High-Viscosity Silicic Lavas (Rhyolite, Dacite, and Andesite)ountry rock assimilation, usually in crustal magma reservoirs, generate felsic magma bodies with progressively lower temperature, increasing silica content and higher viscosity. These in turn affect the mobility, flow distance of any erupted lava flow which generally decreases as the SiO. content an

Explosive Eruption Styles, Columns, and Pyroclastic Fallout Deposits produce pyroclastic fallout deposits. At the small-scale end of the spectrum of subaerial explosive eruptions, we include strombolian ., halema’ma’uan and small-scale vulcanian and hydrothermal explosions. At the next level, there are small-scale hawai’ian magma/fire fountaining and larger scale vu

Subaqueous Flows of Pyroclastic Debris and Their Depositssubaerial vents, or are erupted from subaqueous vents. Does dynamic interaction with the ambient water mass occur? Do the flows mix in ambient water, and transform from hot, gas-supported pyroclastic (mass) flows into water-supported mass flows (e.g. syn-eruptive debris flows and megaturbidity curre

Surface Sedimentary (Epiclastic) Processes and Deposits in Volcanic Environments8) have been marked by major-impact sedimentary events both during and immediately after their respective eruptions. These secondary events have produced at least as much damage to infrastructure as the primary eruption processes, and have led to numerous deaths. In the case of the Mt Pinatubo erupt

These processes include devitrification, palagonitisation (in mafic glass), hydrothermal alteration, diagenesis, metamorphism, and tectonic deformation, which may significantly modify and in some cases completely disguise original volcanic textures. The process that induces textural cha
