During the joint Russian-Vietnamese studies in East Vietnam Sea (known as Bien Dong or South China Sea), manifestations of new hydrocarbon-accumulating zones were discovered; evidences presence mineral indicators for solid minerals shelf deposits obtained; a unique zone, where accumulations ferromanganese crusts and nodules have been formed, was revealed first time; evidence properties deep-water fine-dispersed carbonate sediments (which makes it possible to attribute them an independent...

The bioindication of oil and gas fields is a field geomicrobiology that mainly devoted to the detection hydrocarbon-oxidizing microbial indicator species or functional genes in total DNA. However, it appears promising use physiological properties microorganisms deposit type hydrocarbons, particular their ability oxidize hydrocarbons under aerobic anaerobic conditions. In this study, most approach area was method used for assessing degradation hydrocarbons. When comparing molecular genetics...

В ноябре 2019 г. в Южно-Китайском море (исключительная экономическая зона СРВ) впервые за последние 30 лет была проведена крупная комплексная геолого-геофизическая совместная экспедиция ТОИ ДВО РАН и Вьетнамской академии наук технологий (88-й рейс НИС «Академик М.А. Лаврентьев»). Области изучения – геофизика, геология, гидроакустика, газогеохимия, гидрооптика, геомикробиология, палеогеография гидрология. толще вод донных отложениях обнаружены газогеохимические аномалии, сравнимые с...

This paper reports the results of third Russian–Vietnamese expedition (POI FEB RAS and Institute Marine Geology Geophysics, Vietnam Academy Science Technology) in Gulf Tonkin, South China Sea (April 2016) field work outcomes from 2016-2017. The studies revealed new specific features distribution origin gas-geochemical fields sediments within rift zone Red River along a 150-km profile. Four zones with high amplitude anomalies hydrocarbon gases, helium, hydrogen, carbon dioxide, monoxide were...

The peculiarities of the rare-earth elements distribution in surface bottom sediments Gulf Tonkin (South China Sea) are considered. According to results granulometric analysis, mainly represented by pelitic silt, silty pelite, and miktites. REE contents normalized chondrite composition show absence cerium anomaly, presence negative europium anomaly significant fractionation light heavy REE. values indicator ratios La /Yb ), Cr/Th, Th/Co, La/Sc, Th/Sc N indicate predominance rocks...

The review is devoted to the biodiversity of microorganisms capable degrading oil hydrocarbons in sea deep sediments and their relationship with accompanying microbiota, which includes sulfate-reducing denitrifying prokaryotes. Particular attention paid hydrocarbon-oxidizing bacteria, particular thermo- hyperthermophilic areas fields. Sulfate-reducing are widespread them. Some them not only sulfate reduction, but also hydrocarbon oxidation. Such were generally classified Deltaproteobacterium...
