Abstract
The article is devoted to the implementation of the methodology for paleovolcanic structure analyzing using 3D visualization of the model of the geological territory structure based on the relief digital model. The approach used made it possible to identify two paleovolcanic apparatuses and their structural elements: cone fragments, explosive domes, porphyritic stocks, ring fault zones with localization of dike belts in them. This, within the framework of the evolution model of porphyry ore systems, made it possible to identify promising areas for prospecting on ore objects of a given type. The procedure was checked on the basis of geochemical survey results. The regular control by the selected structural elements of geochemical fields was shown. The analysis of the spatial position of the selected structural blocks with a certain geochemical characteristic rather well into the evolution model of the porphyry ore systems. In all cases the control of geochemical halos by porphyry stocks is noted, the material rock complexes that are fragments of the zonal stone hat of the porphyry ore object, are quite clearly distinguished. Within the area of work, three ore-magmatic systems can be identified at a low level of erosion shear, potentially accompanied by porphyry-type ore mineralization.
