Description :
Intense and selective stratabound albitization and amphibole alteration of a bedded unit, producing massive layers of albitite (white and pink) and amphibole (dark green) alteration resembling syenite and metamorphic amphibolite, respectively. As observed in A the earlier white albite (Ab1) is in part replaced by patches of pink (Ab2) albite. Veins of amphibole cut the albitite
