砂岩型铀矿找矿有了新“钥匙”
Ke Ji Ri Bao· 2025-06-06 01:21
Core Viewpoint - The introduction of a new sandstone uranium mineralization theory, "exudation sandstone uranium mineralization theory," is expected to enhance uranium resource exploration in China, particularly in the northern regions where sandstone-type uranium deposits are prevalent [1][2]. Summary by Sections Uranium Resource Types - China's uranium resources are categorized into four main types: sandstone, granite, volcanic, and carbon-silicate mudstone, with northern regions predominantly featuring sandstone-type uranium deposits and southern regions characterized by hard rock-type deposits [1]. Traditional Uranium Mineralization Theory - The traditional sandstone uranium mineralization theory posits that surface oxygenated water carries uranium into the ground, where it precipitates at the redox interface. This theory has been a guiding principle for uranium exploration in regions like Ili and Turpan [1]. Limitations of Traditional Theory - The traditional theory primarily targets gray sandstone layers and focuses exploration efforts on the basin edges and shallow depths, which limits its effectiveness in explaining uranium mineralization in red and mixed-color sedimentary sandstone layers [1][2]. New Exudation Sandstone Uranium Mineralization Theory - The new theory suggests that organic-rich fluids from deep layers carry uranium to shallower sandstone layers under pressure and temperature conditions, leading to uranium precipitation in favorable storage spaces [2]. Exploration Achievements - Based on the new theory, significant uranium exploration successes have been reported in various basins, including the discovery of sandstone uranium deposits at depths of nearly 1400 meters in the Ordos Basin and new findings in the Qaidam and Tarim basins [2]. International Recognition - The new theory has been recognized as a significant advancement in uranium exploration methodologies, with international experts noting its importance for guiding exploration efforts, as evidenced by its application in countries like Uzbekistan [2].
