Plagioclase size distributions of the 2001 Etnean products. The CSDs are summations for samples from each of the three eruptive vents. The increase in the total number of crystals increased the number of crystals that populate the largest size classes
Crystal size distributions of plagioclase in lavas from the July–August 2001 Mount Etna eruption
Fig. 4. Downflow output obtained on the western flank of Mt Etna from the subterminal vent opened at 3050 m above sea level in 2006 to the west of the Southeast Crater.
Simulating the area covered by lava flows using the DOWNFLOW code
Photographs of comenditic trachyte enclaves from the Randazzo pumice cone and Khaggiar lava flow. (a): fresh‐cut surfaces of a block showing the porphyritic texture of the enclaves given by abundant large crystals of anorthoclase embedded in a gray matrix. Subspherical vesicles are dispersed in the enclaves. (b): the typical globular external margin of the enclaves. (c): block cut perpendicular to the surface showing undulate margins with deep indents (d): small enclaves (light gray with feldspar phenocrysts) dispersed in the Khaggiar lava. (e): enclaves in the Khaggiar lava characterized by a crenulated surface, porphyritic texture and subspherical vesicles
Cooling and crystallization recorded in trachytic enclaves hosted in pantelleritic magmas (Pantelleria, Italy): Implications for pantellerite petrogenesis
Results from the sensitivity study. In the top panels the model outputs for the total crystal content at the vent are shown, while in the bottom panels the model outputs of mass discharge rate at the vent are illustrated. Panels (a) and (d) report the mass discharge rate and the crystal content at a fixed water content (3.0 wt%), in panels (b) and (e) the conduit radius has been fixed (0.7 m), while panels (c) and (f) illustrate the data at a given temperature (1363 K)
