Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical Monograph Series, Page 1-26., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Metasomatized lithospheric mantle for Mesozoic giant gold deposits in the North China craton [PDF]

open access: yes, 2020
The origin of giant lode gold deposits of Mesozoic age in the North China craton (NCC) is enigmatic because high-grade metamorphic ancient crust would be highly depleted in gold.

A Paradigm Shift: North China Craton's North Margin Orogen Is the Collisional Suture With the Columbia Supercontinent

open access: yesGeochemistry, Geophysics, Geosystems, 2023
In a new study, Wu, Wang, Zhou, Zhao, Haproff, et al. (2022, https://doi.org/10.1029/2022GC010662) present a comprehensive study of the North Margin Orogen of the North China Craton (NCC), showing that older accreted rocks in this belt preserve a record ...

Meso-Neoproterozoic tectono-thermal evolution in the northern margin of North China Craton: Constraints from zircon (U-Th)/He ages

open access: yesDizhi lixue xuebao, 2022
Due to the complicated tectonic and sedimentary history and the lack of effective paleo-thermal indicators, the Meso-Neoproterozoic thermal history of the Yanliao rift zone in the northern margin of the North China Craton is ambiguous, which causes the ...

Craton Destruction Induced by Drastic Drops in Lithospheric Mantle Viscosity

open access: yesEarth and Space Science, 2022
The disruption of the mantle roots of cratons is common after cratonization. Craton destruction, which is characterized by severe lithospheric thinning, extensive thrust and extensional deformation, basin filling, and intense thermal activities, is ...

Effect of rheological heterogeneities on the lithospheric deformation of the Tibetan Plateau and neighbouring regions

open access: yesFrontiers in Earth Science, 2023
The Tibetan Plateau, induced by the India-Eurasian collision, has the highest average altitude in the world. During its uplift vertically, the Tibetan Plateau has been considered to expand laterally.

Contrasted tectonic styles for the Paleoproterozoic evolution of the North China Craton. Evidence for a ~2.1 Ga thermal and tectonic event in the Fuping Massif [PDF]

open access: yes, 2008
International audienceStructural analysis along with 40Ar–39Ar and U–Pb datings in the Fuping massif provide new insight into the evolution of the eastern part of the Trans-North China Belt (North China Craton), from 2.7 Ga to 1.8 Ga.

Eoarchean to Paleoproterozoic Crustal Evolution in the North China Craton [PDF]

open access: yesGoldschmidt Abstracts, 2020
<p>The early evolution of continental crust, particularly its lower layer, during the first 2.0 billion years of Earth history remains enigmatic. Here, we present the first coupled in-situ U-Pb, Lu-Hf and O isotope data for the Precambrian zircons from fourteen deep-crustal xenoliths from five localities in the North China craton.

Chemical Significance and Chronology of Mesoproterozoic clastic rocks in Huainan Area

open access: yesChemical Engineering Transactions, 2018
After the 1.8Ga cracking event, the North China Craton entered the development stage of paraplatform, its southern margin, the Huainan area is in lack of accurate age data, so its stratigraphic sedimentation time limit has been controversial.
