Abstract A new theory for formation of flint in the North Sea Danian Ekofisk Formation chalk has been formulated, according to which the flint formed by sedimentation of nano-size α-quartz particles. These α-quartz particles have crystallized in the sea from silicon supplied from dissolution of radiolarians. In the present work this model has been tested by sedimentological and mineralogical ...

The precipitation, growth and stability of mercury sulfide ...

In sulfidic sediments, under conditions of supersaturation with respect to metacinnabar, recent research has shown that mercury precipitates as β-HgS(s) nanoparticles (β-HgS(s)nano). Few studies have examined the precipitation of β-HgS(s)nano in the presence of marine dissolved organic matter (DOM). In this work, we used dynamic light scattering (DLS) coupled with UV-Vis spectroscopy and ...

Pelagic sediment - Wikipedia

Pelagic sediment or pelagite is a fine-grained sediment that accumulates as the result of the settling of particles to the floor of the open ocean, far from land. These particles consist primarily of either the microscopic, calcareous or siliceous shells of phytoplankton or zooplankton; clay-size siliciclastic sediment; or some mixture of these.Trace amounts of meteoric dust and variable ...

Marine litter is a global problem which has been negatively affecting the environment. Plastic materials are the most commonly found marine debris, with potential biological (not only for aquatic organisms but also for humans) as well as socio-economic impacts. Considering that it is an anthropogenic problem, society could play an important role to minimize it. Although a considerable amount ...
