On many profiles, the reflective layer is associated with regions of extension, suggesting that the reflectors originate by some form of ductile flow or magmatic intrusion during rifting. To test this hypothesis, we have examined geophysical and geological data from the Valencia Trough, a rift basin of Late Oligocene/Early Miocene age. From a comparison of profiles in different parts of the trough, and independent constraints on the initial crustal thickness, we argue that the reflective layer in this basin was probably already in the crust before rifting, and that a mid-Tertiary extensional event is not required to explain it.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Evidence for reflectors in the lower continental crust before rifting in the Valencia Trough","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":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1990,"MonPub":null,"DateUpdate":"2005-11-24","DateCreate":"2005-11-24","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1990EM76000059","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":77914,"PubliDate":1990,"Pagination":"631-635","XtraPublOfAnaID":null,"ISBN":null,"Volume":"348","Issue":"6302","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43431,"SerRR":"Nature: International Weekly Journal of Science.
