The anomaly does not fit easily into any of the models that have been proposed: it may reflect the upwelling of an embryonic mantle plume or of a passive mantle domain responsible for or associated with a triple junction, possibly marking a recent shift into the area of the South American/North American plate boundary.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Mantle heterogeneity from trace elements: MAR triple junction near 14°N","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-27 01:31:04.439156","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1988,"MonPub":null,"DateUpdate":"2018-11-12","DateCreate":"2010-02-15","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1988N211000003","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/0012-821X(88)90043-X"},"refs":null,"anarec":{"AnaID":143701,"PubliDate":1988,"Pagination":"27-36","XtraPublOfAnaID":null,"ISBN":null,"Volume":"88","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42615,"SerRR":"Earth and Planetary Science Letters.
