Biological mechanism of paleokarst developed in the Ordos Basin

2011 International Symposium on Water Resource and Environmental Protection, 2011
This paper demonstrated the biological mechanism of paleokarst developed within the Ordovician formation in the Ordos Basin. An experiment in laboratory was designed for understanding the water-rock interaction with sulfate-reducing bacteria. The study is focused on the geochemical processes in the bacteria-water-rock system by tracing stable sulfur ...

GEOHISTORY MODELLING OF CRATONIC BASINS: A CASE STUDY OF THE ORDOS BASIN, NW CHINA

Journal of Petroleum Geology, 1997
This paper describes geohistory modelling as applied to the intracratonic Ordos Basin in NW China; corrections for compaction, the restoration of unconformities and the effects of tectonic subsidence are discussed.The thickness of a modelled layer of sediments can be determined at any time in the past by taking account of a correction for compaction ...

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.

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

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

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 ...

Research on Sedimentary Environment of the Wayaobao Formation in Ordos Basin

Applied Mechanics and Materials, 2013
Wayaobao Formation of late Triassic, in Ordos Basin is composed of clastic rocks, such as grey green thick-bedding medium-coarse-grained lithic arkose, lithic feldspathic sandstone, fine-medium-grained lithic feldspathic greywacke, quartzose feldspathic sandstone, et al.

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

Genesis of tight sand gas in the Ordos Basin, China

Organic Geochemistry, 2014
Abstract Based on molecular and stable carbon isotope composition of a large collection of gas samples and integrated with the geological context, this article discusses the genesis and migrational characteristics of natural gases from the giant tight sand gas fields of the Upper Paleozoic strata, Ordos Basin (UPOB).
