| ⓘ Albite Formula: Na(AlSi3O8) Colour: white Reference: Harold Moritz collection |
| ⓘ Almandine Formula: Fe2+3Al2(SiO4)3 Colour: maroon Description: small, poorly-formed crystals encrusted with mica. Reference: Harold Moritz collection |
| ⓘ Annite Formula: KFe2+3(AlSi3O10)(OH)2 Habit: flaky grains Colour: black Reference: Harold Moritz collection |

| ⓘ Kyanite Formula: Al2(SiO4)O Habit: elongated blades Colour: blue Description: Typical elongated blades to 4 cm, usually in quartz boudins. Crystals in schist may be replaced by fine-grained muscovite (damourite). Reference: Harold Moritz collection |
| ⓘ Muscovite Formula: KAl2(AlSi3O10)(OH)2 Habit: micaceous, compact Colour: silvery to pale green Description: Mostly as flaky grains, but may replace kyanite as very fine-grained, compact damourite. Reference: Harold Moritz collection |
| ⓘ Quartz Formula: SiO2 Habit: massive, anhedral grains Colour: colorless to pale smoky Description: As anhedral grains and concentrated in boudins that may host kyanite. Reference: Harold Moritz collection |
| ⓘ Schorl Formula: NaFe2+3Al6(Si6O18)(BO3)3(OH)3(OH) Habit: elongated prismatic Colour: black Description: Very small subhedral elongated prismatic crystals. Reference: Harold Moritz collection |
