В настоящей работе представлена группа грязевых вулканов, обнаруженных с помощью съемки многолучевым эхолотом на склоне подводной возвышенности Академический хребет между средней и северной котловинами озера Байкал. Анализ скелетов диатомей в грязевой брекчии выявил в массе вымерший вид Cyclotella iris et var., который ранее был обнаружен в керне скважины BDP-98. При помощи биостратиграфической и сейсмостратиграфической корреляции было установлено, что материал, входящий в грязевую брекчию исследуемых грязевых вулканов, имеет возрастной интервал от позднего миоцена до раннего плиоцена (от 5.6 до 4.6 млн лет) и мог быть поднят с глубины не более310 м ниже дна.</p><p> </p></abstract><trans-abstract xml:lang="en"><p>LakeBaikalis the only freshwater reservoir on Earth with gas-hydrate accumulations in its bottom sediments, partly due to the activity of mud volcanoes. This paper describes a group of mud volcanoes recently discovered on the slope of the Academician Ridge between the northern and central LakeBaikalbasins. Our analysis of diatom skeletons in the mud breccia sampled from the study area shows a high abundance of Cyclotella iris et var. These extinct species were also discovered in a core sample from BDP-98 borehole. Based on the biostratigraphic and seismostratigraphic correlations, the age of the mud breccia in the studied mud volcanoes ranges from the Late Miocene to the Early Pliocene (4.6 to 5.6 Ma). The correlations suggest that the material originated from a depth of less than310 m below the lake bottom.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>грязевой вулкан</kwd><kwd>грязевая брекчия</kwd><kwd>газовый гидрат</kwd><kwd>диатомовый анализ</kwd><kwd>биостратиграфия</kwd><kwd>сейсмостратиграфия</kwd><kwd>озеро Байкал</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mud volcano</kwd><kwd>mud volcanic breccia</kwd><kwd>gas hydrate</kwd><kwd>diatom analysis</kwd><kwd>biostratigraphy</kwd><kwd>seismic stratigraphy</kwd><kwd>Lake Baikal</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Baikal Drilling Project Group.
