Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program) 184 https://doi.org/10.2973/odp.proc.sr.184.201.2003 1-25 Pliocene core intervals from Ocean Drilling Program Site 1143 located in the southern part of the South China Sea were measured for their major and minor element composition at ~2-k.y. resolution. Changes in sediment composition parallel glacial-interglacial changes as indicated by the corresponding oxygen isotope record of benthic foraminifers. Carbonate contents are lower during glacial stages and higher during interglacial stages. This is attributed to dilution by a higher contribution of terrigenous detrital matter during glacial intervals and to enhanced biological productivity during interglacials as indicated by enrichments in barium. The terrigenous detrital matter fraction shows small but distinct changes in composition. These variations may be explained by multiple processes, including changes in provenance and weathering caused by monsoonal climate variability and sea level fluctuations. Gradual or long-term changes in sediment composition also occur during the investigated interval. There is a shift toward lower TiO2 (carbonate-free basis; cfb) values at around 2.9 Ma and an increase in Al2O3 (cfb) variations at around 2.55 Ma. These changes can be explained in both cases by an increasing contribution from the Mekong River, delivering material with low TiO2 (cfb)/Al2O3 (cfb) ratios, followed by a gradual increase in weathering, causing higher Al2O3 (cfb) (probably reflecting kaolinite) contents. Both may be the result of an enhanced summer monsoon. The manganese and phosphate geochemistry of Site 1143 sediments seem to be strongly dominated by biological productivity and a high burial flux of carbonate, which acts as an adsorbing agent and/or substrate. During strong interglacials and corresponding times of enhanced productivity, Mn may be remobilized from continental margin sediments deposited within an oxygen minimum zone and subsequently exported into the pelagic region, where it oxidizes and settles to form Mn-enriched layers in the sediment. 113.285133333333 113.285133333333 9.36193333333333 9.36193333333333 113.285133333333 9.36193333333333 1999-03-03T00:00:00 1999-03-10T00:00:00 99.5 136.46 ODP Ocean Drilling Program https://www-odp.tamu.edu:443/ Ocean Drilling Program, Texas A&M University ODP http://www-odp.tamu.edu/ https://ror.org/01f5ytq51 184-1143 9.3619333333333 113.28513333333 South China Sea http://en.wikipedia.org/wiki/South_China_Sea -2772.3 1999-03-03T00:00:00 1999-03-10T00:00:00 Leg184 Leg184 1999-03-03T00:00:00 1999-03-03 1999-04-10T00:00:00 1999-04-10 Joides Resolution https://www-odp.tamu.edu:443/resolutn.html Wang, Pinxian Wang, Pinxian Prell, Warren L Prell, Warren L doi:10.2973/odp.proc.ir.184.2000 Joides Resolution https://www-odp.tamu.edu:443/resolutn.html Composite Core COMPCORE 1158.2 m 1101.8 m 126 cores; 1158.2 m cored; 0 m drilled; 95.1% recovery 6714 CC-BY-3.0 Creative Commons Attribution 3.0 Unported https://creativecommons.org/licenses/by/3.0/ Sediment depth is given in mcd.
