Marine sediment with an input of particulate organic matter was incubated to simulate the early aging process. On the sediment after various incubation periods, adsorption and desorption tests were conducted for three selected organic micropollutants: bisphenol A (BPA), 17α-ethinyl estradiol (EE2), and phenanthrene (Phe). The results showed significant sediment organic matter (SOM) decompositio...

Although recent studies have revealed more widespread occurrences of magnetofossils in pre-Quaternary sediments than have been previously reported, their significance for paleomagnetic and paleoenvironmental studies is not fully understood. We present a paleo- and rock-magnetic study of late Miocene marine sediments recovered from the Guadalquivir Basin (SW Spain). Well-defined paleomagnetic di...

Abstract The grain size of clastic rocks is one the most important structural characteristics sediments, which can directly reflect hydrodynamic conditions ancient sedimentary period. preparation conventional rock particle samples usually done by hand wet grinding with a hammer experienced experimenter. For fine-grained rocks, method for preparing has disadvantages long time and low efficiency....

This study aims to identify favorable oil–gas reservoir facies in the Chishan group of the Wubao fault zone (Gaoyou sag, Subei basin, China) using the methods of outcrops and cores observation, granularity analysis, scanning electron microscope, log data, etc. The results suggest that the Chishan group in the studied area mainly develops desert sedimentary system, and contains five kinds of fac...

Cohesion is the main inter-controlled factor for stability of fine-grained sediments in debris flow, and plays an important role flow hazard early warning. At present, there no cohesion rapid remote sensing detection model, which seriously affects development quantitative evaluation on stability. How to use quickly detect has become scientific issue. Therefore, strengthening research hyperspect...

Experimental and field observations evidence the effects of capillarity in narrow pores on inhibiting thermodynamic stability gas hydrates controlling their saturation. Thus, precise estimates hydrate global inventory require models that accurately describe sediments. Here, an equilibrium model for formation sediments accounts capillary inhibition is developed validated against experimental dat...

A Silurian shift in fluvial stratigraphic architecture, coincident with the appearance of terrestrial vegetation fossil record, is traditionally cited as evidence for exclusively shallow, braided planforms pre-vegetation rivers. While recent recognition deep, single-thread channels pre-Silurian strata challenge this paradigm, it unclear how these rivers maintained stable banks. Here, we reconst...

this paper provides an overview on obtaining low-carbon ultra-fine grained dual-phase steels through rapid intercritical annealing of cold-rolled sheet as improved materials for automotive applications. a laboratory processing route was designed that involves cold-rolling of a tempered martensite structure followed by a second tempering step to produce a fine grained aggregate of ferrite and ca...
