20/11/2012#0183;#32;42Sedimentation in the Ocean Deepsea Sedimentation has two main sources of sediment: external terrigenous material from the land and internalbiogenic and authigenic from the sea. Sedimentation in the Deep Sea 5. Grain size and current velocity affect the deposition and erosion of sediment. Smallest and largest particles behave similarly with respect to transportation and erosion
Most Recent Atlantic Ocean deepsea clay is detritus from the continents. The formation of minerals in situ on the ocean bottom is relatively unimportant in the Atlantic but may be significant in parts of the southwestern Indian Ocean.
The clay mineral assemblage of marine sedimentary basins is the product of multiple factors that include (i) vertical movements of the adjacent continental areas and associated sealevel changes
23/5/2017#0183;#32;Over wide areas in the deepest part of the ocean, clay minerals are predominant and most if this clay is terrestrial in origin. Because clay is brought by the currents, it settles everywhere in the oceans, but in certain area such as pelagic silica and carbonate sediment, the minerals dominate over clay. (see also: Endangered Seorses) B. Pelagic Sediment. Some may call this sediment
14/6/2011#0183;#32;The majority of carbon sequestration at the Earths surface occurs in marine continental margin settings within finegrained sediments whose mineral properties are a function of continental climatic conditions. We report very high mineral surface area (MSA) values of 300 and 570 m2 g in Late Cretaceous black shales from Ocean Drilling Program site 959 of the Deep Ivorian Basin that vary on
Claymineral distributions in the Arctic Ocean and the adjacent Eurasian shelf areas are discussed to identify source areas and transport pathways of terrigenous material in the Arctic Ocean. The main clay minerals in Eurasian Arctic Ocean sediments are illite and chlorite. Smectite and kaolinite occur in minor amounts in these sediments, but show strong variations in the shelf areas. These

Georges Millots first and last reviews were, therefore, devoted to clay sedimentation in marine environments where he defined the widely used terms of heritage, transformation and neoformation. This underscores the interest and energy that he deployed throughout his scientific life in order to better understand clay mineral sedimentation in the ocean in the course of the earths geological history.
Biogenic sediments are widespread on the sea floor, covering one half of the shelves and more than one half of the deep ocean bottom (total ~55%.) They constitute ~30% of total volume of sediment being deposited. Lithogenic Sediments: Detrital products of preexisting rocks (igneous, metamorphic, sedimentary) and of
19/1/2011#0183;#32;Problem of the distribution of clay minerals in water areas of the World Ocean and their relation to different (humid, arid, and volcanosedimentary) types of lithogenesis is considered. It is shown that layer silicates can be used as index minerals for distinguishing types of lithogenesis under conditions of marine sedimentation. Humid marine lithogenesis is represented by sediments of the
The clay mineralogy of 235 surface sediment samples from the western Indian Ocean reveals many sedimentary sources and processes: (1) some areas, mainly in the central Indian Ocean, where very little sediment transport is involved, have smectiterich clays derived from the alteration of in situ submarine basalts. (2) In many other areas, the mineralogy is significantly influenced by several
responsible for the constitution of clay suites in most recent sediments of the world ocean. Illite, chlorite, associated quartz, feldspars and various dense minerals, commonly called primary...

In natural settings, occulation of clay minerals occurs dominantly in estuaries and deltas where uvial (, approximately 0psu) waters are mixed with marine waters (approximately 30psu). This process of sedimentation is of interest as it strongly inuences the distribution of negrained sediment in these marginalmarine locales.
