentrations of Mn, Fe, Ni, Cu in the profile cutting the crust of polymetal lic nodule CCC14 from the Eastern Pacific Basin, the authors have calculated the instanta neous growth rates and instantaneous fluxes of Mn, Fe,Ni,Cu during the nodule formation process, constructed and highresolution timescale in the nodule crust, divided its growth stages and reconstructed the detailed growth history form 8. 793 Ma, B. P.. The studies suggest that by using formulas calculating nodule growth rates from Mn, Fe concentrations,a new way to understand the nodule growth processes and draw the paleoenvironmental information from the nodule crust records can be approached. |
