Palynofacies And Kerogen Analysis Of Upper Cretaceous (Early Campanian To Maatrichtian) Enugu Shale And Mamu Formation In Anambra Basin, South-Eastern, Nigeria
The palynofacies and kerogen analysis of the Upper Cretaceous units (Campanian-Maastrichtian) of the Anambra Basin, Southeastern Nigeria was carried out in the studied area. Two major palynofacies types were identified based on the abundance of particulate organic matter. The palynofacies ―A‖ is characterized by abundant phytoclasts, frequent opaqes common amorphous organic matter and carbon to...
متن کاملPalynofacies-based sequence stratigraphy of the Upper Cretaceous strata (Abderaz Formation) in east of Koppeh-Dagh Basin, Northeast of Iran
The Upper Cretaceous strata were studied in a composite stratigraphic section named here Padeha-Baghak section in east of Koppeh-Dagh basin, north east of Iran. In this study, palynostratigraphy, palynofacies and depositional environment history of Abderaz Formation were integrated with sequence stratigraphy. Determination of sea level history and sequence units of the Abderaz Formation using s...
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 کاملTrace Fossils from the Campanian - Maastrichtian Enugu Formation of the Anambra Basin, South-eastern Nigeria: Implications for Paleoenvironmental Interpretation
The Enugu Formation is a member of the Nkporo Group, and forms part of the basal stratigraphic unit of the Anambra Basin in south-eastern Nigeria. The Enugu Formation has been the subject of many studies concerning stratigraphy [1], depositional environments [2; Onuigbo et al. [3], organic geochemistry [4-6], paleoecology [7], palynology [7-9] and ichnology [10]. Nwajide & Reijers [2] were the ...
