Study on sequence stratigraphy from benxi to taiyuan formation in Northeastern Ordos Basin [PDF]

Procedia Earth and Planetary Science, 2009
AbstractBased on the study of the vertical sedimentary sequence, we recognize the assemblage of vertical lithology, the geochemical test result of mudstone sample, and the characteristics of logs, the sequence stratigraphic interfaces such as regional unconformity, regional tectonic regime interface, sedimentary system interface, transgression surface ...

Detrital zircon U–Pb geochronology from the Upper Carboniferous sediments of Benxi Formation in the North China Craton: implications for tectonic-sedimentary evolution [PDF]

Comptes Rendus. Géoscience, 2020
The provenance of the Upper Carboniferous Benxi Formation in North China Craton (NCC) has been considered as the northern margin of the NCC, not the North Qinling Orogenic Belt.

Constraints of nonseismic geophysical data on the deep geological structure of the Benxi iron-ore district, Liaoning, China

Open Geosciences, 2020
The Benxi area in Liaoning Province is one of the most important iron-ore districts in China. This study uses nonseismic geophysical data (in the form of gravity–magnetic–magnetotelluric data) and based on the section modeling method to model the deep ...

Genesis of Calcite Veins in 8# Coal Seam of the Upper Carboniferous Benxi Formation, Southeastern Margin of Ordos Basin

Minerals, 2023
The 8# coal seam in the Benxi Formation of the southeastern margin of the Ordos Basin is a deep coal seam with abundant coalbed methane resources. Calcite veins are commonly developed within the 8# coal seam, and their formation processes and mechanisms have significant implications for the enrichment of deep coalbed methane.

Early–Late Carboniferous Tectonic Evolution of the Northern North China Craton (NE China): Constraints From Zircon Ages, Geochemistry, and Crustal Thickness Modeling

Geochemistry, Geophysics, Geosystems
The tectonic evolution of the northern margin of the North China Craton (NCC) remains controversial. In this study, we obtained zircon U–Pb ages, geochemical data, and Sr–Nd isotopic data for volcanic rocks, and detrital zircon ages for sedimentary rocks

Spatial Variations in Methane Content and Their Main Controlling Factors of the Deep‐Buried Coalbed in the Nalinhe–Hengshan Area, Ordos Basin

Energy Science & Engineering
Deep‐buried coalbed methane (DCBM) exhibits significant exploration potential, though with notable spatial variations in gas content. The primary geological factors controlling the differential enrichment of DCBM and their respective influences remain ...
