Mineral In Metamorphic Rock

Serpentinite

Serpentinite (composed largely of serpentine group minerals including Antigorite, Lizardite, or Chrysotile)

Clear Quartz (Rock Crystal)

Silicon Dioxide (SiO2)

Clear Quartz (Rock Crystal)

Silicon Dioxide (SiO2)

Copper-bearing Mica Schist

Mica Schist with Native Copper inclusions

Mica Schist

Mica Schist (Complex Silicate Rock)

Pebble (likely a type of sandstone or quartzite pebble)

Clastic Sediment (specifically, a rudite-sized clast). If the pebble is composed of a specific rock type, its scientific name would be that rock type (e.g., 'Quartzite pebble', 'Granite pebble', 'Chert pebble'). Given its appearance, it is likely a metamorphic quartzite pebble or a hard sandstone pebble.
