A study of volcanogenic exhalation mineralization

This paper considers volcanogenic exhalation mineralization using data from 35 years of observation of fumarole activity during an earlier phase of the posteruptive activity of the Second Cone, which is one of the New Tolbachik volcanoes that were formed during the eruption at the North Vent of the Great Tolbachik Fissure Eruption (Kamchatka, 1975–1976). We describe the main types of mineral associations, identify the key mineral species and the secondary and accessory minerals, as well as the sequence of mineral generation. We provide a summary of minerals and compounds that have been identified in ejecta of fumaroles on the Second Cone.
