NEW METHODS OF REGIONAL EXPLORATION FOR BLIND MINERALIZATION - APPLICATION IN THE USSR

This paper briefly reviews and draws attention to more detailed reports in the USSR literature for new methods of exploration for blind mineralization. There are based on the selective extraction of trace elements in mobile form from bedrock and soil. These are: (1) regional exploration using organically bound forms of elements (MPF); (2) elements complexed by secondary iron and manganese oxides (TMGM); and (3) electrogeochemical (partial) extraction of elements (CHIM). Results are given for the application of the methods to several areas of the USSR. These results show that the methods can detect blind mineralization at a depth of 500 m or more in various landscape and climatic environments. The MPF and TMGM methods are applied at the regional level to identify prospective target areas, while the CHIM method is for detailed exploration.
