| 摘 要： | 本文从化探角度出发,讨论了鑀在岩、矿石和土壤中的分市特征及其与铀成矿作用之间的关系。以鑀和铀、镭之间,其衰变成因联系和不同的地球化学性质为基础,对锾法在寻找铀矿中的应用进行了初步探讨。通过在湘西,湘南四种不同类型的20个铀矿床(点)上的大量综合对比,证明了它不仅对铀、镭放射性平衡破坏研究有其独特之处,并且可以推测出成矿过程中的地球化学变化,从而解释铀矿床的成因,评价异常点、带,因此是铀矿普查勘探攻深找盲的一种有效手段。它具有野外工作方法简便、显示直观、影响因素少和便于综合对比等优点。由于氧化还原反应广泛参加了铀矿床的形成和破坏,所以在其它方法(如伽玛、铀量、氡及其子体测量)反映不明显的情况下,鑀法仍有较好的显示。

| Abstract: | The distribution of ~(230)Th in soils, rocks and ores and its relationship with respect to uranium ore formation are discussed for its possible use in geochemical cxploration for U, ~(230)Th, U and Ra, being members of the same decay series, are different in their geochemical behavior upon which the study is orientated. Twenty uranium deposits and occurrences located in wert and south. Hunan provincc are tested. Geochemical data obtained are comprehensively correlated. It is suggested that ~(230)Th is useful not only in URa di(?)quilibrium study but also in understanding the geochemical evolution of U ores. The data aid to interpret the genesis of uranium deposits and to assess the radioactive anomalies and uranium-bearing zones. Therefore, it can be adopted as a tool for searching in deep-buried uranium ores. The field procedure is rather simple and flexible to meet any geological environment. It is easy to read out and is less influnced by any kind of interference. In case of disequilibrium caused by oxidation and reduction during the period of ore formation it still gives good indication compared with that of radiometry, radonmetry and geochemical sampling for U. |
