Summary:
The report presents and analyzes the results of the frequency-resonance method of remote sensing data processing and interpretation application on a local area in Ukraine during the zones of polymetallic mineralization searching and mapping. The surveyed license area is of 16.0 km2. For the more detailed work conducting, the area was divided into four fragments. For each fragment the satellite image in scale of 1:8000 have been prepared. Within each image the detection and mapping of anomalous zones of the "ores deposit" type were carried out and the evaluation of anomalous response intensity have been performed. By the processing results the maps of anomalous zones of "deposits of polymetallic ores" type in the scale of 1: 8000 were constructed. For large by size and intensity anomalous zones the coordinates of central points were defined. At these points a vertical scanning of cross-section has been fulfilled to a depth of 200 m. The depth intervals for ore deposits searching were installed. By the characteristics reference frequency (detected on the ores samples) using, the zones of occurrences of copper (Cu), silver (Ag), gold (Au), lead (Pb), zinc (Zn) and iron (Fe) have been determined. According to the results of work the anomalous zones of the “polymetallic ores” type are highlighted within the license area: 14 zones of the "copper sulfide ores" type, 7 zones of "lead ore" (galena) type, 2 zones of the "gold ore deposits" type , 2 zones of "deposits of silver" type and one zone of the "iron-zinc ore" type. The zones names are conditional, because each of them can include in addition to the designated minerals and other ore minerals.
