| Abstract: | According to the synthetic multi-disciplinary study on the lake sediments from core RM of Zoige Basin, i.e. the deepest wholly-collected
core in Tibetan Plateau, the palaeoclimate and palaeoenvironment for the basin in the past 0.9 Ma have been reconstructed.
The analytical results suggest that there distinctively exist 3 accelerated uplifting periods for the east Plateau in the
past 0.9 Ma, i.e. 800, 360 and 160 kaB.P., with the study on the sedimentary characteristics, the texture of sedimentary cycles
and variations of depositional rates, in conjunction with the environment features of cold/warm to dry/wet combination. The
paper also probes into the environmental effect under the 3 accelerated tectonic-upliftings on the background of global change. |
