Late Ordovician gastropods from the Zhaolaoyu Formation in the southwestern margin of the North China Platform [PDF]

open access: yesEstonian Journal of Earth Sciences, 2023
The Ordos Basin is located in the western part of the North China Platform and is the second largest sedimentary basin in China; the basin has a huge thickness of the Early Palaeozoic marine deposits, especially the Ordovician ones.

Quantitative reconstruction of Early Cretaceous dune morphology in the Ordos paleo-desert and its paleoclimatic implications

open access: yesFrontiers in Earth Science, 2023
Deserts are among the most important terrestrial sedimentary environments and have existed in all periods throughout Earth’s history. In contrast to modern deserts, the ability to quantitatively evaluate the area and desertification degrees of ancient ...

Development or absence of conjugate fractures in low-permeability sandstones

open access: yesFrontiers in Earth Science, 2023
Natural fractures are ubiquitous in rocks. The Coulomb law of Mohr’s failure theory predicts that the angle between conjugate failure surfaces is a constant. In the Ordos Basin, observing the development of two groups of conjugate fractures in the field,
