Abstract
The following is a brief report on a preliminary micropalaeontological research carried out on the Miocene succession of the Porto Torres Basin (Northwestern Sardinia, Italy). Planktonic foraminifers and ostracods from 12 samples collected in the northeastern side of the basin within marls and marly chaotic beds of unknown – dubitatively Langhian – age have been analyzed. From a biostratigraphic viewpoint assemblages unquestionable allowed us to refer the investigated succession to the upper Burdigalian. The ostracod palaeoecological analysis indicates a depositional setting referable to the intermediate part of the outer neritic zone. In addition, since from a general ostracod standpoint the Mediterranean lower Miocene is relatively unexplored, the new biostratigraphic data obtained from this study are discussed.File | Dimensione | Formato | |
