摘 要:正The formation and transport of basaltic magma in the mantle by adiabatic decompression can be characterized in terms of the velocity of the upwelling (solid) mantle, the rate of melting, the melt velocity, the dispersivity associated with melt migration, and the delay time, or storage time, of magma before eruption. Two of these parameters, the velocity of upwelling mantle and the corresponding melting rate, can be estimated from models coupled with thermodynamic data and
