Abstract

This paper provides information on the structure, chemical composition, and concentrations of microelements in ferromanganese crusts and siliceous crusts sampled on the Pervenets Rise, Sea of Japan. The crusts were formed by cementation of small fragments of green clays (celadonite) by manganese hydroxides (todorokite and birnessite) or by silica. The primary process involved the generation of celadonite, which was deposited as ore-bearing hydrothermal brine that was discharged in the caldera of the volcano or on its slopes. The crusts have a structure that indicates their formation during diffuse percolation of gas-charged hydrothermal brine along fissures or weakened zones in volcanic rocks and subsequent cementation of the resulting celadonite deposits with manganese or siliceous oxides. The manganese and the siliceous mineralization are separated over time, as well as, frequently, in space, and are more local.

日本海上Pervenets上升的热液层

摘要

本文提供了有关在日本海Pervenets Rise采样的锰铁结壳和硅质结壳中微量元素的结构，化学成分和浓度的信息。地壳是由氢氧化锰（菱锰矿和水钠锰矿）或二氧化硅胶结绿色粘土（硅藻土）的小碎片形成的。主要过程涉及生成青瓷，其以含矿热液形式沉积，并排入火山的火山口或其斜坡。地壳的结构表明，它们是在含气的热液盐水沿着火山岩中的裂缝或弱化区扩散渗滤以及随后用锰或硅质氧化物胶结所得的青瓷沉积物时形成的。
