It is debated as to whether the modern-like East Asian monsoon formed during late Oligocene–early Miocene or Eocene. To resolve this dispute requires a comprehensive and updated synthesis of available geological records reliable modelling study. Here, we investigate Cenozoic climate patterns over Asia by compiling conducting for key periods based on our improved paleogeographies. Geological suggest that zonal (semi-)arid pattern was dominant tectonic timescales most Paleogene in...
Abstract Various modeling studies have examined the climatic effects of either Central American Seaway or Indonesian seaway. The co‐existence these two tropical seaways may a greater influence than existence single Although dual seaway situation is closer to that reconstructed during Miocene/Pliocene, relevant remain scarce. Here, we investigate co‐effects changes on Pacific circulation through set sensitivity experiments. Our results show combined shallow opening can generate an active...
Abstract Inconsistencies in the Eocene climates of East Asia have been revealed both geological studies and simulations. Several earlier reconstructions showed an arid zonal band mid‐latitude China, but others a humid climate same region. Moreover, previous modeling demonstrated that models can simulate scenarios China. Therefore, it is essential to investigate cause this model spread. We conducted series experiments using Norwegian Earth System Model 1‐F examined impact mountains Southern...
Abstract Constraining the uplift of northeastern Tibetan Plateau (NETP) is critical for growth models plateau and tectonic‐climatic interactions during Cenozoic. The sequence early Eocene (53 Ma)‐early Miocene (16 Ma) clastic sediments deposited in Xining Basin provides insights into NETP. We used Nd‐Pb isotopic composition Cenozoic to trace sediment sources hence infer Provenance analysis indicates that Qilian Shan was possibly source area before ~50 Ma; West Qinling became main ~50–39...
Abstract During the Miocene, major global cooling occurred during two intervals: middle Miocene (∼14–13 Ma) and late (∼7‐6 Ma). The Antarctic Ice Sheet expanded substantially at ∼14–13 Ma, glaciation in Northern Hemisphere was initiated ∼7–6 Ma. Although causes of these events remain unclear, paleoclimate modeling provides an important approach for investigating mechanisms. However, relies on paleogeographic boundary conditions, many uncertainties regarding land–sea distribution, topography,...
Abstract The Eocene was the initial stage of Cenozoic global climatic transition from greenhouse to icehouse conditions. Our understanding climate is based mainly on marine records, and comparison terrestrial records has revealed inconsistencies. Thus, there a need for more continuous, high‐resolution sedimentary land. Xining Basin in northeastern Tibetan Plateau contains sequence well‐exposed complete strata. Extending previous research, we have conducted new lithostratigraphic...
A real spatial continuous modeling of climate and carbon cycle is developed, tested for early Cenozoic from 60 Ma to 40 Ma.
Paleoclimate reconstruction and aeolian deposits in China indicate a major environmental reorganization – the formation of nonzonal monsoon-dominated climate pattern East Asia occurred late Oligocene early Miocene. In contrast, zonal planetary-wind-dominated occupied Paleocene Eocene. However, many recent studies has questioned this classical paradigm. Here, we highlight importance orbital-scale oscillations understanding reassessing Using sequence halite mudstone from Jianhan Basin...
<p>The early Eocene is a warm period with very high atmospheric CO<sub>2</sub> levels, which receives many interests from climate modelling aspects. To simulate the paleoclimate, realistic reconstruction for land-sea distribution, paleotopography and paleobathymetry fundamental step. Here, we present global paleogeographic reconstructions (~55 Ma), based on integrated data set, Plate-tectonic software (GPlates) Geographic Information System (ArcGIS)....
