Ensambles De Microfósiles (Foraminíferos Y Nanofósiles Calcáreos) Cenozoicos Del Subsuelo De La Cuenca De Magallanes, Isla De Tierra Del Fuego, Chile

Abstract: Foraminifera and calcareous nannofossils from washed drill-cuttings of three wells in the Chilean sector of the Magallanes Basin were studied. This contribution aims to identify, characterize and illustrate microfossil assemblages throughout the Cenozoic sedimentary record to integrate foraminiferal and nannofossil data, and improve further biostratigraphic studies in the basin. The analyzed Paleogene and Neogene successions in these three wells correspond to five discrete foraminiferal and nannofossil assembl… Show more

“…The most common calcareous nannofossil species in the recovered assemblages are Chiasmolithus bidens, Chiasmolithus solitus , Fasciculithus tympaniformis , Prinsius martinii , Prinsius bisulcus , Toweius callosus , Toweius eminens , and Toweius pertusus. This assemblage bears similarities with the Lower Uribe Formation from the subsurface of Tierra del Fuego (Mostajo, 1991; Thissen & Pérez Panera, 2021) and the Lower Magallanes Formation from the subsurface of Santa Cruz province (Pérez Panera, 2013) (Fig. 7).…”
