The Sichuan Basin is one of the largest petroliferous basins in China. continental fluvial‒lacustrine sediments Upper Triassic Xujiahe Formation and Lower Jurassic Zhenzhuchong yield diverse fossil organisms host most important gas reservoirs basin. However, paleontological implication for paleoenvironment hydrocarbon source less documented. Here, we report, first time this basin, results from ...

Abstract Palynofacies is based on the different types of dispersed/sedimentary organic matter (DOM/SOM) and has been used as a proficient proxy for palaeoclimatic reconstructions in sedimentary deposits various time spans. It also acknowledged an effective tool domains like sequence biostratigraphy, palyno-biostratigraphy, palaeodepositional history, identification depositional processes, oxic–...

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...

A sedimentological, stratigraphical and palynological study was conducted on the upper Cretaceous (Campanian) Mesaverde Group over 27.5 km of a north-south-orientated outcrop belt in the northern Bighorn Basin, Wyoming. During the Campanian, the study area lay in the western part of the Cretaceous Western Interior Seaway. The study aims to provide a stratigraphic and paleoenvironmental analysis...

The Middle Jurassic was a time of marginal to shallow shelf settings dominated by organic matter-rich deposition in northern Egypt, southern Tethys. Paleoenvironmental and sequence stratigraphic reconstructions are paramount significance for better understanding basin history related reservoirs source rock units. For this purpose, detailed palynomorph palynofacies analysis the Khatatba Formatio...
