“…In deeper water, in the prodelta environments, the sediments are the finest and χ fd %, χ ARM /χ, and χ ARM /SIRM reach their highest values. A similar fining trend of ferrimagnetic minerals has been observed in the suspended sediments and floodplain sediments of the Yangtze River [ Li et al ., ], as well as in the suspended estuarine sediments of the Yangtze Estuary [ Dong et al ., ].…”

We conducted a mineral magnetic study of river bank and subaqueous delta sediments from the Red River, in order to examine the role of sedimentary sorting on the variation of sedimentary magnetic properties from source to sink. The magnetic mineralogy mainly consists of magnetite and hematite. Bulk sediment particle‐size variations have a strong influence on magnetic properties, with the frequently used magnetic parameters χfd%, χARM, χARM/χ, and χARM/SIRM exhibiting positive correlations with the <4 µm fraction, while S‐ratios are negatively correlated with this fraction. Compared with river bank sediments and shallow shoreface (<5 m water depth) sediments, sediments from the deeper (>5 m water depth) part of the subaqueous delta have lower χ and SIRM values, a finer ferrimagnetic grain‐size and higher proportions of hematite, consistent with selective loss of coarse ferrimagnetic grains on the source‐to‐sink pathway. We suggest that variations in magnetic properties in response to particle‐size compositions and therefore depositional environment changes should be carefully addressed when magnetic proxies such as χARM/SIRM are used in the study of coastal and marine environmental changes (e.g., sea‐level change). In such cases, the combined use of magnetic properties and geochemical indicators, such as Al/Ti ratio, may provide better results for paleoenvironmental reconstruction.

“…Most of the Changjiang sediment loads come from the upper reaches (from the origin to Yichang) (Dai and Tan, ; Yang et al ., ; Yang et al ., ). The Changjiang flows in central and east China along the temperate to subtropical monsoon climate regions with about 1100 mm annual precipitation (Saito et al ., ; Chen et al ., ; Li et al ., ). The majority of the Changjiang basin lies in the Yangtze Craton with basement rocks including carbonate rocks, biotite‐hornblende gneisses, tonalites, trondhjemites, granodiorites, basalt, and basic and ultra‐basic rocks (Pan and Dong, ; Chen et al ., ; Yang et al ., ; Yang et al ., ).…”

The influence of hydrodynamics on the chemical composition of sediments is based on the uneven distribution of element abundances in different size fractions. In this study, 72 size-fractional sediments from the Huanghe (Yellow River) and Changjiang (Yangtze River) riverbeds were measured with XRD, SEM, ICP-AES and ICP-MS. The analysis results show that the mineral and chemical characteristics change with grain size in the Huanghe and Changjiang sediments. According to the principal components analysis, three independent geochemical factors were found. The first factor elements, Zr, Hf, Th, U, Y, La and TiO 2 are influenced by the existence of heavy minerals. The second factor elements, Al 2 O 3 , alkalis, alkaline earth (excluding Ca and Sr) and most of the transitional metals are dominated by clay minerals. The third factor group includes Ca and Sr, which were controlled by calcium-bearing mineral contents and chemical weathering intensities

“…China's rapid development of industry is in the last decades is attracting more attention in terms of pollution major rivers and coastal areas hydro ecosystems. China provides a huge mass of terrigenous sediments to the E3S Web of Conferences 234, 00048 (2021) https://doi.org/10.1051/e3sconf/202123400048 ICIES 2020 ICIES'2020 marginal seas of East Asia and the north-western Pacific, which makes a significant impact on the marine sedimentation, primary production and, in general, biogeochemical cycles [8,12,13,14,15]. A number of studies to determine and compare magnetic properties in different sedimentogenesis environments [13] covered the Changjiang (Yangtze) and Huanghe (Yellow) Rivers, the topsoil of Loess Plateaus, Taklimakan desert sand and dust storms.…”

Long-term and large-scale man-made activity in the mining areas affects to all components of the biosphere. The result of mining impact on hydroecosystems is addition to natural sources of sedimentary material technogenic components in large volumes. Magnetic particles are one of technogenic components which come with surface run-off to the river bed. We have studied the content of magnetic particles in the sediments of the south Ukraine rivers: the Inhulets River and the Inhul River ‒ the tributaries of the Dnieper and the Southern Buh, respectively. The Inhulets River flows along the Kryvyi Rih iron ore deposit, parallel the river there is a chain of open-pits, mines, mining and processing plants, a metallurgical plant. The results of our research were demonstrated within the Kryvyi Rih industrial agglomeration a number of magnetic particles in the sediment samples varies from 59,5% to 2,1%. Upstream from the Kryvyi Rih city on 10-15 km a number of magnetic particles is within 1,5%. Based on numerous sources of literature and own researches, it has been determined that detection of magnetic particles and properties is a convenient, cheap, quick and informative method of technogenic pollution studying of river sediments and also mirror the industrial history of the region.
