Abstract Combined analyses of deep tow magnetic anomalies and International Ocean Discovery Program Expedition 349 cores show that initial seafloor spreading started around 33 Ma in the northeastern South China Sea (SCS), but varied slightly by 1–2 Myr along northern continent‐ocean boundary (COB). A southward ridge jump ∼20 km occurred 23.6 East Subbasin; this timing also was coeval to onset Southwest Subbasin, which propagated for about 400 southwestward from ∼23.6 ∼21.5 Ma. The terminal...
Abstract Coring/logging data and physical property measurements from International Ocean Discovery Program Expedition 349 are integrated with, correlated to, reflection seismic to map sequence boundaries facies of the central basin neighboring regions South China Sea. First‐order interpreted, which Oligocene/Miocene, middle Miocene/late Miocene, Miocene/Pliocene, Pliocene/Pleistocene boundaries. A characteristic early Pleistocene strong reflector is also identified, marks top extensive...
Abstract. In this study, we use inorganic (metal) and organic (bulk molecular) markers in sediment samples of the south-eastern Brazilian margin to investigate response geochemical fingerprints complex hydrodynamic processes present area. Results indicate potential export terrigenous siliciclastic constituents upper slope, even an area with limited fluvial supply.Metal contents especially ln(Ti ∕ Al) ln(Fe K) ratios make it possible recognise extension shelf sediments toward slope....
The aim of this work was to generate an inventory the data on radiocarbon datings obtained from sediments São Paulo Bight (southern Brazilian upper margin) and analyze in terms Late Quaternary sedimentary processes sedimentation rates. A total 238 materials collected using differents ampling procedures considered for work. rates varied less than 2 68 cm.kyr-1. highest rate values were found a low-energy (ría type) coastal system as well upwelling zones Santa Catarina Cabo Frio. lowest outer...
Changes in the Brazilian continental margins oceanic productivity and circulation over last 27,000 years were reconstructed based on sedimentological microfaunal analyses. Our results suggest that paleoproductivity supply of terrigenous sediments to margin higher during Last Glacial Maximum (LGM) than Holocene. These changes may have been primarily influenced by significant sea level fluctuations occurred since late Pleistocene. During LGM, lower level, sea-surface paleotemperatures result...
Abstract The southern Brazilian shelf (extending from 34°S to 22°S) is discussed with special emphasis on its Holocene sedimentary evolution. onset of the Rio de la Plata plume influence inner during Late and reworking seafloor sediments by Brazil Current in outer upper slope are key elements. High-resolution records have revealed palaeoceanographic changes shelf, highlighting importance this sector comprehension palaeoclimate South America, especially regarding oscillations wind regime...
