In many northern temperate regions, the water color of lakes has increased over the past decades (“lake browning”), probably caused by an increased export of dissolved organic matter from soils. We investigated if the increase in water color in two lakes in Norway has resulted in increased burial of organic carbon (OC) and mercury (Hg) in the sediments and if the Hg was prone to methylation. La...

The bouffia Bonneval at La Chapelle-aux-Saints is well known for the discovery of the first secure Neandertal burial in the early 20th century. However, the intentionality of the burial remains an issue of some debate. Here, we present the results of a 12-y fieldwork project, along with a taphonomic analysis of the human remains, designed to assess the funerary context of the La Chapelle-aux-Sa...

Abstract Sedimentary pyrite formation links the global biogeochemical cycles of carbon, sulfur, and iron, which, in turn, modulate redox state planet's surficial environment over geological time scales. Accordingly, sulfur isotopic composition (δ34S) has been widely employed as a geochemical tool to probe evolution ocean chemistry. Characteristics depositional post-depositional processes, howev...

Current research on diagenesis and its evolution focuses mainly sandstone reservoirs. Conventional oil gas reservoir observation techniques for characterizing shale reservoirs are limited, comprehensive nanoscale pore variations, of reservoirs, especially immature low-maturity marine is relatively scarce. To reveal the shale, geochemical mineral analyses, quantitative characterization structure...

The thick Upper Cambrian Xixiangchi dolostones, developed in the Sichuan Basin, are an important deep exploration target, but their genesis is still controversial, which hinders predicting porous dolomite distribution and related potential hydrocarbon play. Herein, based on observation sampling of field outcrops, combined with a microscopic thin section analysis, cathodoluminescence geochemical...

The degree of mine burial is a crucial factor in Mine Counter Measure (MCM) mission planning, having a significant effect on sensor range and effectiveness. The ultimate goal of this project is to provide an mine burial prediction fleet aid for operational Navy MCM decision making that incorporates recent research in burial mechanisms and seafloor sediment behavior. This predictive tool should ...

Disturbance can fragment plant clones into different sizes and unstabilize soils to different degrees, so that clonal fragments of different sizes can be buried in soils at different depths. As a short-term storage organ, solon internode may help fragmented clones of stoloniferous plants to withstand deeper burial in soils. We address (1) whether burial in soils decreases survival and growth of...

Adipocere is a decomposition product comprising predominantly of saturated fatty acids which results from the hydrolysis and hydrogenation of neutral fats in the body. Adipocere formation may occur in various decomposition environments but is chiefly dependent on the surrounding conditions. In a soil burial environment these conditions may include such factors as soil pH, temperature, moisture ...

Colluvial soils are enriched in soil organic carbon (SOC) in comparison to the soils of upslope areas due to the deposition and progressive burial of SOC. This burial of SOC has important implications for the global carbon cycle, but the long-term dynamics of buried SOC remain poorly constrained. We addressed this issue by determining the SOC burial efficiency (i.e. the fraction of originally d...
