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。 A detailed study and reasonable explanation are given on the surface types and distribution rules of the polymetallic nodules and polymetallic nodules in the C-C deep sea polymetallic nodules in the eastern Pacific Ocean. It is considered that the morphological characteristics of the stratum are not only the result of the formation of the stratum The differences in microbial species also reflect the different hydrodynamic conditions and dissolved oxygen contents, which together determine the surface type of polymetallic nodules. The Antarctic underflow is the root cause of changes in the energy and environment, the redox potential, and the microbial species in subsea waters the reason. It provides a scientific basis for the distribution of polymetallic nodules and ore-forming prediction.
