Vegetation evolution and its response to climatic change during 3.15-0.67 Ma in deep-sea pollen record from northern South China Sea
In order to study vegetation evolution and environmental change during 3.15-0.67 Ma, a total of 608 pollen samples with an average time resolution of 4 ka has been analyzed from ODP Site 1145 (water depth 3175 m), northern South China Sea. The deep-sea sediments (213.62-91.9 m) cover from 3.15 to 0....
