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...

Stochastic Joint Simulation of Facies and Diagenesis: A Case Study on Early Diagenesis of the Madison Formation (Wyoming, USA) — The aim of this paper is to propose an integrated approach to reproduce both facies and diagenetic trends in a static reservoir model based on an outcrop Oil & Gas Science and Technology – Rev.

The source of cement in oilfields is critical to the prediction of the distribution of cements in the reservoirs and also prediction of reservoir quality. The source of mineral forming cements has been determined for the Storrington oolitic carbonate reservoir (Middle Jurassic Great Oolite Formation, Weald Basin, onshore UK) using a combination of petrography, electron microscopy, fluid inclusi...

The diagenetic behavior of proteins, defined as large polypeptides, was examined over a 2-yr period at a mudflat site subject to intense bioturbation. Protein concentrations in the surface sediment correlated well with deposition of algal detritus from the water column. Cellular biomass made up a significant, though likely not a major, component of protein in the sediments; likewise, changes in...

Gale Crater, the Mars Science Laboratory (MSL) landing site, contains a central mound, named Aeolis Mons (informally Mount Sharp) that preserves 5 km of sedimentary stratigraphy. Formation scenarios include (1) complete filling of Gale Crater followed by partial sediment removal or (2) building of a central deposit with morphology controlled by slope winds and only incomplete sedimentary fill. ...

Diagenesis is a double-edged sword of geochemical recordings. It makes us always doubt about the representativeness many indicators, especially isotope and mineral related. also provides window to explore biogeochemical processes at water–rock interface, which are related interactions between hydrosphere, biosphere, lithosphere. In this study, we identified microbial early diagenesis in lacustr...
