Pelagic red clay, also known as simply red clay, brown clay or pelagic clay, is a type of pelagic sediment. [1] [2] Pelagic clay accumulates in the deepest and most remote areas of the ocean.

Red clay, also known as either brown clay or pelagic clay, accumulates in the deepest and most remote areas of the ocean.

May 18, 2012 · The bacteria living in these sediments were respiring the oxygen but at a slower rate than the supply of organic material dropping out of the water column, allowing these ancient deep marine sediments to remain oxygenated.

THE COMPOSITION OF THE RED CLAY F. W. CLARKE In the volume upon Deep Sea Deposits, issued as one of the reports of the "Challenger" expedition, there are published twenty- five analyses of the "red clays."' This sediment is now recognized as the most extensive and important of all oceanic deposits, for it covers

May 8, 2018 · red clay (brown clay) A brown or red, very fine-grained, deep-sea deposit composed of finely divided clay material that is derived from the land, transported by winds and ocean currents, and deposited far from land in the deepest parts …

Jul 13, 2016 · It was recognized a long time ago that deep-sea “red” clays essentially represent residual sediment following dissolution of biogenic components [e.g., Berger and Winterer, 1974]. Oceanographic features that best discriminate clay from other lithologies are bathymetry, and the co-variant ocean surface salinity and temperature (Figures 10 a ...

Pelagic clay, also commonly known as deep-sea clay or abyssal red clay, is a fine-grained lithogenous deposit, the bulk of which is clay and silt with minor amounts of sand that is unique to the deep ocean (generally below 4,000 m).

May 30, 2017 · Dominant types of deep-sea sediment are carbonate “oozes” and “Red Clay” (the residue after dissolution of carbonate ooze, commonly at depths well below 4 km). The calcareous oozes cover almost half of the deep seafloor (i.e., about one-third of the solid Earth); Red Clay covers about 40% of the deep seafloor (i.e., only slightly less ...

Red clays represent the residual sediment type formed in deep-sea areas of low biological productivity occurring beneath the Carbonate Compensation Depth (CCD) where inputs of terrigenous material are low.

Jul 1, 2021 · Here we report very low coercivity biogenic magnetite in red clay from Ocean Drilling Program (ODP) Site 777 in the northern Mariana Basin. Analyzed sediment showed non-interacting, stable single-domain-like magnetic behaviors.
