  • 摘要:During Aquitanian-Burdigalian times, temperate-type carbonate-siliciclastic successions were deposited in basins located on the grabens and half–grabens along the Oligo-Miocene Sardinia Rift Basin (Sardinia, Italy). In one of these basins, the Isili Basin, rhodalgal/bryomol limestone was deposited in a temperate-type carbonate depositional system in which a shallow carbonate factory, a marginal tributary belt and a main channel were identified. The Isili Limestone is herein described in terms of biogenic components and taphonomic characterization. In order to understand the palaeoecological settings and the related palaeoceanographic controls, the coralline algal assemblages have been differentiated according to coralline growth-forms, rhodolith shapes, rhodolith inner structures, and taxonomic composition
