Groundwater Systems and Resources in the Ordos Basin, China

Acta Geologica Sinica, 2008
AbstractThe Ordos Basin is a large‐scale sedimentary basin in northwestern China. The hydrostratigraphic units from bottom to top are pre‐Cambrian metamorphic rocks, Lower Paleozoic carbonate rocks, Upper Paleozoic to Mesozoic clastic rocks and Cenozoic deposits. The total thickness is up to 6000 m.

Jurassic Deformation in and Around the Ordos Basin, North China

Earth Science Frontiers, 2007
Abstract 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 ...

The composition of shales from the Ordos basin, China: effects of source weathering and diagenesis

open access: yesSedimentary Geology, 1998
The Ordos basin, situated in northwestern China, is the biggest Mesozoic terrigenous sedimentary basin developed on the North China Platform. The geochemical data imply that shales from the Ordos basin were mainly derived from a source area with an ...

Pore structure representations based on nitrogen adsorption experiments and an FHH fractal model: Case study of the block Z shales in the Ordos Basin, China

, 2021
Shale oil/gas is a crucial development in the exploitation of unconventional reservoirs. However, owing to the small pore size and complicated structure, finding an inexpensive and accurate method of accurately representing the pore structure has become ...

Hydrochemical assessments and driving forces of groundwater quality and potential health risks of sulfate in a coalfield, northern Ordos Basin, China.

Science of the Total Environment, 2022
Groundwater is the primary water source in coalfields under arid and semiarid climates. However, the problem of excessive concentrations of sulfate, which is a constant component in coalfields, and its potential health risks are often neglected in ...
