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。
In this paper, from the perspective of geochemical exploration, we discussed the sub-city features of 鑀 in rocks, ores and soils, and their relationship with uranium mineralization. Based on the relationship between 鑀 and uranium and radium, the origin of their decay and the different geochemical properties, this paper discussed the application of 锾-law in uranium exploration. Through a large number of comprehensive comparisons on four different types of uranium deposits (spots) in four different types in western Hunan and southern Hunan, it is proved that it not only has its own uniqueness in the study of radioactive equilibrium destruction of uranium and radium, but also can be inferred that Geochemical changes in order to explain the genesis of uranium deposits, evaluation of anomalous points, belts, so uranium prospecting exploration is an effective tool to find the blindness. It has the advantages of simple and convenient working methods in the field, intuitive display, less influencing factors and comprehensive comparison. Since redox reactions are extensively involved in the formation and destruction of uranium deposits, there is still good evidence that other methods (such as gamma, uranium, radon and their daughter measurements) are not clearly reflected.
