Influence of volcanic and hydrothermal activity on organic matter enrichment in the Upper Triassic Yanchang Formation, southern Ordos Basin, Central China

, 2020
Based on the field investigation of oil shales in the southern Ordos Basin, detailed observations, and systematic sample analyses of core samples from a well that penetrated an oil shale, the influence of volcanic and hydrothermal activity on the Chang 8–

Depositional and diagenetic processes in volcanic matrix‐rich sandstones from the Shanxi and Shihezi formations, Ordos Basin, China: Implication for volcano‐sedimentary systems

Basin Research, 2022
Volcanic eruptions can provide large amounts of sedimentary materials and expose fluvial valleys or lakes to catastrophic hyperpycnal flood events, but this process has not been documented in detail.

Is the Ordos Basin floored by a trapped oceanic plateau?

Earth and Planetary Science Letters, 2015
Abstract The Ordos Basin in China has about 10 km of Neoarchean to Quaternary sediments covering an enigmatic basement of uncertain origin. The basement is tectonically stable, has a thick mantle root, low heat flow, few earthquakes, and has been slowly subsiding for billions of years.

Astronomical calibration of a ten‐million‐year Triassic lacustrine record in the Ordos Basin, North China

Sedimentology, 2022
The division of geological time is of general interest as this allows a better understanding of the geological processes and Earth's evolutionary history.

Coal Resources and Tectonic Division of Ordos Basin

Advanced Materials Research, 2013
The Ordos Basin is the richest area of coal resources in China, which has an important position in China's coal resources prospecting and exploitation. Through the application of coalfield geology and geodynamics, this paper analyzes the distribution of coal resources of the Ordos Basin. It carries out the research in coalfield tectonic zoning, and the

Pore structure and its fractal dimensions of transitional shale: A cross-section from east margin of the Ordos Basin, China

Fuel, 2019
Shales deposited in marine – continental transitional environments are well developed in the Upper Paleozoic in China with abundant gas resources. The pore structure and its controlling factors of the transitional shales may differ compared to marine and

Pore–throat structure and fractal characteristics of tight sandstones in Yanchang Formation, Ordos Basin

Marine and Petroleum Geology, 2020
Pore–throat structure is a key factor that influences the storage and fluid flow capacity of tight sandstone reservoirs. By performing petro-physical characteristic tests, scanning electron microscopy, and casting thin sections, the main pore types of ...

Major and trace element geochemistry of the lacustrine organic-rich shales from the Upper Triassic Chang 7 Member in the southwestern Ordos Basin, China: Implications for paleoenvironment and organic matter accumulation

, 2020
Lacustrine organic-rich shales are widespread in the Upper Triassic Yanchang Formation Chang 7 Member of the Ordos Basin. However, information on the short-term climate evolution within the Chang 7 Member is still lacking, and the mechanism of organic ...

Effects of deposition and diagenesis on sandstone reservoir quality: A case study of Permian sandstones formed in a braided river sedimentary system, northern Ordos Basin, Northern China

, 2021
The impacts of deposition and diagenesis on sandstone reservoir quality have been extensively discussed over the years. But the research on how depositional factors control the reservoir quality by affecting diagenesis is rarely involved.

Late Paleozoic provenance shift in the east-central Ordos Basin: Implications for the tectonic evolution of the north China Craton

, 2021
Detrital minerals are important recorders of sedimentary transport and provenance, both of which have significant implications for basin genesis and tectonics.
