SUMMARY

Dividing up exploratory deposit groups and orienting the exploratory methods

for uranium ores in Việt Nam

Nguyễn Phương, Doãn Huy Cẩm, Nguyễn Quang Hưng

The works of investigation and evaluation of uranium ores in Việt Nam had been paid attention since the 80 decade of the XX century. With the limited degree of research, however, the exploratory experiences are really deficient. Thus, the investigation on types of forming origins and types of industrial origins, and the determination of basic elements for dividing and arranging the groups of exploratory deposits and exploratory systems corresponding with each type of origin of uranium ores, are essential. These works have not only the scientific value, but also the practical one. Basing on the synthesis of data on uranium exploration in different places and correlation with the schema of division of the International Atomic Energy Agency, we can recognize the existence of 6 types of forming origin of uranium ores in Việt Nam, among them, the uranium ores formed in sandstone in the Nông Sơn basin is of high potential. At the same time, we initially suggest the standards to divide different groups of exploratory deposits, confirm that the uranium ores in Việt Nam belong to the type III (in the group of exploratory deposits), and suggest a combination of exploratory methods applying in exploratory works of uranium ores and orienting the exploratory net which has been arranged for every group of exploratory deposits.
