Coexisting orthoalnphiboles (high Al-Na gedrites and low Al-Na anthophyllites) from the Post Pond Volcanics, Vermont, display a variety of textures that are interpreted to be equilibrium growth textures. These textures include: (l) discrete grains; (2) bladed intergrowths; (3) patchy intergrowths; (4) overgrofihs; and (5) lamellar intergrowths with lamellae parallel to (120). Coexisting orthoamphiboles display exsolution parallel to (010); exsolution is much more pronounced in gedrite than in… CONTINUE READING
