Manifestations of authigenic mineralization along the continental slope of the sea of japan and in the tatar strait (materials of cruise 61 on r/v akademik oparin)

During the complex scientific research expedition in the Sea of Japan aboard the research vessel Akademik Oparin (Cruise 61), carbonate nodules were recovered by gravity coring, which were subsequently identified as pseudomorphs after ikaite (glendonite). The article presents the results of electron-probe and tomography studies of authigenic carbonates and gas-geochemical characteristics of host sediments occurring along the continental slope of the Sea of Japan and in the Tatar Strait.
