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

Denudational response to surface uplift in east Tibet: Evidence from apatite fission-track thermochronology
TL;DR: In this article, the authors show that most of the denudation in the east Tibetan Plateau interior has occurred in major river valleys, where incision in the major rivers of the Longman Shan occurred simultaneously and has kept pace with surface uplift that began in the middle-late Miocene (12 Ma).

Stable isotopic variations in modern herbivore tooth enamel, plants and water on the Tibetan Plateau: Implications for paleoclimate and paleoelevation reconstructions
Yang Wang,Elizabeth Kromhout,Chunfu Zhang,Yingfeng Xu,William C. Parker,Tao Deng,Zhuding Qiu +6 more
TL;DR: In this article, the carbon and oxygen isotope analyses of fossil teeth and other authigenic minerals have been used to reconstruct the paleoenvironment and paleoelevation of the Tibetan Plateau.

Molecular phylogeny of the specialized schizothoracine fishes (Teleostei: Cyprinidae), with their implications for the uplift of the Qinghai-Tibetan Plateau
TL;DR: Molecular clock data do not support the hypothesis that the Qinghai-Tibetan Plateau uplifted to near present or even higher elevations during the Oligocene or Miocene, and neither in agreement with the view that the plateau uplifting reached only to an altitude of 2000 m during the late Pliocene (about 2.6 MaBP).

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.
