Andesitic volcanism and crustal evolution
Eichelberger JC. 1978. Andesitic volcanism and crustal evolution. Nature. 275(5675):21-27
Petrological evidence indicates that andesite is a mixture of melts from the upper mantle and lower crust. Mixing is favoured by a compressional environment and generation of rhyolitic crustal melt is favoured by continental crust. Andesitic volcanism apparently involves both addition of new material to the crust and fractionation of pre-existing crust.
