The definition of pre-Messinian source rocks in the eastern Mediterranean is paramount importance for hydrocarbon exploration because ability salt to act as a high-quality seal rock. This research evaluates organic geochemical features Upper Miocene (Tortonian—Messinian) sedimentary succession onshore Crete Island, Greece. study employs original (Messinian, Agios Myron Fm) and published (Torton...

â â â  â  â â â â â â â  abstract â  the abtalkh formation in the kopeh-dagh basin in northeastern iran with an age of late cretaceous (turonian – santonian) is selected to evaluate resolution of magnetic susceptibility for assessing sea level fluctuations. thirty-nine shale samples were collected and studied for magnetic susceptibility and palynology. assuming the average ms magnitude as the...

The Mesoproterozoic Xiamaling Formation (∼1.4 Ga) is considered to be a set of promising strata for shale oil and gas exploration production in the Yanliao Basin, North China Craton. This study aimed investigate organic matter accumulation mechanism, hydrocarbon generation expulsion characteristics Formation, using various methods, including scanning electron microscopy, rock-eval pyrolysis, el...

Abstract Facies of rifting basins reflect different depositional environments from deep to shallow conditions. The present study focuses on subsurface facies characterization and source rock assessment Kareem Rudeis rocks in six wells lying the central Gulf Suez. distribution lithologic patterns delineated through several constructed maps. Porosity cross-plots formations determine minerals poro...

This study presents the results derived from micropaleontological and organic geochemical analyses of mud breccia samples obtained (through gravity coring) five volcanoes (Gelendzhik, Heraklion, Moscow, Milano, Leipzig) located at Olimpi volcano field on Mediterranean Ridge accretionary complex. A thorough calcareous nannofossil semi-quantitative analysis was performed to determine biostratigra...

Gas chromatography (GC), gas chromatography-mass spectrometry (GC/MS), supercritical fluid chromatography (SFC), elemental analysis, infrared absorption spectroscopy (IR), thermal analysis (TG/DTA), Rock-Eval pyrolysis, as well as viscosity and density analysis revealed that oil sands from Qaidam basin, Qinghai Province of China, are highly concentrated in light components (£C23), with saturate...

This study relates to the input and fate of fossil organic matter (FOM) in the modern environment, and focuses on two experimental watersheds overlying Jurassic marls: Le Laval and Le Brusquet (1 km 2 in area), located near Digne, Alpes-de-Haute-Provence, France. Considering that FOM delivery is mainly a result of different processes affecting sedimentary rocks [(bio)chemical and mechanical wea...
