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.
