IGNEOUS ORIGIN FOR THE Na IN THE CLOUD OF IO
نویسندگان
چکیده
We heated mixtures of sulfur and Na-bearing silicates in evacuated silica glass capsules to temperatures b tween 600øC and 950 ø C. At or above 850 ø C, Na-silicate glass reacts with elememal S to form a (Na, K) sulfide. Mobilization of this phase may account for the presence of Na and K on the surface of Io, and hence in the material sputtered into the Jovian magnetosphere.
