“…These measurements must be performed in concert with provenance work to establish whether any of the chemical changes could be driven by changes in source composition or drainage capture rather than weathering intensity. Bulk sediment and single-grain provenance methods, including heavy mineral studies, U-Pb dating of detrital zircons, Ar-Ar dating of detrital mica grains, Nd isotopes, and apatite fission track represent some of the methods known to be effective in this drainage system that will allow tracking of changing patterns of erosion caused by waxing and waning of the monsoon (Clift et al, 2004;Garzanti et al, 2005;Alizai et al, 2011).…”

The Indian (southwest) summer monsoon is one of the most intense climatic phenomena on Earth. Its long-term development has been linked to the growth of high topography in South and Central Asia. The Indian continental margin, adjoining the Arabian Sea, offers a unique opportunity to investigate tectonic-climatic interactions and the net impact of these processes on weathering and erosion of the western Himalaya. During International Ocean Discovery Program Expedition 355, two sites (U1456 and U1457) were drilled in Laxmi Basin in the eastern Arabian Sea to document the coevolution of mountain building, weathering, erosion, and climate over a range of timescales. In addition, recovering basement from the eastern Arabian Sea provides constraints on the early rifting history of the western continental margin of India with special emphasis on continental breakup between India and the Seychelles and its relationship to the plume-related volcanism of the Deccan Plateau.Drilling and coring operations during Expedition 355 recovered sediment from Sites U1456 and U1457 in the Laxmi Basin, penetrating 1109.4 and 1108.6 m below seafloor (mbsf ), respectively. Drilling reached sediment dated to 13.5-17.7 Ma (late early to early middle Miocene) at Site U1456, although with a large hiatus between the lowermost sediment and overlying deposits dated to <10.9 Ma. At Site U1457, a much longer hiatus occurs near the base of the cored section, spanning from 10.9 to ~62 Ma. At both sites, hiatuses span ~8.2-9.2 and ~3.6-5.6 Ma, with a possible condensed section spanning ~2.0-2.6 Ma, although the total duration for each hiatus is slightly different between the two sites.A major submarine fan draining the western Himalaya and Karakoram must have been supplying sediment to the eastern Arabian Sea since at least ~17 Ma. Sand mineral assemblages indicate that the Greater Himalayan Crystalline Sequence was fully exposed to the surface by this time. Most of the recovered sediment appears to be derived from the Indus River and includes minerals that are unique to the Indus Suture Zone, in particular glaucophane and hypersthene, most likely originating from the structural base of the Kohistan arc. Pliocene sandy intervals at Site U1456 were deposited in lower fan "sheet lobe" settings, with intervals of basin plain turbidites separated by hemipelagic muddy sections deposited during the Miocene. Site U1457 is more distal in facies, reflecting its more marginal setting. No major active lobe appears to have affected the Laxmi Basin since the Middle Pleistocene (~1.2 Ma).We succeeded in recovering sections spanning the 8 Ma climatic transition, when monsoon intensity is believed to have changed strongly, although the nature of this change awaits postcruise analysis. We also recovered sediment from a large mass transport deposit measuring ~330 and ~190 m thick at Sites U1456 and U1457, respectively. This section includes an upper sequence of slump-folded muddy and silty rocks, as well as underlying calcarenites and limestone breccias, to...

“…So the plateau always supplies detritus from inside to outside (Bodet and Schärer, 2000;Campbell et al, 2005;Allen et al, 2008;Liang et al, 2008;Hoang et al, 2009;Alizai et al, 2011;Zhang et al, 2012a), but the central plateau itself can only receive the local detritus (Decelles et al, 2007). The detritus from the CAOB and NQO was transported to the Ordos, Ningwu, and Jiyuan basins and the basins in the eastern NCC Meng et al, 2010;Li et al, 2013) in the Jurassic, which argues against the proposal that there was an elevated plateau in the eastern NCC during Jurassic (Ren et al, 1990;Dong et al, 2000;Zhang et al, 2001Zhang et al, , 2007aZhang et al, , 2008Zhang et al, , 2009a.…”

“…et al, 2012). A typical example is that the modern Tibetan Plateau always supply detritus from inside to outside (Bodet and Schärer, 2000;Campbell et al, 2005;Allen et al, 2008;Liang et al, 2008;Hoang et al, 2009;Alizai et al, 2011), but the central plateau itself can only receive locally derived detritus (Decelles et al, 2007). A low elevation of the eastern NCC during the Jurassic is consistent with a warm and humid paleoclimate at that time (Wang, 1985;Scotese, 2002), as suggested by development of coal and dinosaur fossils in the eastern NCC (Rees et al, 2004).…”

“…All these rivers are flowing outward from the central Tibetan Plateau. An obvious rule is that the basins located in the downstream of these rivers can receive detritus from the upstream, even from the central Tibetan Plateau (Bodet and Schärer, 2000;Campbell et al, 2005;Allen et al, 2008;Liang et al, 2008;Hoang et al, 2009;Alizai et al, 2011). However, the basins in the central Tibetan Plateau cannot receive detritus derived outside of the Plateau, with detritus totally being derived from within the plateau (Decelles et al, 2007).…”
