Abstract
This is the first petrophysical study of extrusive rocks (dacites to andesites) discharged by Bezymianny Volcano. We provide a comparative description of properties for extrusive rocks in accordance with identified age groups. We show the dynamics in the variation of extrusive rock properties in relation to their ages, with the result that the older a rock the higher are its density, strength, and elastic parameters. Rocks petrophysical features are compared between extrusive domes and lava flows. We argue for petrophysical properties to be applicable for deriving more accurate results for the genesis of rocks having similar petrophysical properties, in particular, rocks of extrusive and effusive origin.
期刊介绍：
Journal of Volcanology and Seismology publishes theoretical and experimental studies, communications, and reports on volcanic, seismic, geodynamic, and magmatic processes occurring in the areas of island arcs and other active regions of the Earth. In particular, the journal looks at present-day land and submarine volcanic activity; Neogene–Quaternary volcanism; mechanisms of plutonic activity; the geochemistry of volcanic and postvolcanic processes; geothermal systems in volcanic regions; and seismological monitoring. In addition, the journal surveys earthquakes, volcanic eruptions, and techniques for predicting them.
