Purpose. The results of the mobile methods application on the sites of the active volcanic complexes location on Earth, Mars and the Moon are presented. Experimental studies were carried out in order to establish the possibility of using directprospecting technology for studying the deep structure of geological complexes of various types, as well as working out and improving methodological techniques for instrumental measurements conducting during the reconnaissance and detailed research performing.
Design/methodology/approach. The developed mobile and low-cost technology include modified methods of frequency-resonance processing and decoding of satellite images and photo images, vertical electric-resonance sounding (scanning) of a cross-section, as well as a method of integrated assessment of the prospects of oil and gas potential of large prospecting blocks and license areas. Separate methods of this direct-prospecting technology are based on the principles of the “substance” paradigm of geophysical research, the essence of which is to search for a specific substance — oil, gas, gas condensate, water, gold, zinc, etc.
Findings. The presence of carbon dioxide, the synthesis of which is carried out in volcanic complexes, filled with sedimentary rocks of 1-6 groups have established in the gas plumes of two volcanoes by instrumental measurements. In the area of the Fukutoku-Okanoba volcano, additional evidence has been obtained in favor of the existence in young (including active) volcanic complexes of boundaries for the synthesis of hydrocarbons, carbon dioxide and water at depths of 11 km and 13 km. On the area where the Klyuchevskaya Sopka volcano is located, a granite volcano with a root at a depth of 996 km was discovered. At a depth of 13.6 km, signals from granites were recorded at frequencies of nickel, osmium, iridium,
platinum, gold, and mercury. The upper part of the cross-section of Stromboli volcano is composed of marls, and responses at the frequencies of chlorine, hydrogen, and hydrochloric acid were recorded from the gas plume. When processing a fragment of a gas plume on the surface of Mars, signals from chlorine, hydrogen and hydrochloric acid were also recorded. In the area of the Alphonse crater on the Moon, volcanic structures filled with ultramafic rocks, kimberlites (without diamonds) and marls were discovered. In the area of an active volcano on the La Palma Island confirmed the facts about the possibility of hydrocarbon synthesis in some types of granite volcanoes at the 57 km depth, and additional evidence was obtained in favor of the existence of another oil, condensate and gas synthesis border at a depth of 11 km. Materials of the reconnaissance survey of the site of the epicenters of strong earthquakes location in the area of Mayotte Island (Indian Ocean) confirm the assumptions of researchers about the connection of earthquakes with volcanic activity. The results of the experimental reconnaissance works carried out indicate the feasibility of using mobile direct-prospecting methods of frequency-resonance processing and decoding of satellite images and photographs to study the deep structure of areas where volcanic complexes are located and to search for combustible and ore minerals.
The practical significance and conclusions. The results of the experimental reconnaissance work carried out indicate the advisability of using mobile direct-prospecting methods of frequency-resonance processing and decoding of satellite images and photographs to study the deep structure of areas, where volcanic complexes are located, and to search for combustible and ore minerals.
