Helium Accumulation and Uranium Deposit in the Chu-Sarysu Basin–A Symbiotic Process

Helium is an inert gas produced by the radioactive decay of uranium and thorium atoms. Although its creation and dissemination are linked to uranium resources, the symbiotic process remains unknown. This research uncovers the symbiotic relationship between water-soluble helium and uranium mineralization through quantitative investigation of water helium anomalies near uranium mineralization by summarizing the distribution of helium (He) and Uranium Mineralization in the Chu-Sarysu Basin. The Chu-Sarysu Basin is a late Paleozoic Mesozoic Cenozoic Superimposed basin developed on crystalline Precambrian basement. There are fourteen helium gas fields discovered. Helium geological deposits are estimated to be at 104 million m3, with a helium content of 0.11–0.83%. They are all typical rich-helium tiny gas reservoirs. It is demonstrated that the rich-uranium basement in the basin is the material basis for the formation of rich-helium gas reservoirs and rich-uranium deposits by evaluating the distribution characteristics of water-soluble helium close to the Uvanus uranium deposit in the Chu-Sarysu Basin. The two mineral deposits migrate over a shared channel in the deep fault zone. The two mineral deposits migrate using the hydrothermal solution and heat field as their common carrier. The accumulation of helium in the deep crust and in the abundant U and Th strata along the faults is another source of the water-soluble helium in addition to uranium mineralization. The strength of the water helium halo is inversely correlated with distance from the uranium ore body in a specific region surrounding it. The amount of water-soluble helium in the borehole gradually declines from deep to shallow in the vertical direction. The water helium halo, water uranium halo, and gamma anomaly field all indicate uranium mineralization. It is possible to effectively explore for uranium deposits and helium gas reservoirs using the water helium anomaly surrounding uranium mineralization.
