本文研究了水中铀、镭、钍放射性同位素比值分布特征;提出了赣州南部花岗岩地区放射性同位素比值的判别指标,论述了应用~(226)Ra/~(228)Ra和~(230)Th/~(232)Th比值联合作图判别水异常成因,是一种有找矿意义的途径;列举了隘高岩体、大埠岩体、大富足岩体等地区应用同位素比位判别矿化引起的放射性水异常找矿实例;肯定了应用水中放射性同位素比值判别水异常找矿价值这一新方法的可行性,并就完善和改进该方法提出一些设想和建议。
In this paper, the radioactive isotope ratio distribution of uranium, radium and thorium in water was studied. The discriminant index of radioisotope ratio in granite area in southern Ganzhou was put forward. The application of 226 Ra / 228 Ra and 230 Th / (232) Th mapping to determine the cause of water anomalies is a way to prospecting significance. The isotopic ratios of the Aitao massif, the Da port massif, Radioactive water anomalous ore prospecting examples; affirmed the feasibility of using water radioisotope ratio value of water anomalous prospecting value of this new method is feasible, and to improve and improve the method proposed some ideas and suggestions.
