Abstract

Abstract

The main elements of Core 191 are analyzed using the method of XRF in the northern South China Sea.The results show that the main element of the highest content is SiO₂, the next is CaCO₃, Al₂O₃ and CaO.In the vertical distribution the content of CaCO₃ is coincident with that of CaO, and the content of SiO₂ is similar to that of Al₂O₃, Fe₂O₃, K₂O and MgO.Combined with the dating of AMS(carbon-14), five geochemistry layers are divided, this is indicated that the changing of main elements and the content ratio of MgO to Al₂O₃ along the core have reflected the evolution of climate, sea level and terrigenous mater supply since oxygenisotope Stage 3 in the northern South China Sea.And the changing has good corre-spondence to short period global climate change such as Heinrich event, Dansgaerd-Oeschger gyration, Younger Dry as event and Pulleniatina obliquiloculata event, just little late to Greenland Island ice core because of regional response.Since oxygenisotope Stage 3, the deposited rate in the study area has dropped, not as the common result that the deposited rate in interglacial stage or warm period is higer than that in glacial stage or cold period in orther areas of the South China Sea.The reason is that rocks are easier to weathering and to eroding in the frequent climate oscillation of heat and cold or dryness and wetness in this stage.
