| Outline of Final Research Achievements |
This research show that the long-period Milankovitch cycle paced global chemical weathering and carbon cycle through climate change during the Mesozoic on the basis of the geologic survey and chemical analysis of deep-sea and continental sequences with numerical modelling. We propose that Mega-monsoon over Supercontinent Pangea could have amplified the astronomical forcing. Our research provide new insights into the Earth system response to astronomical forcing during the Mesozoic greenhouse world.
