A Reassessment of Petrochemistry of ~1.2 Ga Tonalitic Rocks of the Northern Tugela Terrane, Natal Metamorphic Belt, South Africa: Further Constraints on the Evolution of This Belt

Geological Journal, EarlyView.
Our petrochemical studies on ~1.2 Ga granitoids of the Natal Metamorphic Belt, South Africa, do not suggest any property similar to Phanerozoic‐style subduction‐related granitoids. Plot of Kotongweni Tonalite in Y versus Sr diagram (after Moyen 2011), note that most samples have Sr/Y < 50.

Characteristics of Gravity Flow Deposits in the Benin Basin (Benin) and Implications for Oil and Gas Exploration

Geological Journal, EarlyView.
This study reveals that the underexplored Benin Basin features a narrow shelf and steep slope, which promoted the development of multi‐phase, stacked channel‐lobe complexes. These gravity flow deposits, further enhanced by bottom current reworking, reveal a significant undiscovered Upper Cretaceous stratigraphic play with considerable petroleum ...

Tectono‐Sedimentary Evolution of the Neogene İnegöl Basin (NW Anatolia): Constraints on Transtensional Basin Development at the Junction of the Western Anatolian Extensional Province and the North Anatolian Fault Zone

Geological Journal, EarlyView.
The study outlines the tectono‐sedimentary evolution of the İnegöl Basin in north‐western Anatolia. Basin formation was controlled by interacting extensional and strike‐slip fault systems linked to uplift of the Uludağ Massif. Terrestrial sedimentation from the Miocene to Pleistocene is reconstructed using abundant fossil mammal assemblages that ...

Integrated astrochronology, sequence stratigraphy, and chronostratigraphy of a shallow marine sandy mudstone (Lower Jurassic, Redcar Mudstone Formation, Cleveland Basin, UK)

Sedimentologika
Cyclostratigraphy and sequence stratigraphy are cornerstone disciplines of modern sedimentary geology but are not commonly applied to the same study sections.

STRATIGRAFIA SEQUENZIALE DELLA SUCCESSIONE OLIGO-MIOCENICA DELLE LANGHE, BACINO TERZIARIO LIGURE-PIEMONTESE

Rivista Italiana di Paleontologia e Stratigrafia, 2017
The Piedmont Tertiary Basin (PTB) is bounded southwards and westwards by the Western Alps, and northwards by the north-western end of the Apennines. It develops internally to a south-dipping suture zone, on a basement consisting of allochthonous alpine ...

Local Structures of Se and Br in Cretaceous–Paleogene Boundary Sediments and Concentration Effects of Ferrihydrite Originating From Impact Ejecta

Geological Journal, EarlyView.
Chemical states of Se and Br atoms in the KPg boundary sediments from Stevns Klint were studied using XAFS spectroscopy. The high concentrations of Se4+ could become an index of the degree to which the global environment was soiled with dust and ash derived from impact ejecta or volcanic eruptions.

Ordovician sequence stratigraphy and correlation in the Middle-Upper Yangtze region, South China

China Geology, 2018
: The precise correlation of the Ordovician successions in different facies is difficult due to the complex changes of the tecto-paleogeography in South China. Based on previous studies, the authors recognized 10 3rd grade sequences, i. e., Osq1 to Osq10
