Magnetostratigraphy and paleoclimatic interpretation of a continuous 7.2 Ma Late Cenozoic Eolian sediments from the Chinese Loess Plateau
TLDR
In this paper, an almost 300m thick eolian sequence of Late Cenozoic sediments, which includes 162.5m of Quaternary loess-paleosols and 126m of Late Tertiary eolians Red Clay from the central part of the Chinese Loess Plateau, was investigated to determine the magnetostratigraphy.Abstract:
An almost 300m thick eolian sequence of Late Cenozoic sediments, which includes 162.5m of Quaternary loess-paleosols and 126m of Late Tertiary eolian Red Clay from the central part of the Chinese Loess Plateau, was investigated to determine the magnetostratigraphy. The results show that eolian dust accumulation, and by inference the related East Asia paleomonsoon, had begun by 7.2Ma. As paleomonsoon are largely controlled by the Tibetan Plateau, this implies that the Plateau had reached some critical elevation by 7.2Ma. The section also documents a rapid increase in eolian dust accumulation in the Late Cenozoic at 3.2Ma that is probably due to the influence of global ice volume on the East Asian monsoon.read more

Onset of Asian desertification by 22 Myr ago inferred from loess deposits in China
Zhengtang Guo,William F. Ruddiman,Qingzhen Hao,Huilan Wu,Yansong Qiao,Rixiang Zhu,Shuzhen Peng,Jia Wei,B. Y. Yuan,Tungsheng Liu +9 more
TL;DR: This new evidence indicates that large source areas of aeolian dust and energetic winter monsoon winds to transport the material must have existed in the interior of Asia by the early Miocene epoch, at least 14 million years earlier than previously thought.

The history and variability of the East Asian paleomonsoon climate
TL;DR: The history of the East Asian monsoon is an alternation between dominance by the dry-cold winter and warm-humid summer monsoons as mentioned in this paper, and high-resolution eolian sequences preserved in the Chinese Loess Plateau reveal evidence indicating that the pulsed uplift of the Tibetan Plateau at about 3.4 and 7.2 Ma may have played an important role in inducing climate change.

TL;DR: In this paper, the spatial and temporal distribution of summer monsoon precipitation during the Holocene has been reconstructed on the basis of geological data, including lake levels, pollen profiles, and loess/paleosol records.

How old is the Asian monsoon system?—Palaeobotanical records from China
TL;DR: In this paper, the authors present the results of a compilation of palaeobotanical and lithological data from 125 sites over China, that has revealed two completely different patterns of climate zones: the Palaeogene pattern with a broad belt of aridity stretched across China from west to east, and the Neogene patterns with the arid zone restricted to northwest of China which has persisted until today.

Evolution and variability of the Asian monsoon system: state of the art and outstanding issues.

TL;DR: The Asian monsoon is comprised of the Indian and East Asian subsystems, and the extent to which they interact with other climate phenomena (e.g., ENSO) are current topics of modern and paleoclimate research.

Revised calibration of the geomagnetic polarity timescale for the Late Cretaceous and Cenozoic
Steven C. Cande,Dennis V. Kent +1 more
TL;DR: An adjusted geomagnetic reversal chronology for the Late Cretaceous and Cenozoic is presented that is consistent with astrochronology in the Pleistocene and Pliocene and with a new timescale for the Mesozoic.

Forcing of late Cenozoic northern hemisphere climate by plateau uplift in southern Asia and the American west
TL;DR: In this article, the General Circulation Model sensitivity tests were run to isolate the unique effects of plateau uplift on climate, and the experiments simulated significant climatic changes in many places, some far from the uplifted regions.

TL;DR: In this paper, a general-circulation model was used to estimate the sensitivity of the Indian monsoon to changes in orbital parameters, the orography of Tibet-Himalaya, atmospheric C02 concentration and the extent of glacialage surface boundary conditions.
