Sequence stratigraphy of the Middle Jurassic Yan’an Formation (NE Ordos Basin, China), relationship with climate conditions and basin evolution, and coal maceral’s characteristics

open access: yesFrontiers in Earth Science, 2023
The Yan’an Formation of the Ordos Basin in North China is among the largest and most extensively studied Jurassic coal reservoirs in the world. The lacustrine Yan’an Formation was investigated near Dongsheng (Ordos Basin, China) in its sequence ...

Height Prediction of Water-Conducting Fracture Zone in Jurassic Coalfield of Ordos Basin Based on Improved Radial Movement Optimization Algorithm Back-Propagation Neural Network

open access: yesMathematics
The development height of the water-conducting fracture zone (WCFZ) is crucial for the safe production of coal mines. The back-propagation neural network (BP-NN) can be utilized to forecast the WCFZ height, aiding coal mines in water hazard prevention ...

Evolution of prototype basin and change of tectonic-sedimentary pattern in Paleozoic, Ordos Basin

open access: yesShiyou shiyan dizhi, 2022
The Ordos Basin is a craton basin developed based on the Precambrian rift system during Permian. It has experienced two stages of evolution including the Early Paleozoic craton marginal depression and Late Paleozoic intra-craton depression.

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.

Water-flooding characteristics of lithologic reservoir in Ordos basin [PDF]

open access: yesScientific Reports, 2021
AbstractDue to the poor situation of water-flooding mechanism research on Chang 4 + 5 reservoir of Ordos basin, the authors quantitatively studied the influence factors of water-flooding characteristics by sedimentology, casting thin sections, constant-speed mercury injection, scanning electron microscope as well as production records.

Platinum Group Element Traces of CAMP Volcanism Associated With Low‐Latitude Environmental and Biological Disruptions

open access: yesGeophysical Monograph Series, Page 263-304., 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.

Status-quo of proved oil/gas initially-in-place in China as of 2020 and its variation trend in the past decade

open access: yesEnergy Geoscience, 2022
This study analyzes the status-quo of the proved oil/gas initially-in-place and its variation trend, the proved undeveloped oil/gas initially-in-place, and the remaining proved technically recoverable reserves (TRR) of oil/gas in China as of 2020 based ...

Triassic hydrothermal chimneys from the Ordos Basin of Northern China [PDF]

open access: yesScientific Reports, 2021
AbstractBecause few well-preserved hydrothermal chimneys have been found in terrestrial sedimentary rocks, research on paleo-thermal vents in geological history is relatively sparse. In this study, we present our original discovery of “hydrothermal chimneys” from the Chang 7 source rocks of the Triassic Yanchang Formation in the Ordos Basin, China, and

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 ...
