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.
Rhyolitic magmas have lower temperatures. All are above 573Â° and below 870Â°. Nearly all are below the temperature of decomposition of biotite, about 850Â°, and that of common hornblende, about 750Â°. Probably most rhyolitic magmas have temperatures in the neighborhood of 600Â° to 700Â°.
