The effect of decomposition and diagenesis of sediment organic matter (SOM) on the adsorption of emerging pollutants by the sediment has been seldom addressed. In the present experimental study, artificial sediment was incubated to simulate the natural organic diagenesis process and hence investigate the influence of organic diagenesis on the adsorption of tetracyclines (TCs) by marine sediment...

The Ca, Mg, O, and C isotopic and trace elemental compositions of marine limestones and dolostones from ODP Site 1196A, which range in depth ( 58 to 627 mbsf) and in depositional age ( 5 and 23 Ma), are presented. The objectives of the study are to explore the potential for non-traditional isotope systems to fingerprint diagenesis, to quantify the extent to which geochemical proxies are altered...

During diagenesis, the transformation of unconsolidated sediments into a sandstone is usually accompanied by compaction, water expulsion, cementation and dissolution, which fundamentally control extent, connectivity complexity pore structure in sandstone. As intimately related to fluid flow porous media, it great importance characterize hydrocarbon-bearing comprehensive way. Although convention...

The precise and quantitative characterization of reservoir properties is the key to efficient development tight oil reservoirs. In this paper, taking Chang 8 Member Yanchang Formation in Shuimogou area southern Ordos Basin as an example, sedimentary facies types, microscopic pore structures, diagenesis, influencing factors physical properties, hydrocarbon enrichment law reservoirs are systemati...

The Forties Sandstone Member is an important deep-water reservoir in the Central North Sea. role of depositional characteristics, grain-coating clays, and diagenesis controlling quality sandstones poorly understood. main aim study to understand pore-filling evolution turbidite-channel sandstones. employed a multi-disciplinary technique involving thin section petrography scanning electron micros...

Surface coal mining in Appalachia disturbs hundreds of hectares of land every year with the removal of valuable and ecologically diverse eastern deciduous forests. After the passage of the Surface Mining Control and Reclamation Act in 1977, coal mine operators began planting a variety of grasses and legumes as a fast and economical way to reestablish a permanent vegetative cover to meet erosion...

Surface mining in West Virginia removes the eastern deciduous forest and reclaiming the mined land to a productive forest must consider soil depth, soil physical and chemical properties, soil compaction, ground cover competition, and tree species selection. Our objective was to evaluate tree survival and growth in weathered brown sandstone and in unweathered gray sandstone. Brown and gray sands...

The complex geologic history of sandstone CO2 storage sites can result in separate rock units that control chemomechanical weakening. Here we document the chemical and mechanical changes may occur during injection operations, linking potential instability to diagenesis burial history. Using Southwest Partnership Morrow B sandstone, combined flow either a CO2-rich formation water or through expe...
