Authigenic carbonate and barite mineralization in sediments of the Deryugin Basin (Sea of Okhotsk).

Derkachev, A N; Bohrmann, Gerhard; Greinert, Jens; Mozherovsky, A V (PANGAEA, 2000-06-06)

Results of studies of mineralogy, geochemistry, and isotope parameters (d13C, d34S, d180, and 87Sr/86Sr) of carbonates and barites from sediments of the Deryugin Basin in the Sea of Okhotsk are presented. Diagenetic nature ...
Depth-related structure and ecological significance of cold-seep communities - A case study from the Sea of Okhotsk.

Sahling, Heiko; Galkin, Sergey V; Salyuk, Anatoly; Greinert, Jens; Foerstel, Hilmar; Piepenburg, Dieter; Suess, Erwin (PANGAEA, 2003-09-20)

We discovered and investigated several cold-seep sites in four depth zones of the Sea of Okhotsk off Northeast Sakhalin: outer shelf (160–250 m), upper slope (250–450 m), intermediate slope (450–800 m), and Derugin Basin ...
Massive barite deposits and carbonate mineralization in the Derugin Basin, Sea of Okhotsk: Precipitation process at cold vent sites.

Greinert, Jens; Bollwerk, S; Derkachev, A N; Bohrmann, Gerhard; Suess, Erwin (PANGAEA, 2002-09-07)

An area of massive barite precipitations was studied at a tectonic horst in 1500 m water depth in the Derugin Basin, Sea of Okhotsk. Seafloor observations and dredge samples showed irregular, block- to column-shaped barite ...
