Helium in soil-gas and helium/radon in ground water in the vicinity of a south Texas uranium roll-type deposit

A survey was run in the vicinity of a south Texas uranium roll-type deposit to determine the general concentration of helium in the soil gas and helium/radon ratios in the ground water for deposits of this nature. The helium in soil-gas concentrations are typical of the concentrations found associated with other low-grade uranium deposits in other areas. The distribution of the values probably reflects local structure and is influenced by surface activities such as farming and mining. The helium/radon ratios in water strikingly reveal the known orebody, and some samples taken for background information may indicate the presence of nearby mineralized areas.
