铁锰结核成矿物质的直接来源是大洋底层水和沉积物孔隙水，结壳只有底层水，因此，底层水和孔隙水的物理化学特征就成为理解铁锰结核（壳）成矿作用特征与过程的关键。铁锰结核（壳）内部构造的两个明显特征是：①韵律性的环状纹层构造，和②树枝状构造，这两种构造是典型的远离平衡的非线性地质作用的产物。正常情况下，海底水—沉积物界面系统的底层水、孔隙水中Ｍｎ、Ｆｅ是不饱和的。因此，铁锰结核（壳）不可能在平衡状态下连续生长。本文提出铁锰结核（壳）生长的自反馈“振荡式”模型。
The direct source of iron-manganese nodule mineralization material is the pore water in the ocean bottom water and sediment, and the crust is only the bottom water. Therefore, the physicochemical characteristics of the bottom water and pore water have become the key factors for understanding the mineralization characteristics of iron-manganese nodules The key to the process. Two distinct features of the internal structure of the Fe-Mn nodules (shell) are: (1) rhythmic ring-like lamina structure and (2) dendritic structure, which are typical products of non-linear geologic effects far from equilibrium. Under normal circumstances, the bottom water of the seabed water-sediment interface system, pore water, Mn, Fe is not saturated. Therefore, Fe-Mn nodules (shells) can not grow continuously in equilibrium. This paper presents a self-feedback “oscillatory” model for the growth of ferromanganese nodules (shells).
