By Friday, THE FIRST DAY OF THE ACTUAL FESTIVAL, Woodstock Ventures was out of food. Then they had the gall to ask their confined neighbors for sandwich donations. About 750,000, if they didn't mind. Some locals felt so sorry for the hungry kids that they did what they could to help.
Basaltic magma is hotter, denser, and less viscous than most other  types of lava. It is poor in silica and rich in iron and magnesium.  Eruptions involving it are typically â¦ non explosive or only mildly  explosive.It is less dense, more viscous, and cooler than most other types of  magma. It usually has a very high gas content, meaning that most  eruptions involving it will be highly explosive. Most  supervolcanoes are fed by rhyolitic magma.
PHYSICAL PROPERTIES OF MAGMAS. Magma = Molten rock material, with or w/o crystals or other suspended solids. Â¥ May or may not contain dissolved gas phase (H2O or CO2) Â¥ Vesicles = Bubbles of gas formed in magma. Physical Properties of magma depend on: Â¥ Temperature Â¥ Density Â¥ Volatile Content Â¥ Viscosity All depend directly indirectly on composition. TEMPERATURE Basalt @ 1 atm: 1200-1250oC liquidus, 950-1000oC solidus. Rhyolite: Liquidus = 1050oC Hydrous solidus (with H2O) = 650 oC Anhydrous solidus (no H2O) = 750oC >> Rhyolite solidus defined as T where viscosity >1013 poise. >> Determined experimentally.
