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 ...

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 ...
