Abstract The first detailed mapping and recording of nannofossils was carried out on Kei Besar Island, Southeast Maluku. This area is mostly composed the Elat Formation, which mainly by intercalated calcarenite calcareous claystone. Total 48 samples were taken three measured sections (Hollat, Ngurdu Mata Hollat). Samples prepared using smear slide method, then observed under a polarized microsc...

The Yamama Formation was studied in three wells (Fh-1, Fh-2, and Fh-3) within Faihaa oil field, south Iraq. Thin sections were by using the polarizing microscope examination order to determine microfossils biozone. Thirty-five species of benthic foraminifera recognized, including four index species. In addition, twelve calcareous green algae two Other fossils that recognized include Gastropoda,...

Investigations on the calcareous nannofossils of Gulneri Formation are being done in northern Iraqi Dokan and Pushen areas, Sulimani, Northern Iraq. In this work, one biozone was established based results a detailed examination used to identify fifty species nannofossils; Quadrum gartneri Biozone (CC11) Lucianorhabdus maleformis (CC12) section, although study, three biozones were suggested; Mic...
