Herein are presented the results of detailed bio- (calcareous dinocysts, calpionellids, foraminifers, saccocomids) and chemostratigraphic (δ13C) studies combined with high-resolution microfacies, rock magnetic and gamma-ray spectrometry (GRS) investigations performed on upper Kimmeridgian–upper Valanginian carbonates of Giewont succession (Tatricum, Maly sections, Western Tatra Mountains, Polan...

Seismic, core, drilling, logging, and thin-section data are considered to analyze the reservoir diversity in east, middle, west fan of Liushagang Formation steep-slope zone Weixinan Sag, Beibuwan Basin. Three factors primarily affect differences for systems: (1) Sedimentary mostly control scales characteristics drainage system microfacies. Massive high-quality reservoirs have shallow burial dep...

Coralline red algae are highly abunadant and well diversified in the well exposed carbonate deposits of the Lower Pliocene Shagra Formation at Wadi Wizer, Red Sea coast, Egypt. Lithostratigraphically, the Shagra Formation unconformably overlies the Late Miocene Marsa Alam Formation and underlies the Quaternary deposits. This carbonate facies is dominated by different assemblage of coralline red...

The sediments of the Hartha Formation were deposited during Upper Campanian- Maastrichtian cycle. Due to importance this sequence in terms stratification and economics oil industry, it has been focused on study. present study includes three fields central Iraq within Mesopotaminan Zone, East Baghdad, Balad Kifl fields. This was accomplished by describing 190 thin sections interpreting response ...
