This paper describes a group of mud volcanoes recently discovered on the slope of the Academician Ridge between the northern and central Lake Baikal basins. 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\u201098 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 than 310 m below the lake bottom.\n\n[RUS]\n\u041e\u0437\u0435\u0440\u043e \u0411\u0430\u0439\u043a\u0430\u043b

Abstract

内容記述

Lake Baikal is 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 Lake Baikal basins. 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 than 310 m below the lake bottom.

[RUS]
Озеро Байкал является единственным пресноводным водоемом, в донных отложениях которого
обнаружены скопления газовых гидратов, часть из них связана с деятельностью грязевых улканов. 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 более 310 м ниже дна.
