Abstract

Carbonate nodules were recovered by gravity coring during a complex research expedition conducted in the Sea of Japan aboard the R/V Akademik Oparin (cruise 61), which were identified as pseudomorphs after ikaite (glendonite). This article presents the results of electron-probe analysis and tomography studies of authigenic carbonates and describes gas-geochemical features of host sediments along the continental slope of the Sea of Japan and in the Tatar Strait.

日本海大陆坡和鞑靼海峡自生矿化的表现（R/V Akademik Oparin 上的 61 号游轮）

摘要

在 R/V Akademik Oparin（61 号邮轮）在日本海进行的一次复杂研究考察中，通过重力取芯回收了碳酸盐结核，这些碳酸盐结核被鉴定为伊卡石（硅辉石）的假晶。本文介绍了自生碳酸盐的电子探针分析和断层扫描研究的结果，并描述了日本海大陆坡和鞑靼海峡沿岸沉积物的气体地球化学特征。
