Mineralogical and geochemical investigations on South China Sea sediments journal article Palaeogeography, Palaeoclimatology, Palaeoecology 228(3-4) https://doi.org/10.1016/j.palaeo.2005.06.005 260-277 A coupled approach based on clay mineral assemblages and isotopic data (Sr and Nd) of sediment from Ocean Drilling Program (ODP) Site 1145 has been used to trace the sources of sediment feeding the northern part of the South China Sea, and to investigate the evolution of East Asian monsoon intensity over the last 450 ky. Clay mineral assemblages are dominated by illite and smectite, with lesser abundance of chlorite and kaolinite. 87Sr / 86Sr and epsilonNd(0) isotopic data, combined with the smectite / (illite+chlorite) ratio, indicate that the Pearl River is the main contributor for detrital material to the northern margin of the SCS, with variable continental input of volcanic material derived from the erosion of the Luzon Arc. These inputs follow the low-latitude solar insolation with a 23 ky periodicity, as recorded by a periodic change of the clay mineralogy. For the first time, this study presents a SCS deep-sea sediment high-resolution record of climatic changes in the last 450 ky, showing that smectite / (illite+chlorite) variations are mainly related to changes in the East Asian summer monsoon intensity. Because the mineralogical record is independent of other external forcing phenomena such as global glacial/interglacial oscillations, the smectite / (illite+chlorite) ratio has been used here as a proxy to reconstruct past changes of the South-East Asian summer monsoon intensity. 117.630966666666 117.630966666666 19.5840166666666 19.5840166666666 117.630966666666 19.5840166666666 1999-03-18T00:00:00 1999-03-21T00:00:00 0.88 70.63 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 184-1145 19.584016666667 117.63096666667 South China Sea http://en.wikipedia.org/wiki/South_China_Sea -3175.5 1999-03-18T00:00:00 1999-03-21T00:00:00 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 598.1 m 554.7 m 65 cores; 598.1 m cored; 0 m drilled; 92.7% recovery 368 CC-BY-3.0 Creative Commons Attribution 3.0 Unported https://creativecommons.org/licenses/by/3.0/ DEPTH, sediment/rock Depth sed m depth http://purl.obolibrary.org/obo/PATO_0001595 sediment http://purl.obolibrary.org/obo/ENVO_00002007 rock Length L http://dbpedia.org/resource/Length Depth sed [m] AGE Age ka BP http://en.wikipedia.org/wiki/Kyr age http://purl.obolibrary.org/obo/PATO_0000011 Time T http://dbpedia.org/resource/Time Age [ka BP] Sample code/label Sample label DSDP/ODP/IODP sample designation hdl:10013/epic.27914.d001 Boulay Sebastien Sample label Strontium Sr mg/kg strontium Mass spectrometer Finnigan MAT 262 Chromatographs & spectrometers mass spectrometers http://vocab.nerc.ac.uk/collection/L05/current/LAB16/ Boulay Sebastien Sr [mg/kg] Rubidium Rb mg/kg rubidium Mass spectrometer Finnigan MAT 262 Chromatographs & spectrometers mass spectrometers http://vocab.nerc.ac.uk/collection/L05/current/LAB16/ Boulay Sebastien Rb [mg/kg] Neodymium Nd mg/kg neodymium Nd Mass spectrometer Finnigan MAT 262 Chromatographs & spectrometers mass spectrometers http://vocab.nerc.ac.uk/collection/L05/current/LAB16/ Boulay Sebastien Nd [mg/kg] Rubidium/Strontium ratio Rb/Sr rubidium strontium ratio Mass spectrometer Finnigan MAT 262 Chromatographs & spectrometers mass spectrometers http://vocab.nerc.ac.uk/collection/L05/current/LAB16/ Boulay Sebastien Rb/Sr Strontium-87/Strontium-86 ratio 87Sr/86Sr strontium-87 87Sr strontium-86 86Sr https://en.wikipedia.org/wiki/Isotopes_of_strontium ratio Mass spectrometer Finnigan MAT 262 Chromatographs & spectrometers mass spectrometers http://vocab.nerc.ac.uk/collection/L05/current/LAB16/ Boulay Sebastien 87Sr/86Sr Strontium-87/Strontium-86 ratio, error 87Sr/86Sr e ± strontium-87 87Sr strontium-86 86Sr https://en.wikipedia.org/wiki/Isotopes_of_strontium Mass spectrometer Finnigan MAT 262 Chromatographs & spectrometers mass spectrometers http://vocab.nerc.ac.uk/collection/L05/current/LAB16/ Boulay Sebastien 2 sigma 87Sr/86Sr e [±] Neodymium-143/Neodymium-144 ratio 143Nd/144Nd ratio Mass spectrometer Finnigan MAT 262 Chromatographs & spectrometers mass spectrometers http://vocab.nerc.ac.uk/collection/L05/current/LAB16/ Boulay Sebastien 143Nd/144Nd Neodymium-143/Neodymium-144 ratio, error 143Nd/144Nd e ± neodymium-143 143Nd neodymium-144 144Nd Mass spectrometer Finnigan MAT 262 Chromatographs & spectrometers mass spectrometers http://vocab.nerc.ac.uk/collection/L05/current/LAB16/ Boulay Sebastien 2 sigma 143Nd/144Nd e [±] ε-Neodymium (0) ε-Nd(0) Mass spectrometer Finnigan MAT 262 Chromatographs & spectrometers mass spectrometers http://vocab.nerc.ac.uk/collection/L05/current/LAB16/ Boulay Sebastien ε-Nd(0) supplement citable author23291 author26008 author32702 author32703 author32704 basis5 campaign21655 campaign3383780 event2075122 geocode1 geocode1599 geocode1600 geocode1601 geocode2205 geocode8128 inst34 journal12485 license101 method10895 method5059 method795 param1666 param18576 param2270 param28423 param6099 param678 param687 param6990 param790 param81 pi32702 project3 ref28907 term1073131 term1073135 term20656 term2299515 term2663825 term38263 term40663 term40739 term41045 term41056 term41204 term41205 term42031 term43863 term43975 term44325 term68027
