Metaconglomerate | Texture: Non-foliated Metamorphic Intensity: Intermediate to high Metamorphic Change: Recrystallization, rotation Characteristic Features: Parent rock - conglomerate; clast boundaries are fused; some minerals grains can be stretched and rotated |
Phyllite | Texture: Foliated Metamorphic Intensity: Low to intermediate Metamorphic Change: Recrystallization Characteristic Features: Satiny sheen, some samples have small micas present |
Mica Schist | Texture: Foliated Metamorphic Intensity: Intermediate Metamorphic Change: Recrystallization Characteristic Features: Prominent biotite and muscovite minerals |
Chlorite Schist | Texture: Foliated Metamorphic Intensity: Intermediate Metamorphic Change: Recrystallization Characteristic Features: Prominent chlorite minerals (greenish mica) |
Gneiss | Texture: Foliated Metamorphic Intensity: High Metamorphic Change: Recrystallization, Rotation Characteristic Features: Pronounced banding with the separation of light and dark minerals |
Garnets in Schist | Texture: Foliated Metamorphic Intensity: Intermediate Metamorphic Change: Recrystallization Characteristic Features: Dodecahedral garnet crystals within a mica schist |
Slate | Texture: Foliated Metamorphic Intensity: Low Metamorphic Change: Recrystallization Characteristic Features: Slatey cleavage, powders to a lighter color when scratched with a nail; rings when tapped with a nail |
