“…For evaluating the contribution of the plateau erosion to the material in the middle and lower reaches and estuaries, some comparisons of the geochemical characteristics between different river stretches are made (the compared data are from Ahmad et al 1998;Yang and Li 1999;Singh and France-Lanord 2002;Yang et al 2002aYang et al , b, 2004Yang et al , 2007Borges et al 2008;Singh 2010;Garzanti et al 2010;Alizai et al 2011). CaO concentrations in the middle and lower reaches of the Yangtze River are remarkably lower than those in the upper reaches.…”

“…Element geochemistry plays an important role in the studies of paleoenvironment, paleoclimate changes, and provenance tracing, and Nd isotope is supposed to be a good provenance tool, as it is very poorly influenced during the processes of weathering, transport, and diagenesis (e.g., Nesbitt 1979;Fleet 1984;Goldstein et al 1984; Goldstein and Jacobsen 1988;Taylor and McLennan 1985;McLennan 1989;Revel et al 1996;Najman 2006). In recent years, major and trace elements and Sr-Nd isotopic tracing of sediments have been widely used in riverine geochemical researches in the Tibetan Plateau-Himalayan orogen, and these studies have mainly focused on the middle and lower reaches of rivers (e.g., Ahmad et al 1998;Dekov et al 1998;Zhang et al 1998;Gaillardet et al 1999;Yang and Li 1999;Galy and FranceLanord 2001;Clift and Blusztajn 2005;Clift et al 2002;Singh and France-Lanord 2002;Yang et al 2002aYang et al , b, 2004Yang et al , 2007Lee et al 2003;Dalai et al 2004;Garzanti et al 2005Garzanti et al , 2010Chappell et al 2006;Mukherjee et al 2007;Borges et al 2008;Singh et al 2008;Li et al 2009;Rahaman et al 2009;Galy et al 2010;Hoang et al 2010;Singh 2010;Alizai et al 2011).…”

We investigated the geochemical characteristics of major, trace and rare earth elements and Sr-Nd isotope patterns of bed sediments from the headwaters and upper reaches of the six large rivers draining the Tibetan Plateau (the Jinsha River-Yangtze, Lancang RiverMekong, Nujiang River-Salween, Huang He-Yellow, Indus, and Yarlung Tsangpo-Brahmaputra). By using Ca/ Al versus Mg/Al, La/Sc versus Co/Th, and 87 Sr/ 86 Sr versus e Nd (0) binary differentiation diagrams of provenance, some typical contributors to the different catchment sediments can be identified. In the Three-River (the Jinsha, Lancang, and Nujiang Rivers) tectonomagmatic belt, acidic-intermediate-acidic volcanic rocks are very important provenance of sediments. Carbonate rocks and Permian Emeishan basalts are dominant in the Jinsha River. The Yellow River sediments have similar geochemical characteristics with loess in catchments. The Indus and Yarlung Tsangpo Rivers sediments are mainly from ultra-K volcanic rocks and Cenozoic granitoids widely distributed in the Indus-Yarlung suture. The intensity of chemical weathering in these river catchments is evaluated by calculating the chemical indices of alteration (CIA) of sediments and comparing them with bedrocks. The CIA values of the six river sediments are from 46.5 to 69.6, closing to those of bedrocks in the corresponding catchment, which indicates relatively weak chemical weathering intensity. Lithology, climate, and topography affect the chemical weathering intensity in these river catchments.

“…A series of methods exist for the analysis of the provenance of rocks, such as variation of seismic waves, glutinite body thickness statistics, ZTR index distribution, detrital composition observation, geochemistry analysis, fission-track and identification of pollen types (Yalcin, 2008;Yang et al, 2009;Carroll et al, 2010;Zheng et al, 2013;Xu et al, 2013;Zhang et al, 2014;Kang et al, 2014;Zhao et al, 2014). Among these methods, the method involving the use of a heavy mineral combination and its content variation of clastic rocks to both trace the provenance and obtain the source rock information has been widely applied (Cao et al, 2013;Yang et al, 2013).…”

Heavy minerals are extremely sensitive indicators of provenance. Applying the methods of heavy mineral combination analysis, content distribution analysis, SPSS statistical component analysis, and correlation analysis, 18 heavy minerals are identified in the northwestern margin of the Junggar Basin (NW Junggar). According to the analysis of the heavy mineral characteristics and coefficients, 4 heavy mineral combinations are developed in the study area: Zircon-tourmaline-monazite-apatite-anatase, rutile-ilmenite-leucoxene-apatite-galenite, hematite-limonite-pyrite, and magnetite-epidote-hornblende. Previous results predicted that source rocks consist of intermediate-acidic magmatite, sedimentary rocks and metamorphic rocks, and intermediate-acidic magmatite is considered to be the main source rock. Furthermore, combined with the geological background of NW Junggar, Qier-Halaalat Mountain, which belongs to the Zaire Mountain front, is shown to be the provenance of the study area. The main sources of sediments are flesh-red granite, grey and greyish-green andesite, andesitic-porphyrite, grey and grayish-black tuff, siltstone, and sandstone of the Lower Carboniferous Tailegula Formation. Additionally, because of the high content of the angular-subangular and subangular-subrounded heavy mineral grains, these heavy minerals are both from near and distal provenance, with most being near-provenance deposits. During the process of provenance propulsion on the margin of the basin, clastics are mixed together and affected by regional dynamic metamorphism, which is probably the main reason for the existence of the metamorphic component.

“…A large variety of methods, such as elemental and isotopic geochemistry [1][2][3][4][5][6][7][8], heavy mineral [9,10], magnetic mineral [11][12][13], U-Pb dating of detrital zircons [14,15] and some other methods play an important role in provenance investigations of river sediments. Among these methods, Sr-Nd isotopic systemis widely applied to provenance study of rivers since they basically do not fractionate during weathering, erosion and transport.…”

This study examines the effects of hydrologic sorting and mixing of sources on the Sr-Nd isotopic compositions of suspended sediments at different water depths. The samples were collected from three layers (surface, middle and bottom) at Datong hydrological station of Yangtze River during the flood season of 2010. Our results show that, 87 Sr/ 86 Sr values decrease from surface to bottom, ranging from 0.730332 to 0.720857. ε Nd (0) values range from −14.75 to −10.09, with surface sediments being the most negative. The isotope composition at the middle layer can best represent the mean isotopic composition of the total suspended sediments transported by a river. It is believed that the stratification of Sr-Nd isotope is attributable to mixing of sediments from different sources due to hydrological sorting. Sediments from the upper stream are found to be coarser, and tend to contribute more to the lower water column. Although Sr-Nd isotope is a well acknowledged tool to trace sediment provenance, the current study suggests that the grain size of the samples and the sampling locations should be taken into consideration when applying this method to provenance study.Yangtze River, suspended sediment, Sr and Nd isotope, stratification
