Geology and exploration of oil and gas in the Ordos basin
Applied Geophysics, 2004The Ordos basin is rich in oil and gas resources. The structures in the basin are generally rather gentle. Most of the oil and gas pools already found are belong to the types of lithologic, litho-1 stratigraphic and paleo-geomorphic with thin reservoirs.

Is the Ordos Basin floored by a trapped oceanic plateau?
Earth and Planetary Science Letters, 2015Abstract 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.

Biological mechanism of paleokarst developed in the Ordos Basin
2011 International Symposium on Water Resource and Environmental Protection, 2011This 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 ...

Depositional Evolution and Coal Accumulation of Ordos Basin
2020Ordos Basin, a huge intracontinental depression, influenced by Pacific structural domain together with Tethya, is formed during Mesozoic Era. Evolutional process of the depression can be divided into four epoches Early Jurassic to early period of Middle Jurassic, Middle Jurassic, Late Jurassic and Early Cretaceous, of which, Early Jurassic to early ...

Coal Resources and Tectonic Division of Ordos Basin
Advanced Materials Research, 2013The 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

Jurassic Deformation in and Around the Ordos Basin, North China
Earth Science Frontiers, 2007Abstract The Jurassic era was an important period for tectonic development of the East Asia continent in general, and can be divided into two different deformation stages around the Ordos basin in particular. It was under weak extension during the Early to Middle Jurassic, with the stretching direction in N-S to NNE-SSW, and the stretching ...

Basement faults and volcanic rock distributions in the Ordos Basin
Science China Earth Sciences, 2010Volcanic 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.

Burial Metamorphism of the Ordos Basin in Northern Shaanxi
Acta Geologica Sinica - English Edition, 1993Abstract 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 ...
