Interpretación sedimentológica y paleogeográfica del nivel de areniscas eocénicas de Sarrià de Ter (Prov. de Gerona)

There is in this work a description of sedimentological characters of the medium Eocene sandstone level from Sarriá de Ter (Gerona province Spain) and an interpretation of their genesis and situation in the regional paleogeography. The conclusion is that these sandstones form a deltaic channel(delta front). To wards the E and NE the become fluvial deposits, to wards the W, Plana de Vic, they become clay and silstones considered as a prodelta

Significado sedimentológico de los niveles con Assilinas de la Formación Armancies (Eoceno medio) y sus equivalentes laterales

In this paper we show some sedimentological characteristics of Assilina beds from Armancies Fm. (middle Eocene) and their lateral equivalents that let us to remark some aspects of their genesis. We arrive to the conclusion that, in occidental sector (Bagá-Campdevanol), ‘las barras de Assilinas’ from the Armancies Fm. are grain flow channels, first sedimented at W of Terrades and after slided, from E to W in a turbidite basin, without any coarse clastic
