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,...

in this study biostratigraphy of the upper cretaceous deposits (gurpi formation) in sepidan section located in the interior fars basin (sw iran) was studied. the gurpi formation in this section consists of 360 m lime shale, argillaceous limestone and shale laid continuously on the ilam formation and with a paraconformity under the pabdeh formation. nine genera and 27 species of planktonic foram...

After the Cretaceous/Paleogene boundary (KPB) catastrophic mass extinction event, an explosive evolutionary radiation of planktic foraminifera took place in consequence prompt occupation empty niches. The rapid evolution new species makes it possible to establish high-resolution biozonations lower Danian. We propose two biostratigraphic scales for low-to-middle latitudes spanning first million ...

The Cretaceous pelagic carbonate succession, i.e., Goru Formation was studied in the Chutair Section, Sulaiman Range, representing part of eastern Tethys for paleoenvironment and bio-sequence stratigraphy. Eight planktonic foraminiferal biozones are identified which include: 1. Muricohedbergella planispira Interval Zone; 2. Ticinella primula 3. Biticinella breggiensis 4. Rotalipora appenninica ...

Twenty surface samples were taken from road cuttings along Okpekpe and Imiegba areas located in Benin Flank of Anambra Basin, Nigeria with an aim to establish the biozones, age paleodepositional environments Mamu Formation. Using palynological laboratory standard procedures, shale collected Formation study area prepared analyzed. The recovered marker pollens, spores dinoflagellate cysts are Mil...

Conodonts are the most important fossil remains from the largest Phanerozoic extinction as well as the mass extinction of the late Paleozoic and could be used for exact dating during this period. Triassic deposits located in the Elikah Formation contain exposures in most of the Alborz sections as well as the Zal section in northwestern Iran. In this study, the Elikah Formation was investigated ...

for biostratigraphic studies, based on calcareous nannofossils, a thickness of 480 meters of cretaceous deposits in shushud section (north birjand) has been measured and sampled. the studied section is composed of shale, marl, marine sandstone and sandy limestone. the shale and marl units were more suitable for sampling. according to taxonomical studies, 10 genera and 25 species in shushud sect...
