Dynamics of Convective Heat and Mass Transfer in Permeable Parts of Seismofocal Zones of the Kamchatka Region and Conjugated Volcanic Arcs

Abstract

This chapter considers the dynamics of convective heating of mantle and crustal rocks in the seismic focal zone of Kamchatka region and associated volcanic arcs, which are characterized by the predominance of compressive stresses and the compaction of the heterophase medium. Features of heating, determining the dynamics of metasomatic transformations and convective melting, are studied on the basis of nonisothermal hydrodynamic model of heating of lithospheric rocks above the magmatic chambers.

Morphotectonic and petrological characteristics of Permo-Triassic traps of Siberia

“…This paper focuses on local data of structural control of trap magmatism in the SC Paleozoic platform cover and under the WSP Mesozoic cover obtained using GIS technologies [41][42][43] and supplemented by the analyses of the regional magmatism of SC and WSP, conducted in [34][35][36] and the forms of volcanic edifices and fractures of the earth's crust in the PTTS manifestation. Seismotomographic data visualization was carried out using an original data processing system GIS-ENDDB [43][44].…”
