Pseudo-amphibolites in the Southern Amphibolite Belt, Kohistan Arc, N. Pakistan
Abstract
More evidences strengthening the View of the existence of (a) pseudoamphibolite forming as a result of reaction between pre-gran hornblendite or amphibolite and the granitic magma and (b) of certain hornblendites forming as a result of reaction between pre-granitic amphibolite and the granitic magma, in the southern amphibolite belt of the Kohistan island arc, are presented in this paper.
