About the Genesis of Pumice Deposits in the Region of Tarbagania and Pemzovaya Mountains in Kamchatka

This paper discusses the results of study of pumice deposits between volcanoes Gorely and Mutnovskiy on Kamchatka. A scheme of the pumice sheets is presented. The results of petrochemical and geochemical studies of pumice and acidic lavas of Mutnovsky and Gorely are discussed. A number of petrogeoch...

Description
Summary:This paper discusses the results of study of pumice deposits between volcanoes Gorely and Mutnovskiy on Kamchatka. A scheme of the pumice sheets is presented. The results of petrochemical and geochemical studies of pumice and acidic lavas of Mutnovsky and Gorely are discussed. A number of petrogeochemical pumice features indicating their possible genetic isolation is revealed. В работе обсуждаются результаты изучения пемзовых отложений, расположенных в промежутке между вулканами Горелый и Мутновский на Камчатке. Приведены схема распространения пемзовых покровов и результаты петрохимических и геохимических исследований пемз и кислых лав. Выявлен ряд петрогеохимических особенностей пемз, указывающих на их вероятную генетическую обособленность.
