Geochemical Characteristics of Trace Elements and REEs and their Geological Significance for Uranium Mineralization within the Qianjiadian Sandstone‐Hosted Uranium Deposit, Songliao Basin

Geofluids, Volume 2023, Issue 1, 2023., 2023
The Qianjiadian uranium deposit is a typical interstratified oxidized zone sandstone‐hosted uranium deposit hosted in the Upper Cretaceous Yaojia Formation of the southern Songliao Basin. Despite its significance, little research has been conducted on the relationship between trace elements, REEs, and uranium mineralization in this deposit.

Evolution of Fractal Pore Structure in Sedimentary Rocks

Earth and Space Science, Volume 9, Issue 6, June 2022., 2022
Abstract Geological processes alter pore spaces over time, and their analysis can shed light on the dynamic fractal structure and fluid flow of rocks over time. This study presents experimental evidence to illustrate that the pore fractal structure evolves with sedimentation, carbonate cementation, clay growth, and dissolution.

Extremely High Primary Productivity and Organic Matter Enrichment in Lacustrine Sediments: Late Triassic Chang 73 Sub‐Member, Western Ordos Basin

Geofluids, Volume 2022, Issue 1, 2022., 2022
The 7th member of the Late Triassic Yanchang Formation is the most important Mesozoic source rocks and shale oil reservoir in the Ordos Basin. The hydrocarbon potential and organic matter enrichment mechanism of this organic‐rich member are questioned because of the high heterogeneity of continental sediments. In particular, the lack of drilling in the

Mineral Composition and Full‐Scale Pore Structure of Qianjiadian Sandstone‐Type Uranium Deposits: Application for In Situ Leaching Mining

Geofluids, Volume 2022, Issue 1, 2022., 2022
In situ leaching (ISL) is becoming the main mining practice for sandstone‐type uranium deposits in China. The key to ISL technology is to aid the leaching solution in contacting the ore bed over a large range, which will induce a series of chemical reactions to extract uranium; thus, it is essential to thoroughly understand the reservoir physical ...

Study on the Wettability and Spontaneous Imbibition Characteristics of Lacustrine Shale

Geofluids, Volume 2022, Issue 1, 2022., 2022
Wettability plays a significant role in the exploration and development of shale oil. The wettability affects the oil enrichment and restricts the selection of fracturing fluids. Shale is composed of complex minerals and organic matter. The pores composed of inorganic minerals have water wettability, while the pores composed of organic matter show the ...

Spatial Characteristics and Genesis of Tight Clastic Reservoirs in Yingcheng Formation of Changling Fault Depression in the Southern Songliao Basin

Geofluids, Volume 2022, Issue 1, 2022., 2022
Tight oil and gas has become a hot spot for unconventional oil and gas exploration. How to find high‐quality reservoirs under the conditions of low porosity and permeability has become a key issue restricting tight oil and gas exploration. This paper takes the deep‐seated tight clastic rocks in the Changling fault depression in the Songliao Basin as ...

Multielement Imaging Reveals the Diagenetic Features and Varied Water Redox Conditions of a Lacustrine Dolomite Nodule

Geofluids, Volume 2022, Issue 1, 2022., 2022
The genesis of dolostone has long been puzzling for more than two centuries. Although much work has been done on investigating the process of dolomitization, little emphasis has been put on examining the diagenetic water redox condition with the wealthy geochemical information preserved in primary dolomite, which is believed to archive the aqueous ...
