###### Abstract
As a geochemical exploration method integrating disciplines such as geochemistry, geo-electrochemistry, and geophysics, geo-electrochemical integrated technology's origins trace back to the CHIM developed by Soviet scholars in the late 1960s [6]. It was introduced to China in the 1980s by [PERSON] and [PERSON]. In 1989, [PERSON] proposed standardizing the technology. Significant methodological and technological enhancements were achieved in 2003 by [PERSON] and [PERSON], particularly through the development of low-voltage-dipole geoelectrical extraction de-vices, facilitating substantial advancements in China. In 2017, scholars such as [PERSON] and [PERSON] drafted the \"Technical Regulations for Geo-electrochemical Measurement (Draft for Comment)\" jointly. Following over three decades of development, the electrochemical mechanism behind Earth's halo formation has been progressively refined, and associated instrumentation has undergone significant upgrades. Numerous scientific research and industrial organizations have achieved significant success in exploring concealed mineral deposits across various mineral types and geological coverage areas by employing geo-electrochemical integrated technology. The minerals involved encompass over ten categories, including gold, silver, copper, lead, zinc, tungsten, tin, arsenic, antimony, nickel, and uranium. For instance, in the arid Gobi Desert region of Qinghai, China, this technique demonstrated significantly superior precision in targeting lead-zinc ore bodies at approximately 100 m depth compared to displaced rock geochemical surveys [7]. In the thick loess-covered terrain of Shanxi, soil geochemical surveys yielded only weak responses to gold ore bodies buried at depths of 38-200 m, whereas distinct geo-electrochemical anomalies accurately reflected the location of gold mineralization [7]. On the frozen plateau of Tibet, soil geochemical surveys could only identify shallow mineralization, while geo-electrochemical surveys revealed clear anomalies directly above the ore bodies [8]. Particularly in the eolian sand-shallow cover area of Inner Mongolia, 1:50,000 scale geo-electrochemical surveys successfully delineated multi-element anomalous targets coincident with known lead-zinc-silver mineralization. Eventually, through geophysical IP (Induced Polarization) gradient surveys and drilling programs, a 6 m thick Ag-Cu-rich ore body was discovered at a depth of over 540 m, achieving a breakthrough in mineral exploration. In contrast, the soil geochemical survey only showed sporadic anomalies [9]. These collective results validate the efficacy of geo-electrochemical technology in thick-cover regions. Consequently, they provide the methodological foundation for this study's application in targeting concealed carbonaceous-siliceous-pelitic uranium deposits within the thick Quaternary cover sequences of northern Guangxi. The applied techniques have proven effective for deposits of multiple genetic types, and they include the following: high-temperature, medium-temperature, low-temperature hydrothermal, sedimentary exhalative, stratabound, sediment-hosted and modified, volcanogenic, volcanic-sedimentary metamorphic, skarn, and sandstone-hosted deposits [10; 11; 12]. Currently, studies on the application of geo-electrochemical techniques for exploring concealed uranium deposits have covered various regions. These include the Four Mile East and Goulds Dam in Australia; the Dongsheng and Dachengliang areas within the Ordos Basin in Inner Mongolia, China, for sandstone-hosted uranium deposits; the Huxi area, Xiangshan area, and Shengyuan Basin in Jiangxi, China, for volcanic rock-hosted uranium deposits; and the Motianlun area in Guangxi and the Lujing area in Hunan, China, for granite-hosted uranium deposits [13; 14; 15; 16; 17; 18; 19; 20]. Considerable prospecting achievements have been attained in these studies.
