Resumen de Relación entre composición de areniscas y procedencia. Casos de estudio en areniscas paleozoicas de la Zona Surportuguesa

María Carmen Moreno Garrido, Sonia Sierra del Pino

• Two different types of Upper Paleozoic sandstones from Southportuguese Zone are studied. Data coming from petrographic, sedimentological and regional analyses of the sandstones point to two different anomalies in relation with Dickinson and et al.�s provenance model. Discrimination between modal analysis and petrographic study of arenites is noted, as well as discrimination between source and tectonic setting of the provenance area.
