“…These different end-members may be induced by mineralogical sorting of different minerals 328 bearing Na such as albite (Garzanti et al, 2010;2011) The isotopic composition of carbonates is shown in Figure 10 and is in agreement with 419 published data for bedload samples from the Ganga basin (Galy et al, 1999 Chambal sediment contribution to the Ganga sediment load also highlights that even in these 553 large systems, the transfer of suspended sediments can be rapid and vary on an annual basis. 554…”

1We present an extensive river sediment dataset covering the Ganga basin from the Himalayan 2 front downstream to the Ganga mainstream in Bangladesh. These sediments were mainly 3 collected over several monsoon seasons and include depth profiles of suspended particles in 4 the river water column. Mineral sorting is the first order control on the chemical composition 5 of river sediments. Taking into account this variability we show that sediments become 6 significantly depleted in mobile elements during their transit through the floodplain.

“…Calcite and dolomite are also abundant. For detailed mineralogical analysis see 263 Garzanti et al (2010) and Garzanti et al (2011). In the Ganga River basin, sediment load 264 increases bottomward by a factor of 2 to 3 between the shallowest and deepest samples.…”

International Ocean Discovery Program Preliminary Report

International Ocean Discovery Expedition 354 to 8°N in the Bay of Bengal drilled a seven site, 320 km long transect across the Bengal Fan. Three deep-penetration and an additional four shallow holes give a spatial overview of the primarily turbiditic depositional system that comprises the Bengal deep-sea fan. Sediments originate from Himalayan rivers, documenting terrestrial changes of Himalayan erosion and weathering, and are transported through a delta and shelf canyon, supplying turbidity currents loaded with a full spectrum of grain sizes. Mostly following transport channels, sediments deposit on and between levees while depocenters laterally shift over hundreds of kilometers on millennial timescales. During Expedition 354, these deposits were documented in space and time, and the recovered sediments have Himalayan mineralogical and geochemical signatures relevant for reconstructing time series of erosion, weathering, and changes in source regions, as well as impacts on the global carbon cycle. Miocene shifts in terrestrial vegetation, sediment budget, and style of sediment transport were tracked. Expedition 354 has extended the record of early fan deposition by 10 My into the late Oligocene.

“…Relative to litho-feldspatho-quartzose metamorphiclastic Ganga-Brahmaputra sediments, derived dominantly from the Himalaya but partly also from the Indian foreland and taken here as a reference for foreland-basin sands (Garzanti et al, 2010), Mesopotamian sands show concentration ofs Ca and loss on ignition higher by factors of 4 (Euphrates), 5 (Tigris) or even 10-15 (Karun and Shatt-hatt al-Arab) for Ca and loss on ignition, and higher by factors of 2-3 for Mg and Sr. In Tigris, Euphrates, Karkheh and Karun sands, Cr is higher by an order of magnitude; Mo, Ni, Cu and As are also markedly higher.…”

Abstract: We present a detailed sediment-provenance study on the modern Euphrates-Tigris-Karun fluvial system and Mesopotamian foreland basin, one of the cradles of humanity. Our rich petrographic and heavy-mineral dataset, integrated by sand geochemistry and U-Pb age spectra of detrital zircons, highlights the several peculiarities of this large source-tosink sediment-routing system and widens the spectrum of compositions generally assumed as paradigmatic for orogenic settings. Comparison of classical static versus upgraded dynamic petrologic models enhance the power of provenance analysis, and allow us to derive a more refined conceptual model of reference and to verify the limitations of the approach. Sand derived from the Anatolia-Zagros orogen contains abundant lithic grains eroded from carbonates, cherts, mudrocks, arc volcanics, obducted ophiolites and ophiolitic mélanges representing the exposed shallow structural level of the orogen, with relative scarcity of quartz, Kfeldspar and mica. This quartz-poor petrographic signature, characterizing the undissected composite tectonic domain of the entire Anatolia-Iranian plateau, is markedly distinct from that of sand shed by more elevated and faster-eroding collision orogens such as the Himalaya. Arid climate in the region allows preservation of chemically unstable grains including carbonate rock fragments and locally even gypsum, and reduces transport capacity of fluvial systems, which dump most of their load in Mesopotamian marshlands upstream of the Arabian/Persian Gulf allochemical carbonate factory. Quartz-poor sediment from the AnatoliaZagros orogen mixes with quartz-rich recycled sands from Arabia along the western side of the foreland basin, and is traced all along the Gulf shores as far as the Rub' al-Khali sand sea up to 4000 km from Euphrates headwaters.Reviewer #1: This is an excellent review of an intriguing complex modern sediment source-to-sink system that has not been studied in a comprehensive manner prior to...
