Summary:
The results of experimental application of the technology of remote sensing data (satellite images) frequency-resonance processing and interpretation with the aim of studying the internal structure of diamond-bearing kimberlite pipes are analyzed. The experiments were carried out at the locations of the well-known kimberlite pipes Udachnaya, Mir (Yakutia, Russia), Letseng-La-Terae (Kingdom of Lesotho), Diavik (Canada), and also in the area of the Klyuchevskaya volcano group in Kamchatka. By the vertical scanning of the cross-section in the central parts of the pipes the depths of the kimberlites roots and the intervals of anomalous responses (signals) at the resonant frequencies of diamonds fixation have been determined. Experimental studies have shown that: a) the frequency-resonance method of remote sensing data processing and interpreting can be used for operative reconnaissance surveys of large blocks and local areas in remote regions; b) the active use of mobile and direct-prospecting methods during the practical problems solving will help to speed up the exploration process for ore and combustible minerals.
