自本世纪八十年代以来,随着古海洋学研究工作的进展,对深海洋盆地质环境的认识也产生了一个飞跃。随着对深海矿藏——多金属锰结核的综合调查,对锰结核生成的地质环境和生长速率也有了进一步的认识。在对深海洋底长柱状岩芯进行磁性地层、生物地层、气候地层等多学科的综合分析时,不仅发现了它们之间在地质历史时期存在着明显的相关性,而且在实践中证明,利用磁性地层进行地层对比,研究地质历史时期地质环境、沉积速率等也是行之有效的方法。通过对中太平洋海盆部分区域进 Since the eighties of this century, with the progress of paleoceanographic research, there has also been a leap forward in understanding the geological environment of the deep ocean basin. With the comprehensive investigation of deep-sea mineral deposits - polymetallic manganese nodules, there is a further understanding of the geological environment and growth rate of manganese nodules. In the multi-disciplinary comprehensive analysis of deep marine oceanic long columnar cores, such as magnetic stratum, bio-stratum and climate strata, it not only found that there is a clear correlation between them in geologic history, but also proved in practice Magnetic stratum stratigraphic comparison, geologic history geological environment, deposition rate is also an effective method.
