Abstract

The stratigraphic, sedimentologic and geometric reconstruction of the Tertiary volcano-sedimentary succession cropping out in the Mt Arcuentu-Funtanazza area (Central-Western Sardinia, Italy) has allowed us to recognize three phases of its sedimentary and volcanic evolution.The succession starts with continental conglomerates and lava flows, followed by a sequence of interbedded subaqueous sediments and distal pyroclastic flow deposits. Volcaniclastic breccias, mostly reworked, form the succession upper part.The Mt Arcuentu-Funtanazza area represents a transitional zone between volcanic sources and sedimentary basins, the latter being mainly carbonade (with sediment source probably in the west) during the second phase, and terrigenous (with a north-eastern sediment source) during the third
La reconstrucción estratigráfica, sedimentológica y geométrica de la sucesión volcán-sedimentaria terciaria aflorante en el área de Monte Arcuentu-Funtanazza (Cerdeña Centro-Occidental, Italia) nos ha permitido reconocer tres fases en su evolución sedimentaria y volcánica. En la base de la sucesión hay conglomerados continentales y flujos lávicos, seguidos por una secuencia de sedimentos subacuáticos y depósitos de flujo piroclástico distales. Las brechas volcaniclásticas, en su mayoría retrabajadas, constituyen la parte superior de la secuencia. El área de Monte Arcuentu-Funtanazza es una zona de transición entre edificios volcánicos y cuencas sedimentarias que son principalmente carbonátadas en la segunda fase y terrígenas en la tercera
