Использованный подход позволил выделить два палеовулканических аппарата и слагающие их структурные элементы: фрагменты конуса, эксплозивные купола, штоки порфиритов, зоны кольцевых разломов с локализацией в них дайковых поясов. Это, в рамках модели эволюции порфировых рудных систем, дало возможность выделить перспективные площади для постановки поисковых работ на рудные объекты заданного типа. Проверка методики выполнена на основании результатов геохимической съемки. Был показан закономерный контроль выделенными структурными элементами геохимических полей. Анализ пространственного положения выделенных структурных блоков с определенной геохимической характеристикой довольно хорошо укладывается в рамки модели эволюции порфировых рудных систем. Во всех случаях отмечается контроль порфировыми штоками геохимических ореолов, довольно ярко выделяются вещественные комплексы пород, являющиеся фрагментами зональной каменной «шляпы» порфирового рудного объекта. В пределах площади работ можно выделить три рудно-магматические системы на малом уровне эрозионного среза, потенциально сопровождающиеся рудной минерализацией порфирового типа.</p></abstract><trans-abstract xml:lang="en"><p>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.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>порфировые системы</kwd><kwd>трехмерные геологические модели</kwd><kwd>комплексные геохимические ореолы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>porphyry systems</kwd><kwd>three-dimensional geologic models</kwd><kwd>complex geochemical halos</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено в рамках выполнения государственного задания по Проекту IX.130.3.1 (№0284-2021-0001).</funding-statement><funding-statement xml:lang="en">The study was carried out as part of the state assignment for Project IX.130.3.1 (No. 0284-2021-0001).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Audétat A., Pettke T., Heinrich C.A., Bodnar R.J., 2008.
