New constraints on the pre-Permian continental crust growth of Central Asia (West Junggar, China) by U-Pb and Hf isotopic data from detrital zircon. [PDF]

open access: yes, 2012
International audienceIn-situ U-Pb geochronology of detrital zircons from various Palaeozoic sedimentary rocks of West Junggar accretionary complexes (Central Asia) suggests two distinct episodes of arc magmatism, and an evolution in three steps: i ...

Mesozoic–Cenozoic Thermochronology of the Tarim–Southern Tianshan System, NW China

open access: yesGeological Journal, EarlyView.
Tectonothermal history of the Tarim–Southern Tianshan system compared with the major tectonic events at far‐field plate margins. ABSTRACT The Tarim Basin, an oil‐bearing basin in northwest China, is tectonically and sedimentologically linked to the Southern Tianshan Orogenic Belt.

Forty years of captive breeding in Przewalski's horse: pedigree‐based insights into population growth, sex ratio, and inbreeding

open access: yesWildlife Biology, EarlyView.
Long‐term captive breeding programs play a critical role in the conservation and reintroduction of endangered species, yet they face persistent challenges related to demographic structure and genetic management. The Przewalski's horse Equus przewalskii, once extinct in the wild, represents a global model for conservation breeding supported by pedigree ...

Influence Analysis and Spectral Shape Correction of Nuclear Magnetic Logging in Ultra-Deep Oil and Gas Wells

open access: yesCejing jishu, 2023
The ultra-deep wells in Junggar basin are drilled with oil-based mud. The oil-based mud intruded into the formation affects the physical response characteristics of nuclear magnetic logging, and can not truly reflect the pore structure of the formation ...

Neogene uplift of the Tian Shan Mountains observed in the magnetic record of the Jingou River section (northwest China) [PDF]

open access: yes, 2009
The Tian Shan Mountains constitute central Asia's longest and highest mountain range. Understanding their Cenozoic uplift history thus bears on mountain building processes in general, and on how deformation has occurred under the influence of the India ...

Climate and Land‐Use Change May Reshape the Biogeography of Freshwater Crabs Across China

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
We employed ensemble species distribution models to investigate how climate and land‐use change will impact habitat suitability for two freshwater crab families (Potamidae and Sesarmidae) across China. Temperature emerged as the dominant driver, with cropland and urban land having strong, family‐specific effects on suitability. Future scenarios predict

Phylogenetics, Niche Evolution, and Distribution Dynamics of Isatis Species Under Climate Change

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
This study systematically elucidates the adaptive evolution of Isatis species from the perspective of life‐history strategies and niche evolution, highlights the increased extinction risk faced by wild relatives, and provides a critical scientific basis for the conservation and sustainable use of the germplasm resources of this genus.

From oblique accretion to transpression in the evolution of the Altaid collage: New insights from West Junggar, northwestern China [PDF]

open access: yes, 2012
International audienceAlong active margins, tectonic features that develop in response to plate convergence are strongly controlled by subduction zone geometry.

Mg isotope fractionation during microbial dolomite formation in the Khor Al‐Adaid sabkha, Qatar

open access: yesThe Depositional Record, Volume 12, Issue 2, April 2026.
Modern sabkha sediments from southern Qatar show ca. 1‰ Ca isotope fractionation between pore water, organic matter and dolomite, supporting microbial mediation. In contrast, minimal Mg isotope fractionation and inorganic‐like dolomite δ26Mg indicate that microbial influence is indirect, expressed through subtle pore water shifts driven by Mg ...
