摘要: [1] Samples of scoriae erupted at Stromboli volcano during its persistent strombolian activity were collected between 2005 and 2008. Chemical mineralogical compositions obtained on products from the three main crater sectors (SW, Central NE). Small chemical variations indicate a different degree evolution coupled with small difference magma temperature <10°C. Analysis acoustic data for same time period as scoria sampling, indicates that puffing (a overpressurized bubble degassing) was, average, mainly observed central craters times moved to NE sector. The cross-check two independent sets allowed us assess correlation composition vents. hotter are always vents where occurs indicating slightly higher can be expression an enhanced two-phase flow dynamics.
