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

Chloroplast phylogenomics and character evolution of eastern Asian Astragalus (Leguminosae): Tackling the phylogenetic structure of the largest genus of flowering plants in Asia
TL;DR: It is hypothesize that the uplifts of the QTP, which contributed to aridification in eastern Asia and the adjacent regions, may have accelerated the rapid speciation of Astragalus, especially the xerophilous groups (i.e. the medifixed hair groups).

TL;DR: In this article, the Tierekesazi section of the foreland region of south West Tian Shan has been investigated for sedimentology and magnetostratigraphy in order to understand the intracontinental orogeny in the context of Indian-Eurasian convergence.

Zhanguo Liu,Chao Zhu,Senming Li,Jianqin Xue,Qingshun Gong,Yanqing Wang,Peng Wang,Zhiyuan Xia,Guangyong Song +8 more
TL;DR: Li et al. as discussed by the authors evaluated four potential fields of tight oil exploration in western Qaidam Basin from comprehensive analysis of geological conditions such as sedimentary environments, source rock evaluations, reservoir characteristics, and source-reservoir relationships.

Geochemical evidence on the source regions of Tibetan Plateau dusts during non-monsoon period in 2008/09
TL;DR: In this article, the authors analyzed the rare earth element compositions of snow-pit dust in the Tibetan Plateau during the non-monsoon period in 2008/2009 and found that the enrichment factors of all the elements of snowpit dust are identical to those of the upper continental crust.

Long-term sky islands generate highly divergent lineages of a narrowly distributed stream salamander (Pachyhynobius shangchengensis) in mid-latitude mountains of East Asia.

TL;DR: The results suggest that the niche conservatism of P. shangchengensis and sky island effects may have led to long-term isolation between populations, which has led to the accumulation of genetic diversity and has promoted genetic divergence.

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.

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.
