Description of Mn deposits and chemical composition of altered pelagic sediments of sites surveyed by R/V Vityaz in the Southern Basin of the Pacific Ocean

The object of the detailed investigations was an unusual material collected in the region of the Southern Basin of the Pacific Ocean floor, with features of intense manifestation of volcanic processes and subsequent hydrothermal alterations. These processes to a significant degree transformed the ferromanganese nodules and the pelagic sediments, causing the development of a new type of oceanic manganese mineralization.

本次详细研究所针对的对象为采集自太平洋洋底南部盆地区域的特殊地质物质，该区域具有强烈火山活动与后期热液蚀变作用的显著特征。上述地质作用在极大程度上改造了该区域的铁锰结核（ferromanganese nodules）与远洋沉积物（pelagic sediments），进而形成了一类新型海洋锰矿化（oceanic manganese mineralization）。
