Isotope geochemistry of ore fluids for the Dongsheng sandstone-type uranium deposit, China

Diqiu Huaxue, 2007
The Dongsheng sandstone-type uranium deposit is one of the large-sized sandstone-type uranium deposits discovered in the northern part of the Ordos Basin of China in recent years. Geochemical characteristics of the Dongsheng uranium deposit are significantly different from those of the typical interlayered oxidized sandstone-type uranium ore deposits ...

Ore characteristics of the sandstone-type Daying uranium deposit in the Ordos Basin, northwestern China

Canadian Journal of Earth Sciences, 2017
The Ordos Basin is one of the top oil-, gas-, and coal-producing basins in China and is increasingly recognized as an important uranium mineralization province. Uranium deposits occur near the margin of the basin and are mainly hosted in the sandstones of the Jurassic Zhiluo Formation.

Origin of gray-green sandstone in ore bed of sandstone type uranium deposit in north Ordos Basin

Science in China Series D: Earth Sciences, 2007
Dongsheng sandstone-type uranium deposit is located in the northern part of Ordos Basin, occurring in the transitional zones between gray-green and gray sandstones of Jurassic Zhiluo Formation. Sandstones in oxidized zone of the ore bed look gray-green, being of unique signature and different from one of ordinary inter-layered oxidation zone of ...

Key Ore‐Controlling Factor of Sandstone‐Type Uranium Deposits in Northern Ordos Basin, Constrains on Uranium Metallisation and Exploration

Geological Journal
ABSTRACT The Daying, Tarangaole and Nalinggou uranium deposits in the northern Ordos Basin form a world‐class uranium field, with complex uranium mineralisation processes. Key ore‐controlling factors of these deposits have contributed to the uranium enrichment in different ore‐bearing strata.

Comparative Experiments on Acid Leaching and Bioleaching to a Sandstone Type Uranium Ore

Advanced Materials Research, 2015
512 uranium deposit, located in the northwest of China, is one of the largest in-situ leaching uranium mine in China. In the last 2 decades, The V cyclothem Deposit in 11 mining areas were successively mined by acid in-situ leaching. The uranium recovery rate in the roll body was very high, in contrast it was very low in wing body.

Concepts of genesis of sandstone-type uranium ore deposits

Economic Geology, 1963
Although the sources of uranium in sandstone-type ores are in most cases obscure, the formation of the ore deposits can be attributed on the basis of sulfur isotopic data to the precipitating action of hydrogen sulfide of bacteriological origin. In some areas deposition has been related heretofore to natural gas, but the isotopic evidence does not ...

Uraniferous Organic Matter in the Sandstone-Type Uranium Ore from Domiasiat, Meghalaya, India

Journal Geological Society of India, 1995
Abstract Uranium in the sandstone-hosted uranium deposit at Domiasiat, Meghalaya is mainly associated with organic matter (OM), which is also enriched in several trace elements, viz. Zn, Pb, Ni, V, Co, Ba, Sn, Mo, Cr, Ag, P etc. This paper is an attempt to characterize and discuss the origin of the OM and the associated uranium.
