Depositional Enviroment And Origin Of Deformation Structures In The Upper Cretaceous Facies Of Enugu Area, South Eastern Nigeria
The Upper Cretaceous facies of Enugu Area are part of the sequence in the Anambra Basin of Southeastern Nigeria. These include the Enugu Shale, Mamu Formation, Ajali Sandstone and Nsukka Formation. The deformation structures within the Upper Cretaceous in Enugu area were dominant to sandstones of the Marnu Formation. The white silty fine sandstone, muddy fine sandstone and heteroliths of this f...
متن کاملFacies and Depositional Environments of Cretaceous Siliciclastic Sediments in Al Bauga Area , Northern Sudan
The outcropping Cretaceous siliciclastic sediments in the Al Bauga area in Northern Sudan reach a maximum thickness of about 30 meter. They rest with angular unconformity on tilted Precambrian basement rocks and are capped by Tertiary-Quaternary basalts forming a type of nonconformity. The sedimentary sequence was subdivided into three major units separated by two disconformities. The lower uni...
متن کاملMagnetic Characteristics of Carboniferous Continental Depositional Systems: Implications for the Recognition of Depositional Hiatuses
Quaternary magnetic studies have provided the conceptual framework to bridge magnetic studies into ancient systems. In cases where environmental materials have been subjected to diagenetic alteration two questions come to mind: 1) What part of the magnetic signal is preserved in the rocks; and 2) can the preserved signal be used to infer/identify magnetic patterns that are characteristic of the...
متن کاملOnlap, ottlap, and the origin of unconformity-bounded depositional sequences
Christie-Blick, N., 1991. Onlap, ofttap, and the origin of unconformity-bounded depositional sequences. Mar. Geol., 97: 35-56. Unconformity-bounded depositional sequences represent the fundamental building blocks of sedimentary successions. They are typically characterized by onlap at the base and by offlap at the top, and they tend to be markedly asymmetrical, with onlap accounting for a large...
متن کاملAssociation of the Flow Units with Facies Distribution, Depositional Sequences, and Diagenetic Features: Asmari Formation of the Cheshmeh-Khush Oil Field, SW Iran
The Oligo-miocene Asmari formation is one of the most important hydrocarbon reservoirs in the southwest of Iran. In order to evaluate reservoir quality and the factors controlling reservoir properties, detailed geological and petrophysical studies were carried out on 242 m of core samples from Asmari reservoir. This study is a part of a larger project that examines depositional history and rese...
