Genesis of green sandstone/mudstone from Middle Jurassic Zhiluo Formation in the Dongsheng Uranium Orefield, Ordos Basin and its enlightenment for uranium mineralization

China Geology, 2020
: The middle Jurassic Zhiluo Formation in the Dongsheng is comprised of a big set of green sandstone/mudstone with most of uranium orebodies occurring in close proximity to its footwall. By synthesizing field observations, region analysis, data collected

Detrital Zircon U–Pb Geochronology as an Indicator of Provenance in the Zhiluo Formation of the Western Ordos Basin, China

Arabian Journal for Science and Engineering, 2020
Detrital zircon grains were collected from six samples of sedimentary rock from the Middle Jurassic Zhiluo Formation in the western Ordos Basin of China. U–Pb isotopic geochronology data were measured and used to assess the provenance and directions of sediment transport of these grains. Five age populations were recognised amongst the U–Pb age spectra:

Pore Structure Characteristics and Main Control Factors of Sandstone in the Jurassic Zhiluo Formation in the Northern Ordos Basin

Minerals (Basel, Switzerland), 2023
The Jurassic Yan’an Formation in the Ordos Basin is one of the main coal seams mined in the basin, and the enrichment of water bodies in the upper part of this coal seam is closely related to the sand bodies in the Zhiluo Formation. This study is based on the use of core observations in the northern part of the Ordos Basin for studying the pore ...
