Late Mesozoic Intracontinental Deformation in the Northern Margin of the North China Craton: A Case Study From the Shangyi Basin, Northwestern Hebei Province, China

Frontiers in Earth Science, 2021
During the late Mesozoic, the East Asian continent underwent a complex tectonic history due to multiple episodes of plate convergence. How the crust responds to the multiple plate convergence in the North China Craton (NCC) remains unclear.

Quantitative Provenance Analysis of the Yangtze and Yellow River Sediments Through Detrital Zircon U‐Pb Geochronology Using an XGBoost Machine Learning Algorithm

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract Over the past two decades, a large number of zircon U‐Pb ages from the Yangtze and Yellow River Basins have been published, yet distinguishing the sources of sediment between these regions remains challenging. Issues related to sampling, analytical methods, and biases complicate the interpretation of detrital zircon geochronology.

Stable Isotope Characteristics and Recharge Mechanisms of River, Lake and Groundwater by Precipitation in the Hulun Lake Basin

Hydrological Processes, Volume 39, Issue 6, June 2025.
Filling the gap in refined research on multimedia hydrological processes during wet seasons in a typical semi‐arid lake basin. The characteristics of δD and δ18O values of the precipitation, river water, lake water and groundwater and their relationships were elaborated, and the recharge rates were calculated among them by using the endmember element ...

Research on the differential tectonic-thermal evolution of Longmaxi shale in the southern Sichuan Basin [PDF]

, 2023
The southern Sichuan Basin in China holds abundant shale gas resources; however, the shale gas bearing property shows great differences due to the multiple stages of tectonic transformation.

Geological reassessment of syn‐rift extensional sequences in the Shine Usny Tolgod and Dzun Shakhai fossil localities, Eastern Gobi Basin, Mongolia

Sedimentology, Volume 72, Issue 4, Page 1275-1315, June 2025.
ABSTRACT Sedimentary infill patterns in the Eastern Gobi Basin of southern Mongolia record a complex, polyphased history. Asynchronous timing and intensities of extensional tectonism during the Early Cretaceous fragmented the Eastern Gobi Basin into a series of sub‐basins within an extensional rift (horst‐graben) setting, which likely infilled ...

A Late Paleozoic Hydrothermal Gold Mineralization Event in the Northern Margin of the North China Craton: Evidence of In Situ Apatite U‐Pb Dating and Hg Isotope Tracing of the Giant Hadamengou Gold Deposit

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.
Abstract The northern margin of the North China Craton (NCC) hosts large numbers of hydrothermal gold deposits, with mineralization ages ranging from the Paleozoic to Mesozoic eras. The genesis of these deposits has been primarily ascribed to magmatic‐hydrothermal or crustal‐metamorphic fluid models. The Hadamengou gold deposit (>170 t Au), the largest
