«Гидротермы активных вулканов Южной Камчатки и Курил: геохимия, структура транспорта, генезис»
Докладчик: д.г.-м.н. Светлана Борисовна Бортникова
Коллектив авторов: Гора М.П., Шевко А.Я., Панин Г.Л., Манштейн Ю.А., Манштейн А.К., Бессонова Е.П., Белобородов В.А., Бортникова С.П., Карин Ю.Г., Ельцов И.Н., Присекина Н.А.
На основе многолетних исследований термальных источников на активных вулканах Курило-Камчатского региона определена высокая контрастность составов растворов как по физико-химическим параметрам, так и по концентрациям основных и примесных элементов. Анализ взаимодействия «гидротермальный раствор – вмещающая порода» свидетельствует о сложном многоступенчатом процессе извлечения химических элементов из пород разреза, неоднократном концентрировании некоторых из них и повторном вовлечении в гидротермальный транспорт обогащенных фаций метасоматитов. Геофизические исследования подповерхностного пространства термальных полей позволили выявить их внутреннюю структуру: строение подводящих каналов; зональность среды, обусловленную закономерным распределением гидротермальных растворов с разными параметрами; наличие приповерхностных барьеров, ответственных за фазовое разделение поднимающихся растворов. Объяснение появления аномальных концентраций некоторых химических элементов в растворах термальных источников получено с помощью численного моделирования, которое показало разные пути движения элементов от магматической камеры до поверхности. Проведенное комплексное исследование активных вулканов позволяет построение адекватной модели функционирования вулкано-гидротермальной системы и проливает свет на генезис многих химических элементов, концентрирующихся в разных частях разреза.
