| 摘 要： | 本文以ＤＹ８５－４ 航次在东太平洋的调查为基础，概述了多金属结核在东西两海区的差异；分析了影响这种差异的因素；着重探讨了多金属结核的丰度、品位、覆盖率、Ｍｎ／Ｆｅ、与伴生沉积物、断裂带、火山、侵入岩的关系。发现造成两区结核差异的因素很多，但起主控作用的是断块、火山、岩浆、热液等活动所带来的物质及对海底物理化学环境的影响。

| Abstract: | Based on the investigational data obtained during the cruise DY85 4 made in the Eastern Pacific Ocean.This paper summarizes the disparities of polymetallic nodules in the eastern and western areas of the Pacific Ocean,analyzes the factors that cause this disparity with emphasis on the discussion on the relationship of the abundance,grade,rate of cover,Mn/Fe of the polymetallic nodules to the associated sediments,fault zones,volcanoes and irruptive rocks. Among the various factor that cause this disparity ,the primary controlling one has been found to be the materials that are produced by fault blocks,volcanic activity,magmatic and hydrothomal processes as well as their effects on the physical and chemical environments of the sea floor. |
