The seeps at the lake floor are identified as methane seeps and occur in an area of high heat flow, where the base of the gas-hydrate layer shallows rapidly toward the vent sites from  400 m to  150 m below the lake floor. At the site of the seep, a vertical fluid conduit disrupts the sedimentary stratification from the base of the hydrate layer to the lake floor. The seeps are interpreted to result from local destabilization of gas-hydrate caused by a pulse of hydrothermal fluid flow along an active fault segment. This is the first time that methane seeps and/or mud volcanoes associated with gas-hydrate destabilization have been observed in a sublacustrine setting. The finding demonstrates the potential of tectonically controlled gas-hydrate destabilization to cause extreme pore-fluid overpressure and short-lived mud volcanism.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Sublacustrine mud volcanoes and methane seeps caused by dissociation of gas hydrates in Lake Baikal","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"gas hydrates; hydrothermal vents; Lake Baikal; methane; mud volcanoes; seepage","OtherDescriptors":null,"Notes":null,"AnaPub":2002,"MonPub":null,"DateUpdate":"2014-10-09","DateCreate":"2011-11-03","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000176607500013","VABBcode":null,"OpenAcc":0,"DOI":"10.1130/0091-7613(2002)030<0631:SMVAMS>2.0.CO;2"},"refs":null,"anarec":{"AnaID":209215,"PubliDate":2002,"Pagination":"631-634","XtraPublOfAnaID":null,"ISBN":null,"Volume":"30","Issue":"7","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42917,"SerRR":"Geology.
