This book is the fi rst basic edition considering the issues of genetic volcanology. Petrological aspects of magma formation have been investigated as well as physical processes that account for the mechanisms of various types of eruptions. Continuous calc-alkaline series of the Klyuchevskoy volcano rocks (high-Mg basalts – high-Al basaltic andesites) have been shown to form due to decompression fractionation of dark-colored minerals taking place mostly between the eruptions during the pauses of magma migration. For the fi rst time a volcano has been presented as a wideband generator of periodic processes occurring within the intervals from a few seconds to a few days. To study the above processes, a unique large experimental facility representing a laboratory volcano was designed and constructed. Physical modelling carried out using this facility allowed developing a new classifi cation of gas-hydrodynamic regimes occurring in long vertical columns. Physical principles accounting for the monotonous and periodic types of eruptions of basalt and basaltic andesite volcanoes have been defi ned.
Dynamic model of the Klyuchevskoy volcano eruptions has been developed based upon the major aspects of basalt-basaltic andesite volcanism – magmatic melts evolution, periodicities in the eruption dynamics, and mechanisms of various types of eruptions.
For experts in geology, volcanology, petrology, mineralogy, geophysics, geothermal researches, oil geology, physics, gashydrodynamics, geography, and ecology.
