The Conditions of Opal Formation within the NorthMutnovskaya Volcanic Zone of Kamchatka

The characteristics of formation of the opal mineralization in the host rock within Mutnovskaya volcanic zone were studied. The type of metasomatic rock alteration and its consecutive order were established. The results of study allowed identifying the mineral inclusions in opals, which was linked t...

Description
Summary:The characteristics of formation of the opal mineralization in the host rock within Mutnovskaya volcanic zone were studied. The type of metasomatic rock alteration and its consecutive order were established. The results of study allowed identifying the mineral inclusions in opals, which was linked to the metalliferousness of the Mutnovsky hydrothermal system. Probable mechanism of opals formation within the North Mutnovskaya zone is considered, and its characteristics are compared to those from the opal field Raduzhnoye, Primorye. Выявлены параметры образования вмещающих пород опаловой минерализации. Установлены тип метасоматоза измененных пород и его направленность. Выявлены минеральные включения в опалах, указывающие на металлоносность Мутновской гидротермальной системы. Рассмотрен вероятный механизм образования опалов Северо-Мутновской зоны, проведено сопоставление по ряду характеристик с опалами месторождения Радужное, Приморье.
