Evolution of Asian monsoons and phased uplift of the Himalaya–Tibetan plateau since Late Miocene times
TLDR
The results of a numerical climate-model experiment support the argument that the stages in evolution of Asian monsoons are linked to phases of Himalaya–Tibetan plateau uplift and to Northern Hemisphere glaciation.Abstract:
The climates of Asia are affected significantly by the extent and height of the Himalayan mountains and the Tibetan plateau1,2,3,4 Uplift of this region began about 50 Myr ago, and further significant increases in altitude of the Tibetan plateau are thought to have occurred about 10–8 Myr ago4,5, or more recently However, the climatic consequences of this uplift remain unclear Here we use records of aeolian sediments from China6,7 and marine sediments from the Indian8,9,10 and North Pacific oceans11 to identify three stages of evolution of Asian climates: first, enhanced aridity in the Asian interior and onset of the Indian and east Asian monsoons, about 9–8 Myr ago; next, continued intensification of the east Asian summer and winter monsoons, together with increased dust transport to the North Pacific Ocean11, about 36–26 Myr ago; and last, increased variability and possible weakening of the Indian and east Asian summer monsoons and continued strengthening of the east Asian winter monsoon since about 26 Myr ago The results of a numerical climate-model experiment, using idealized stepwise increases of mountain–plateau elevation, support the argument that the stages in evolution of Asian monsoons are linked to phases of Himalaya–Tibetan plateau uplift and to Northern Hemisphere glaciationread more

Abrupt shifts in the Indian monsoon during the Pliocene marked by high-resolution terrestrial records from the Yuanmou Basin in southwest China
TL;DR: A 650m-thick sequence of fluvio-lacustrine sediments from the Yuanmou Basin in southwest China was analyzed at 20-cm intervals for grain-size distribution to provide a high-resolution terrestrial record of Indian summer monsoon variations during the Pliocene.

Tectonic uplift-influenced monsoonal changes promoted hominin occupation of the Luonan Basin: Insights from a loess-paleosol sequence, eastern Qinling Mountains, central China
Qian Fang,Hanlie Hong,Lulu Zhao,Harald Furnes,Huayu Lu,Wen Han,Yao Liu,Zhuoyue Jia,Chaowen Wang,Ke Yin,Thomas J. Algeo,Thomas J. Algeo +11 more
TL;DR: In this article, the authors investigated a well-preserved and continuous Quaternary loess-paleosol sequence (Shangbaichuan) from the Luonan Basin, using a variety of weathering indices including major and trace element ratios, clay mineralogy, and Fe-oxide mineralogy.

A late Miocene–Early Pliocene biogenic silica crash in the Andaman Sea and Bay of Bengal
TL;DR: In this paper, the mass accumulation rate of biogenic opal during the past ∼9.4 million years was reconstructed using continental margin sediment cores from the Andaman Sea (Site NGHP-01-17A) and the northern Bay of Bengal (site NGHP -01-19) during the 2006 Indian National Gas Hydrate Program (NGHP) Expedition-01.

Climate, cryosphere and carbon cycle controls on Southeast Atlantic orbital-scale carbonate deposition since the Oligocene (30–0 Ma)

TL;DR: In this article, the authors identify three phases with distinctly different orbital controls on Southeast Atlantic CaCO3 deposition, corresponding to major developments in climate, the cryosphere and/or the carbon cycle.

Aeolian n-alkane isotopic evidence from North Pacific for a Late Miocene decline of C4 plant in the arid Asian interior
TL;DR: In this article, higher plant leaf wax n-alkanes from ODP Site 1208 and Site 886 in the North Pacific since the middle Miocene were analyzed to explore long-term changes in vegetation and climate in the source region.

Global vegetation change through the Miocene/Pliocene boundary

TL;DR: For example, this paper found that between 8 and 6 million years ago, there was a global increase in the biomass of plants using C4 photosynthesis as indicated by changes in the carbon isotope ratios of fossil tooth enamel in Asia, Africa, North America and South America.

Mantle dynamics, uplift of the Tibetan Plateau, and the Indian Monsoon
TL;DR: For example, Hou et al. as mentioned in this paper show that a small increase in the mean elevation of the Tibetan Plateau of 1000 m or more in a few million years is required by abrupt tectonic and environmental changes in Asia and the Indian Ocean.

Surface Deformation and Lower Crustal Flow in Eastern Tibet
Leigh H. Royden,B. Clark Burchfiel,Robert W. King,Erchie Wang,Zhiliang Chen,Feng Shen,Y. Liu +6 more
TL;DR: This model predicts east-west extension on the high plateau without convective removal of Tibetan lithosphere and without eastward movement of the crust east of the plateau.

Correlation between climate events in the North Atlantic and China during the last glaciation
TL;DR: The authors examined grain-size data from Chinese loess and intercalated accretionary palaeosols of last-glacial age for evidence of similar climate signals remote from the North Atlantic region.

Finite strain calculations of continental deformation .2. comparison with the india-asia collision zone
TL;DR: In this article, a thin viscous sheet model for deformation of continental lithosphere subjected to an indenting boundary condition yield distributions of crustal thickness, of stress and strain rate, and of latitudinal displacements that may be compared with observations in the India-Asia collision zone.
