Anamorphic schists are often found most closely blended with hornblende

a significant sounding phrase, used in some lectures with no particular meaning Anamorphic means having to do with the deformation and change in rocks from great pressure and heat deep below the earth's surface. A schist is any metamorphic (characterized by change in the composition of rocks under pressure, heat, chemical action, etc.) rock of a type that splits easily into thin leaves. Hornblende is a darkgreen to black mineral.
