| 摘 要： | 对东太平洋C-C区深海多金属结核的叠层石包壳、多金属结核的表面类型及其分布规律进行了详细研究和合理解释,认为叠层石的形态学特征既是建造叠层石的微生物种类差异的表现,也是环境水动力条件和溶解氧含量不同的反映,这些因素共同决定了多金属结核的表面类型,而南极底流是造成海底水体能量环境、氧化还原电位和微生物种类变化的根本原因.为多金属结核的分布规律和成矿预测提供科学依据.

| Abstract: | The stromatolite coats, surface types and distribution rules of deep-sea manganese nodules are studied in detail and explained reasonably. It is suggested that microbes constructing stromatolite, water dynamic condition and oxygen content in water they decide the morphology characteristics of stromatolites and surface types of nodules. It is the Antarctic Bottom Water (AABW) that makes the change of energy environment of bottom water body and variety of microbes. The results provide scientific basis for manganese nodules distribution rule and metallogenic prognosis. |
