Abstract. The quality and quantity of soil organic matter (SOM) are key elements that impact health climate regulation by soils. Rock-Eval® thermal analysis technique is becoming more commonly used, as it represents a powerful method for SOM characterization providing insights into bulk chemistry stability. In this study, we applied on large sample set from the first campaign (2000–2009) French...
This paper reports on the elemental geochemistry of 47 shale samples from uppermost Hirnantian–lowermost Rhuddanian Tanezzuft Formation, collected drill core (depth interval 20.8–73.2 m) borehole JA-2 at eastern Kufra Basin, SE Libya. Eighteen these were also analysed by X-ray diffraction. study was carried out (i) to search for shales with high total organic carbon (TOC >3 wt%) and associated ...
This research is a follow-up of more comprehensive PhD study on assessment shale gas resources in the northern Song Hong basin that was conducted at Asian Institute Technology (AIT). The basin, typical pull-apart Cenozoic had experienced post-extensional stage accompanied by seafloor spreading from Upper Oligocene to Lower Miocene with its stratigraphy characterised fault-controlled syn-rift co...
Abstract Early Cretaceous and Jurassic sequences in the southwestern Iran host some of largest hydrocarbon reservoirs globe. This study is aimed at evaluating maturity fluids, migration paths, characteristics Pabdeh, Kazhdumi, Garu Sargelu source rocks this region. For purpose, 27 samples Pabdeh Kazhdumi Formations from wells northern part Dezful Embayment were chemically evaluated by Rock–Eval...
The effect of forest management practices on carbon quality is poorly documented. To assess changes in the and stability soil organic (SOC) a temperate upon human activities, we investigated from forests (i) developed following natural regeneration after clearcutting 20 40 years ago, (ii) afforestation an abandoned crop area ago (iii) where regular clear-cut (with wood residues input) was condu...
A pH-sensitive membrane for colon-specific drug delivery was synthesized by the covalent bonding of glycine on the poly(ethylene-co-vinyl alcohol) (EVAL) membrane via isocyanation of surface hydroxyl groups and subsequent conversion to activated ester. The processes of surface modification would not change the membrane structure under the observable detection sensitivity of the scanning electro...
Abstract The Early Jurassic was marked by several episodes of rapid climate changes and environmental perturbation. These culminated during the Toarcian Oceanic Anoxic Event (T-OAE), an episode global warming that led to widespread deposition organic-rich shales. shales NW Europe have also yielded exceptionally preserved fossils marine vertebrates invertebrates, but potential links between occu...
Abstract An extensive subsurface investigation evaluating the geothermal energy resources and underground thermal storage potential is being carried out in southwestern part of Swiss Molasse Basin around Geneva Canton. Among this process, evaluation petroleum source-rock type an important step to understand system responsible some oil gas shows at surface subsurface. This study provides a first...
PURPOSE To evaluate the feasibility and effectiveness of transcatheter embolization by forcible intraarterial injection of a mixture of ethylene vinyl alcohol copolymer (EVAL) and ethanol under microballoon occlusion compared with conventional transcatheter arterial embolization methods in nontumoral swine liver. MATERIALS AND METHODS Nine swine were divided into three groups: embolization wi...
Marine sediments near continental margins contain sedimentary organic matter (SOM) which is subject to the metabolic activity of micro-organisms during early diagenesis resulting in production biogenic methane. This process occurs at microscopic scale and anaerobic conditions. Here, we apply a new numerical approach simulate methane offshore Aquitaine (Bay Biscay) where gas seeps have been rece...
