The Late Cretaceous-Early Paleocene Shiranish and Aliji formations have been studied in three selected wells Jambur Oil Field (Ja-50, Ja-53, Ja-67) Kirkuk, Northeastern Iraq. This study included lithostratigraphy biostratigraphy. Campanian-Maastrichtian Formation consist mainly of thin marly chalky limestone beds overlain by marl beds, with some representing an outer shelf basinal environment, ...

The KwaZulu-Natal shelf, on the east coast of South Africa, is inhabited by diverse communities demersal fishes; however, previous studies deeper than 30 m have largely investigated these with extractive techniques. Using baited remote underwater videos (BRUVs), this study quantified how depth and substrate type correlated composition fish between 35 100 m, assessed whether displayed congruence...

The Bighorn Basin of northwestern Wyoming preserves one of the most complete records of middle Paleocene to lower Eocene continental biota. The geochronology of this important interval depends partly on numerical calibration of the geomagnetic polarity time scale (GPTS), but the middle and late Paleocene parts of the GPTS have been poorly constrained radioisotopically. A new volcanic ash from t...

The litho-and biostratigraphy of Upper Cretaceous (Gurpi Formation) has been investigated within a well-exposed section at the northern limb of Pey zard anticline, Abnow area, Southern Iran. The studied section consists mainly of grey marl, calcareous pyritic shale, and argillaceous limestones. The Formation unconformably overlies Sarvak Formation and the Tarbur Formation overlies it unconforma...

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...

in this research, calcareous nannofossils of the upper cretaceous deposits of the souteast lar have been investigated. the upper cretaceous deposits have a thickness of 173 meters and consist of thick layers of marl and marly limestone. for introducing calcareous nannofossil assemblages and biozones, 141 slides of the gurpi formation in southeast of lar area have been studies which led to ident...

The degree to which emergent surfaces are correlated in late Asbian carbonate successions Britain and Ireland is assessed by the integration of detailed biostratigraphy diversity trends foraminifers. Data related Trowbarrow Quarry section northern England, provides a reference for upper because its rich assemblages high sampling density. Diversity shown be non-random, possess cyclic behaviour, ...
