Effectiveness assessment and spatial distribution characteristics of helium source rocks in the Shixi Block along the eastern margin of the Ordos Basin

Meitian dizhi yu kantan
BackgroundHelium gas serves as a significant rare strategic resource. In China, helium resources are relatively scarce and dependent heavily on imports. Therefore, there is a pressing need for the exploration and exploitation of helium resources.

Microstructure and heterogeneity of coal-bearing organic shale in the southeast Ordos Basin, China: Implications for shale gas storage

Frontiers in Earth Science, 2022
In recent years, the eastern margin of Ordos Basin has attracted much attention as a key base for unconventional natural gas exploration. The pore-fracture structure is an important physical property of shale and provides places and channels for methane ...

Lithofacies paleogeography of the Ordovician Kelimoli-Lashizhong formations along the western margin of the Ordos Basin

Meitian dizhi yu kantan
ObjectiveThe period during the deposition of the Middle-Late Ordovician Kelimoli-Lashizhong formations witnessed a key transition of the tectonic framework along the western margin of the Ordos Basin. Investigating the lithofacies paleogeography of these

Carbon Isotope Evidence for Ordovician Marine Hydrocarbon Source Rocks in Ordos Basin, North China

, 2011
Ordos Basin is the second largest sedimentary basin in China with gigantically thick Paleozoic marine sedimentary strata. Geochemical analyses show that the carbon isotope compositions of the Ordovician are less influenced by post-depositional ...

Spatial Distribution and Conservation Prioritization of Medicinal Gymnosperms in China Using an Optimal Set‐Cover Approach

Ecology and Evolution, Volume 16, Issue 5, May 2026.
The study identified 41 priority conservation grids and 8 critical conservation gaps not covered by national reserves for medicinal gymnosperms. We proposed a practical, multi‐dimensional framework for their conservation. ABSTRACT To elucidate the geographical distribution patterns and hotspots of medicinal gymnosperms in China, providing a scientific ...
