Metamorphic Rock (Specifically A Rock Composed Of Minerals)

Gneiss

Gneissic Metamorphic Rock

Gneiss (specifically Granite Gneiss)

Gneiss (High-grade Regional Metamorphic Rock)

Granite Gneiss

Gneiss (High-grade Metamorphic Rock)

Gneiss

Gneiss (high-grade metamorphic rock)

Dalmatian Stone (Dalmatian Jasper)

Peralkaline Quartz-Feldspar Porphyry with Arfvedsonite

Banded Gneiss (Variety of Gneiss)

Gneiss (specifically, a variety exhibiting prominent banding; mineral composition can vary, but often contains quartz, feldspar, mica, and amphibole)

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.
