RESUMEN: La ZSP es la unidad geotectónica más al suroeste del Orógeno Varisco y se consideran los siguientes dominios: Pulo do Lobo
(Frasniense inferior y Fameniense superior), Faja Pirítica Ibérica (Givetiense-Viseense superior), Grupo Flysch Baixo Alen tejo (Viseense superior-Moscoviense superior) y Grupo Suroeste (Estruniense-Bashkiriense medio). En el proyecto GEO_FPI
se ha prestado especial atención a la Faja Pirítica Ibérica, ya que es una de las provincias metalogenéticas más importantes del
mundo, con depósitos de sulfuros masivos (VHMS) e importantes recursos de Cu, Zn, Pb, Ag, Au, Sn, In, Se, Ge.
Se ha realizado un trabajo de campo en común en la región fronteriza de España y Portugal para permitir una mejor inte gración y correlación de los datos geológicos y cartográficos. Además, se han seleccionado 31 afloramientos donde se han
recogido muestras para realizar un estudio de geocronología de U-Pb en circón. Los datos de edad obtenidos son importantes
para restringir las estructuras geológicas de la Faja Pirítica Ibérica que albergan la mineralización masiva de sulfuros y, por
otra parte, mejoran la visión geotectónica de toda la ZSP
ABSTRACT: The SPZ is the south westernmost geotectonic unit of the Variscan Orogeny and the following domains are considered: Pulo do Lobo (early Frasnian and late-Famennian), Iberian Pyrite Belt (Givetian-late Visean), Baixo Alentejo Flysch Group (late Visean-late Moscovian) and Southwest Group (late Strunian-mid Bashkirian). Special work was performed in the Iberian Pyrite Belt considered one of the most important metallogenetic massive sulfides deposit provinces (VHMS) with significant Cu, Zn, Pb, Ag, Au, Sn, In, Se, Ge, resources. A common fieldwork has been carried out in the Spanish/Portuguese border region to allow a better integration and corre lation of geological and mapping data. In addition, 31 outcrops have been selected where samples have been collected for a geochronology study of U-Pb in zircon. The age data obtained are important to restrict the geological structures of the Iberian Pyrite Belt that contain the massive sulphide mineralization. On the other hand, improve the geotectonic vision of the entire SPZ.
