The convergent margin and the magmatic arc have not remained static throughout their geologic histories, but instead have shown significant changes in position, geometry, and composition. For these reasons, the Trans-Mexican Volcanic Belt is the result of one of the most complex convergent margins on the planet, the subject of more than a century of scientific investigations, and at the core of the most notorious debates on Mexican geology.completedIgneous and metamorphic petrologyalkaline earth metalsbasementcalc-alkalic compositionchemical compositionCocos Platecompositioncontinental crustcontrolscrustDeep Sea Drilling ProjectDSDP Site 487extension tectonicsfaultsgenesisgeodynamicsigneous rocksIPODisotope ratiosisotopesLeg 66mafic compositionmagmatismmajor elementsmantlemantle wedgesmetalsMexican volcanic beltMexicoNd-144/Nd-143neodymiumneotectonicsoceanic crustplate convergenceplate tectonicsplatesrare earthssiliceous compositionspatial variationsSr-87/Sr-86stable isotopesstrontiumsubductiontectonicsthermal propertiesthicknessvariationsvolcanic rocksvolcanismurn:org.iodp:exp:66urnlargerWorkCitationcampaignurn:org.iodp:exp:66:site:487urnlargerWorkCitationstudyurn:org.iodp:exp:66urnlargerWorkCitationcampaignEnglishgeoscientificInformation-105.0000-94.000016.000022.0000Mexican volcanic belt
