摘要
对地壳中U、Th、K分布特征带的研究,得到了离子迁移定律,离子成矿说和矿产地质调查评价五法则。华南2个研究区的实践初步验证它们是正确的,两区内都存在U、Th、K分布特征带,已知重要铀矿床和非铀矿床,预测出的富铀靶区,多金属矿远景区都分布在U、Th、K特征带范围内,在面上构成资源网,线上构成资源索。重要已知矿床,富铀靶区,多金属远景区都受构造、接触带等控制,多产在老地层内。航空伽马能谱的找矿潜力体现在航空伽马能谱异常和各矿种重要矿床形成机理相同的2个方面。航空伽马能谱查明的U、Th、K分布特征带是研究离子运动应力带的基本事实根据。
Researches on the distribution of U, Th and K in the crust yielded the ion migration law, the ion metallogenic hypothesis and the five laws for geological survey and appraisal of ore resources. Preliminary inspection in two study areas of South China has proved their correctness. There exist U, Th, K characteristic distribution zones in these two areas, and the known important uranium and non - uranium deposit, the predicted uranium-rich target districts as well as the polymetallic prospect districts all lie within the characteristic distribution zones. They regionally form resources networks and linearly form resources ropes. The known important uranium and non-uranium deposits, the predicted uranium-rich target districts as well as the polymetallic prospect districts are all controlled by structures and contact zones and occur in old strata. The ore-prospecting potential of the airborne gamma energy spectrum technique lies in the consistency between the airborne gamma energy spectrum anomalies and the formation mechanisms of important deposits of various ore species. The U, Th, K characteristic distribution zones disclosed during the airborne gamma energy spectrum survey provide basic facts for the study of ion movement stress zones.
