“…Most of clay minerals deposited in different sedimentary environments are generally of detrital origin [13,23,40]; and they reflect the original composition of the sources areas, the type of weathering on the adjacent continents, and the process of transport and sedimentation [15,30,43,50,57,59,61,65]. Due to their fine grain size, the clays can be transported large distance by rivers, wind and currents, indicating the dominant trajectories of fine sedi-ments and the suspended matter transport [5,37,26,45].…”

“…Due to their fine grain size, the clays can be transported large distance by rivers, wind and currents, indicating the dominant trajectories of fine sedi-ments and the suspended matter transport [5,37,26,45]. Other studies indicate that the clay mineral assemblages deposited in front of the rivers mouth and toward deep marine areas can be used as dynamic tracers to deduce transport path and the sources areas of clay minerals [5,12,29,43,44,48].…”

The contents and the distribution of clay minerals in modern sediments of the Cadiz bay and the continental shelf have been studied aiming to establish the sedimentary exchange model and the pathways followed by the clay fraction between the bay and the adjoining continental shelf. The most abundant clay minerals in the muddy sediments consist mainly of illite, smectite, interstratified illite-smectite, kaolinite and chlorite. The application of factor analysis method (PCA) to clay minerals data are considered to be useful in the determination of sedimentary transport patterns. The data from clay mineral assemblages, and their distribution map, make possible to establish the fine sediments transport paths in the study area using clay mineral as natural tracers. This model of transport takes in consideration the facies distribution, the supplies sources and the way of fine sediments are incorporated to the marine environment Two flows paths have been established: the outflows coming from Cadiz bay and the littoral zones; and the inflows coming from external marine zones of the bay. These flows are controlled by tidal currents and the morphology of the coast. The action of surge and the marine currents, specially the Atlantic Surface Water flow, are also important in the transport of fine sediments coming from sources located to the north of the study zone.

“…The Subarctic Gyre consists of two subgyres, the Alaska Gyre in the east and the Western Subarctic Gyre in the west (Dodimead et al 1963;Ren et al 2014). In the Aleutian forearc area, the water circulation is dominated by the Alaskan Stream, the Alaska Current, and segments that splay out northwards into the Bering Sea (Naidu et al 1995).…”

“…In the North Pacific and adjoining Bering Sea, provenance studies have explored the mineralogy of bulk sediment (Rex and Goldberg 1958;Morley et al 1987;Nechaev et al 1994) and the <2 μm fraction (Griffin et al 1968;Rateev et al 1969;Heath and Pisias 1979;Naidu et al 1982Naidu et al , 1995Naidu and Mowatt 1983;Blank et al 1985;Underwood and Hathon 1989;Hathon and Underwood 1991), radionuclide tracers in bulk sediment (Nakai et al 1993;Asahara 1999;Pettke et al 2000;Asahara et al 2012), the geochemistry of bulk sediment (Gardner et al 1980;Nakai et al 1993;Weber et al 1996;Serno et al 2014) and the <63 μm fraction (Olivarez et al 1991), and sand composition (Gergen and Ingersoll 1986). Grain-size characteristics have been less commonly used to infer terrigenous sediment supply in this region but have proved to be a pivotal tool (Rea and Leinen 1988;Rea and Hovan 1995;Serno et al 2014).…”

Modern modes of provenance and dispersal of terrigenous sediments in the North Pacific and Bering Sea: implications and perspectives for palaeoenvironmental reconstructions

et al. 2016

During expedition 202 aboard the RV Sonne in 2009, 39 seafloor surface sediment sites were sampled over a wide sector of the North Pacific and adjoining Bering Sea. The data served to infer land-ocean linkages of terrigenous sediment supply in terms of major sources and modes of sediment transport within an over-regional context. This is based on an integrated approach dealing with grain-size analysis, bulk mineralogy and clay mineralogy in combination with statistical data evaluation (end-member modelling of grainsize data, fuzzy cluster analysis of mineralogical data). The findings on clay mineralogy served to update those of earlier work extracted from the literature. Today, two processes of terrigenous sediment supply prevail in the study area: fardistance aeolian sediment supply to the pelagic North Pacific, and hemipelagic sediment dispersal from nearby land sources via ocean currents along the continental margins and island arcs. Aeolian particles show the finest grain sizes (clay and fine silt), whereas hemipelagic sediments have high abundances of coarse silt. Exposed sites on seamounts and the continental slope are partly swept by strong currents, leading to residual enrichment of fine sand. Four sediment sources can be distinguished on the basis of distinct index minerals revealed by statistical data analysis: dust plumes from central Asia (quartz, illite), altered materials from the volcanic regions of Kamchatka and the Aleutian Arc (smectite), detritus from the Alaskan Cordillera (chlorite, hornblende), and fluvial detritus from far-eastern Siberia and the Alaska mainland (quartz, feldspar, illite). These findings confirm those of former studies but considerably expand the geographic range of this suite of proxies as far south as 39°N in the open North Pacific. The present integrated methodological approach proved useful in identifying the major modern processes of terrigenous sediment supply to the study region. This aspect deserves attention in the selection of sediment core sites for future palaeoenvironmental reconstructions related to aeolian and glacial dynamics, as well as the recognition of palaeoocean circulation patterns in general.

“…Mineralogical assemblages determined in the clay fraction have been analyzed. Their origin is clearly detrital or inherited, and may reflect the combined effects of the influence of the source areas, the type of weathering on the adjacent continents, and the process of transport and sedimentation (Millot, 1970;Sawheney & Frink, 1978;Stanley & Liyanage, 1986;Weaver,1989;Chamley, 1989;Naidu et al, 1995). In the present www.intechopen.com Dynamics of Sediments Exchange and Transport in the Bay of Cadiz and the Adjacent Continental Shelf (SW -Spain) 31 study, clay minerals have been used as tracers, since their small size makes them the only particles susceptible of being transported away from the bay, out towards the continental shelf (Gutierrez-Mas et al, 2006;Achab et al, 2008).…”
