Pegmatite (Granitic)

Granitic Pegmatite containing Quartz, Feldspar, and Tourmaline (Schorl)

Limestone

Calcium Carbonate (CaCO3)

Sandstone

Arenite (composed primarily of SiO2)

Black Onyx

Black Chalcedony (SiO2)

Coquina

Coquina (a type of limestone)

Crushed Limestone (Gravel)

Calcium Carbonate (CaCO3)

Sandstone (likely Quartzose)

Arenite (primarily SiO2)

Amber

Succinite (fossilized resin, C10H16O)

Turquoise

Pebble (likely Quartz or Chert)

SiO₂ (Silicon Dioxide) - referring to the likely main mineral composition, Quartz. If it's chert, the scientific name remains SiO₂ with a microcrystalline structure.

Ferruginous Sandstone

Sandstone, Iron-rich

Chert (Flint)

Chert (SiO2)

Asphalt (Bituminous Concrete)

Composite material (bitumen binder with mineral aggregate)

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.
