Possible role of amphibole in the origin of andesite. some experimental and natural evidence

Given the potential role of arc accretion and hence of island arc magmatism to continental crustal growth, the origin of andesite is an important problem that has created extensive debate. Evidence that supports a common, although not universal opinion amongst petrologists, that andesite is a differ...

Zusammenfassung:	Given the potential role of arc accretion and hence of island arc magmatism to continental crustal growth, the origin of andesite is an important problem that has created extensive debate. Evidence that supports a common, although not universal opinion amongst petrologists, that andesite is a differentiate of parental basaltic magmas is presented.
