Abstract
The Papôa Volcanic Breccia (Peniche, West Portugal) is a Mesozoic pyroclastic deposit that includes numerous igneous and metamorphic xenoliths belonging to the Variscan basement of the Lusitanian Basin, in which this unit outcrops. These rocks correspond mostly to syenogranites and diatexites affected by intense pyrometamorphism and, despite their strong secondary alteration by weathering, they still preserve several original petrographic features that are traceable to the lithologies that comprise the Berlengas Archipelago, located 15 km offshore the Peniche coast. New geochemical and mineral chemistry data now indicate a genetic relationship between these basement xenoliths and the Late Devonian migmatites outcropping in the Farilhões Anatectic Complex. Such evidence strongly suggests the physical continuity of these high-grade metamorphic terrains at least to the Peniche region, thus constraining the nature and composition of the crustal block beneath the sedimentary sequences of the Lusitanian Basin in the studied location. In addition, in situ LA–ICP–MS U–Pb dating of rutile formed during the pyrometamorphic event endured by the xenoliths provided an age of 92.3 ± 1.4 Ma for the Papôa volcanic eruption, placing this occurrence within the third magmatic cycle related to the opening and spreading of the North Atlantic Ocean in the West Iberian Margin.
Resumen
La Brecha Volcánica de Papôa (Peniche, Oeste de Portugal) es un depósito piroclástico de edad mesozoica que se encuentra en la Cuenca Lusitánica y que presenta numerosos xenolitos ígneos y metamórficos procedentes del basamento Varisco de esa cuenca. Estas rocas corresponden en su mayoría a sienogranitos y diatexitas que están afectadas por un intenso pirometamorfismo y que, a pesar de su fuerte alteración secundaria debida a meteorización, conservan características petrográficas originales que permiten asimilarlas a las litologías que componen el Archipiélago de Berlengas, ubicado a 15 km de la costa de Peniche. Nuevos datos geoquímicos y de química mineral indican una relación genética entre estos xenolitos del basamento y las migmatitas del Devónico Superior que afloran en el Complejo Anatéctico de Farilhões. Estas evidencias sugieren la existencia de continuidad física de estos terrenos metamórficos de alto grado por lo menos hasta la región de Peniche, y definen la naturaleza y composición de la unidad cortical bajo las sucesiones sedimentarias de la Cuenca Lusitánica en el área estudiada. Además, las dataciones U-Pb mediante LA-ICP-MS in situ sobre rutilos formados en el evento pirometamórfico sufrido por los xenolitos, proporcionan una edad de 92,3 ± 1,4 Ma para la erupción volcánica de Papôa, ubicando este evento en el marco de tercer ciclo magmático relacionado con la apertura y expansión del Atlántico Norte en el Margen Occidental de Iberia.
