Приведены результаты детальных геотермических и геохимических исследований в пределах участка. Представлен субширотный геологический и геотермический разрез участка по материалам бурения и каротажа. Статистический анализ материалов малоглубинной съемки участка площадью 6 км2 (более 1300 пунктов измерений температуры) позволил выделить участки выходов на поверхность минеральных вод с повышенной температурой и охарактеризовать тектонические особенности территории месторождения. Химический состав вод перспективен для бальнеологического использования.</p></abstract><trans-abstract xml:lang="en"><p>This article provides a geological, geophysical and geochemical description of the Dachnoye hydrothermal deposit (the central part of the Iturup Island, Kuril Islands), located in a zone of the modern tectonomagmatic activity. The results reported in the article describe the detailed thermal and geochemical studies within the deposit. This work presents the sublatitudinal geological and geothermal section of the deposit based on drilling and logging data. A statistical analysis of shallow-depth temperature survey of the deposit in an area of 6 km2 (over 1300 measurement points) allowed us to determine the sites where thermal mineral waters reach the surface and to characterize the tectonic features of the deposit area. Regarding the chemical composition of the waters, this area has a promising potential for balneological development.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>остров Итуруп</kwd><kwd>гидротермальное месторождение Дачное</kwd><kwd>термосъемка</kwd><kwd>статистический анализ</kwd><kwd>гидрохимия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Iturup Island</kwd><kwd>Dachnoye hydrothermal deposit</kwd><kwd>thermal survey</kwd><kwd>statistical analysis</kwd><kwd>hydrochemistry</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено при поддержке РФФИ в рамках госзадания ИМГиГ ДВО РАН (проект № 13-05-00544А, «Современная фумарольная и гидротермальная активность вулканов Южных Курильских островов»).</funding-statement><funding-statement xml:lang="en">The study was supported by the RFBR on the state assignment of the Institute of Marine Geology and Geophysics FEB RAS (project No. 13-05-00544A, "Modern fumarole and hydrothermal activity of volcanoes in the Southern Kuril Islands").</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">Байков В.А., Бакиров Н.К., Яковлев А.А., Математическая геология.
