Abstract

The relevance. The expansion of the mineral resource base of existing mining enterprises requires modern approaches to the study of adjacent areas. One of such modern methods in the study of areas is the use of modern spectral space imagery in order to isolate poten/ tially ore/bearing areas based on structural and material interpretation. The main aim of the work was to develop the criteria for epithermal gold/silver mineralization within the Okhotsk/Chukotka volcanic belt based on materials from remote surveys. The objects of the research were the well/known ore taxa of the southeastern flank of the Ulinskaya mineragenic zone of the Okhotsk/ Chukotka volcanic belt. Methods: processing, spectral analysis and interpretation of modern remote sensing Landsat, Aster and high resolution images Ikonos, WorldView, QuickBird. Results. The authors have developed regional, local and detailed criteria for epithermal Au/Ag mineralization using the example of one of the sections of the Ulinsk mineragenic zone. Structural criteria for the regional level are systems of telescoped ring structures with a diameter of 20–90 km at the junction points of multidirectional faults. Structural and material criteria of the local level are the areas of conjugation of systems of nested coordinated ring structures with sizes from 1 to 10 km with zones of development of Fe/oxide indices. The structural/material criteria of the detailed level include small ring structures made by the bodies of silica of various mineral compo/ sition, associated with zones of development of Fe/oxide indices, within the sections of the propilitic type of alteration. On the basis of the identified features of the structure of the Svetloe ore field, a forecast was made of the prospects for the southern and southeastern flank to identify Au/Ag epithermal mineralization. A hierarchical remote sensing forecast and prospecting model of epithermal Au/Ag deposits is proposed.
