Burial Metamorphism of the Ordos Basin in Northern Shaanxi

Acta Geologica Sinica - English Edition, 1993
Abstract Burial metamorphism has been found in the Ordos basin of northern Shaanxi. On the basis of a rather intensive study of burial metamorphism of sandstone, it has been shown that the evolution from diagenesis to metamorphism involves four stages: cementation of clay minerals, regrowth of pressolved quartz and feldspar, cementation of carbonates ...

Diagenetic evolution and densification mechanism of the Upper Paleozoic tight sandstones in the Ordos Basin, Northern China

, 2021
The Upper Paleozoic sedimentary succession in the Ordos Basin, Norther China, contains typical tight gas sandstones. Densification process and diagenetic evolution of these sandstones are poorly known but are important for exploration of reservoirs ...

Clay mineral content, type, and their effects on pore throat structure and reservoir properties: Insight from the Permian tight sandstones in the Hangjinqi area, north Ordos Basin, China

, 2020
Clay mineral content and pore throat structure, including type, morphology, size distribution, and porosity and permeability, are very important in factors that control gas storage in tight sandstone reservoirs. In this study, integrated thin section and

Tectonic Response Characteristics of the Yanshan Movement in the Ordos Basin - Insights from the Yanshanian Unconsolidated Surface in the Ordos Basin

The Yanshan Movement period (Middle Jurassic-Late Cretaceous) represents a critical period of deformation and magmatic development in China, during which the tectono-sedimentary pattern of the North China Craton underwent a major transformation. A large stratigraphic record is preserved in the relatively stable Ordos Basin. It provides a possibility to

Basement faults and volcanic rock distributions in the Ordos Basin

Science China Earth Sciences, 2010
Volcanic rocks in the Ordos Basin are of mainly two types: one in the basin and the other along the margin of the basin. Besides those along the margin, the marginal volcanic rocks also include the volcanic rocks in the Yinshanian orogenic belt north of the basin.

Fractal Distribution of Paleotrough and Exploration Potential in Ordos Basin

2019
In Ordos Basin, gas exploration practice indicated that the spatial distribution of Ordovician paleotrough played an important role in gas reservoirs quality. In order to optimize exploration target, the paleotrough distribution was studied by fractal theory. There are three procedures in practical operation. Firstly, the relationship between reservoir
