Palaeogene Calcareous Nannofossils from CRP-2/2A, Victoria Land Basin, Antarctica
Rare calcareous nannofossils from the Cape Roberts Project drillhole CRP-2A indicate that this area was episodically invaded by marginal oceanic surface waters during the late and late early Oligocene. These depauperate assemblages lack most of the biostratigraphic index fossils for the Oligocene, but do provide two datums that aid in constraining the age of the section: the last appearance dat...
متن کاملCalcareous Nannofossils from Cape Roberts Project Drillhole CRP-3, Victoria Land Basin, Antarctica
Fossil specimens of the exclusively oceanic calcareous nannoplankton were found only in the upper 200 m of the Cape Roberts Project 3 (CRP-3) cores. These assemblages are depauperate and sporadic in occurrence. The majority of the assemblages contain fewer than 4 species, indicating a severe palaeoecological restriction. The clear domination of these assemblages by reticulofenestrid species, co...
متن کاملCalcareous nannofossils biostratigraphy of the Campanian-Danian interval, Gurpi Formation in the Zagros Basin, SouthWest Iran
This study presents calcareous nannofossils biostratigraphy of the Campanian‒Danian interval at the Gurpi Formation in the southwest of Ilam Province, in the Zagros Basin. The studied sequence of the Gurpi Formation mainly consists of marly shale and limestones. The thickness of Gurpi Formation was measured as approximately 230 m. Forty-five species belonging to twenty-eight genera were recorde...
متن کاملCalcareous Nannofossils in Holocene Surface Sediments of the Persian Gulf
The effect of the paleoclimatic and paleoenvironmental changes on the structure of the bioticcommunities are stronger and better recorded in the shelf area than in the open sea. The present study isdevoted to impact of climatic events on some species of calcareous nannofossils. For this reason, 17samples of surface sediments of the Persian Gulf were studied. Preservation of calcareous nannofoss...
