### Planar Anomaly Characteristics of Geoelectrochemical Extraction Elements
Upon encountering reducing barriers, such as organic matter and pyrite, within carbon-silica mudstones, U\({}^{6+}\) is reduced to U\({}^{4+}\), resulting in the precipitation of uranium minerals. AsS\({}_{3}\)\({}^{-}\) either combines with Fe to form arsenopyrite or adsorbs onto the surface of pyrite. Common uranium ore assemblages in the study area include pitchblende-arsenopyrite-galena-pyrite associations. Consequently, the anomalous distribution of As serves as an effective indicator of uranium mineralization. The anomalous region of Pb spans an area of 0.13 km\({}^{2}\), with a peak value of 16.75 \(\times\) 10\({}^{-6}\). The long axis of the anomaly trends in a north-northeast direction, and its concentration center is inferred to align along northeast-distributed faults in a beaded pattern. Pb functions as a comprehensive tracer of hydrothermal activities, uranium migration and enrichment, and mineralization ages [45]. The geochemical behavior of deposits is closely linked to the activation-precipitation process of uranium. A significant positive correlation exists between Pb and U in ores, making Pb a key associated element for uranium exploration [46]. The Th element anomaly is situated at the intersection of the central structure within the study area. Its long axis extends in the northwest direction. The anomaly covers an area of 0.11 km\({}^{2}\), with a peak value of 36.52 \(\times\) 10\({}^{-6}\). Measurement lines L01 and L04 traverse the inner, middle, and outer zones of the anomalies induced by high localized values. As a decay product of the U element, the Th element anomaly primarily corresponds to moderately acidic magmatic rock masses and alkaline rock bodies associated with multi-stage uranium-bearing activities [47]. Furthermore, granite and carbon-silicone-mudstone uranium mineralization exhibits a close relationship with the spatial distribution of the Th element anomaly. The W element anomaly is predominantly concentrated in survey lines L01 and L04. Extending along the northwest direction, faults are distributed in a linear pattern, with an anomalous area of 0.06 km\({}^{2}\) and a peak anomaly value of 10.83 \(\times\) 10\({}^{-6}\). Based on the known section of line L00, lens-shaped scheelite occurs within the uranium-bearing layer of the study area. These scheelite deposits exhibit a close genetic and spatial relationship with uranium orebodies. According to previous studies, pitchblende has been found to contain relatively high concentrations of W. Under microscopic observation, white tungsten ore primarily occurs as net-like veins interspersed within pitchblende. Its strong depletion of heavy rare earth elements (HREEs) aligns with the characteristics of the northern Dushiling white tungsten deposit; however, the occurrence of uranium mineralization is significantly later than that of regional tungsten mineralization. These features suggest that tungsten source layers that were formed early may provide some ore-forming materials for subsequent uranium mineralization [2]. The Mo element anomaly is predominantly situated in the northern and central regions of the study area, exhibiting a band-like and bead-like distribution along structural trends. The anomalous area spans 0.11 km\({}^{2}\), with a peak value of 17.71 \(\times\) 10\({}^{-6}\). For carbon-silicon-mudstone uranium deposits, the Mo element often demonstrates superior indicative properties compared to the U element. In shallow continental shelf sediments, abundant organic matter, phosphorus, iron, and manganese oxides are present, which can reduce multivalent elements such as molybdenum, uranium, and vanadium to lower-valence ions through reactions with hydrogen sulfide, thereby enriching them [42; 48].
