Abstract
The batholith exposed around Puerto Vallarta is part of the Guerrero tectonostratigraphic terrain, presumably accreted to Mexico during the Laramide orogenic phase. Fourteen sites on this batholith were studied palaeomagnetically and geochemically. Nine sites define a paleopole at 76.6°N, 181.8°E, with α95 = 6.6°, coinciding with the reference pole for stable North America. It is proposed that no important movements of the region relative to North America have occurred since emplacement of the intrusive rocks ∼ 80 Ma ago. This would mean that the Guerrero terrain was accreted to the Mexican continental margin before that time. Geochemical data support this interpretation, characterizing the rocks as volcanic-arc granites intruded at an active continental margin.

It is proposed that no important movements of the region relative to North America have occurred since emplacement of the intrusive rocks ∼ 80 Ma ago. This would mean that the Guerrero terrain was accreted to the Mexican continental margin before that time. Geochemical data support this interpretation, characterizing the rocks as volcanic-arc granites intruded at an active continental margin.</p></abstract></profileDesc><revisionDesc><change when="1988">Published</change></revisionDesc></teiHeader></istex:fulltextTEI><json:item><extension>txt</extension><original>false</original><mimetype>text/plain</mimetype><uri>https://api.istex.fr/document/9899F75710B08D255F0D1311B7D2FF8B3289C5EF/fulltext/txt</uri></json:item></fulltext><metadata><istex:metadataXml wicri:clean="Elsevier, elements deleted: tail"><istex:xmlDeclaration>version="1.0" encoding="utf-8"</istex:xmlDeclaration><istex:docType PUBLIC="-//ES//DTD journal article DTD version 4.5.2//EN//XML" URI="art452.dtd" name="istex:docType"></istex:docType><istex:document><converted-article version="4.5.2" docsubtype="fla"><item-info><jid>PEPI</jid><aid>88901252</aid><ce:pii>0031-9201(88)90125-2</ce:pii><ce:doi>10.1016/0031-9201(88)90125-2</ce:doi><ce:copyright type="unknown" year="1988"></ce:copyright></item-info><head><ce:title>Palaeomagnetism of the Puerto Vallarta intrusive complex and the accretion of the Guerrero terrain, Mexico</ce:title><ce:author-group><ce:author><ce:given-name>H.</ce:given-name><ce:surname>Böhnel</ce:surname><ce:cross-ref refid="FN1"><ce:sup>∗</ce:sup></ce:cross-ref></ce:author><ce:affiliation><ce:textfn>Institut für Geophysik, Westfälische Wilhelms Universität Münster, Corrensstr. 20a, D-4400 Münster F.R.G.</ce:textfn></ce:affiliation><ce:footnote id="FN1"><ce:label>∗</ce:label><ce:note-para>Present address: Laboratorio de Paleomagnetismo y Geofisica Nuclear, Instituto de Geofisica, Universidad Nacional Autonoma de Mexico, Ciudad Universitaria, 04510 Mexico D.F (Mexico).</ce:note-para></ce:footnote></ce:author-group><ce:author-group><ce:author><ce:given-name>J.F.W.</ce:given-name><ce:surname>Negendank</ce:surname></ce:author><ce:affiliation><ce:textfn>Abteilung Geologie, Universität Trier, Postfach 3825, D-5500 Trier F.R.G.</ce:textfn></ce:affiliation></ce:author-group><ce:date-received day="25" month="6" year="1987"></ce:date-received><ce:date-accepted day="19" month="10" year="1987"></ce:date-accepted><ce:abstract><ce:section-title>Abstract</ce:section-title><ce:abstract-sec><ce:simple-para>The batholith exposed around Puerto Vallarta is part of the Guerrero tectonostratigraphic terrain, presumably accreted to Mexico during the Laramide orogenic phase.
