南海北部新生代海陆变迁与不同盆地的沉积充填响应
The Cenozoic changes of seas and lands and sedimentary filling responses of different basins in northern South China Sea
摘要
Abstract
Multiple continental margin basins of different property and evolution were formed in the multi-cycle movement of the South China Sea since the Cenozoic.Based on the stratigraphic characteris-tics,seismic and drilling data of the basins,the analyses of relative sea level changes and sedimentary environment were conducted.And chronostratigraphic correlation method was used to discuss the changes of seas and lands in response to the structural evolution.Eventually the structure-sedimentary filling integrated patterns of continental margin rift basin,strike slip pull apart basin and continental rift basin in the north-ern South China Sea were established.The changes of seas and lands of the continental margin in the north-ern South China Sea was reconstructed to determine the scope of the sea water in the Cenozoic.The sea <br> level shows a rising trend through the whole Cenozoic,with continental river,coarse delta and lacustrine facies in Paleogene and delta and littoral-neritic sea facies mainly in Neogene.The transgression of sea wa-ter occurred later in continental rift basin (Beibuwan Basin,closer to land),resulting in a larger coarse delta filling thickness in Paleogene than that in the Neogene.However,the strike slip pull apart basin (Yinggehai basin,closer to sea) is characterized by fine-grained marine deposits in Neogene.And the continental margin basins show a relative sedimentary balance between the Paleogene and Neogene,re-spectively deltas and carbonate rock platform.Sedimentary filling of different basins is mainly controlled by tectonic movements and transgressive scale,thus their resource potentials are different.关键词
