Both lakes developed within the valleys of ancient rivers that once drained to the Pacific Ocean, being subsequently dammed by rising sills in the late Pleistocene/early Holocene. Seismic profiling and sedimentological analyses of cores from both lakes revealed similar successions consisting of marine to brackish sediments covered by lacustrine deposits. Radiocarbon dating indicates that the marine–lacustrine transition occurred at 8 ka and 8.15 ka, respectively. The correlation of this transition with global sea-level curves allowed the calculation of local uplift rates for the Holocene.Uplift rates for the lake basins amount to 0.42±0.71 and 0.49±0.44 mm/a, respectively, which are consistent with rates determined from a late Pleistocene marine terrace in the area. However, conspicuously higher, though likely transient, vertical movements at 8.83±2.7 mm/a and 11.36±1.77 mm/a, respectively, were calculated for the sills that block both lakes nowadays. These barriers are interpreted to be the surface expression of a blind reverse fault associated to the Morguilla fault system, a seismically-active structure that controls uplift and folding along the adjacent Arauco Peninsula.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Forearc uplift rates deduced from sediment cores of two coastal lakes in south-central Chile","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":"Forearc tectonics; Uplift rate; Lago Lanalhue; Lago Lleu Lleu; Arauco Peninsula; Sea-level change","OtherDescriptors":null,"Notes":null,"AnaPub":2010,"MonPub":null,"DateUpdate":"2014-10-23","DateCreate":"2011-10-24","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000286411500010","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.tecto.2009.05.006"},"refs":null,"anarec":{"AnaID":208926,"PubliDate":2010,"Pagination":"129-143","XtraPublOfAnaID":null,"ISBN":null,"Volume":"495","Issue":"1-2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44036,"SerRR":"Tectonophysics.
