Gneiss containing SiO2 (Quartz) intrusion

Wishing Stone (Veined Pebble)

Quartz-veined Metasedimentary Pebble

Quartz-bearing altered rock, possibly iron-stained quartz vein

Quartz (SiO₂) in a feldspathic/sericitized host, with iron-oxide staining

Quartz Vein in Host Rock

Silicon dioxide (SiO2) veining in silicate matrix

Conglomerate

Conglomerate (clastic sedimentary rock type)

Conglomerate

Pebble Conglomerate / Clastic Sedimentary Rock

Quartz Vein in Sedimentary Matrix

Silicon Dioxide (SiO2) with host rock

Iron-rich breccia

Hematite–goethite-rich ferruginous breccia, likely a lateritic ironstone

Metaconglomerate

Metaconglomerate (Quartzite conglomerate)

Conglomerate

Conglomerate (Sedimentary rock containing rounded clasts)

Conglomerate

Conglomerate

Wishing Stone (Basalt/Greywacke with Quartz Vein)

Basalt or Siltstone with SiO2 (Quartz) hydrothermal intrusion

Concrete

Anthropogenic Conglomerate

Conglomerate

Conglomerate

Siltstone with Quartz Vein

Siltstone (primarily SiO2, Al2O3, Fe2O3)

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.

Conglomerate

Conglomerate (SiO2 matrix with various lithic clasts)

Light-colored quartz-rich stone, possibly milky quartz

Quartz (SiO₂), provisional identification

Iron sulfide-rich ore, possibly pyrite-bearing gossan

Likely pyrite (FeS₂) with iron oxides/hydroxides and host rock; exact identification requires testing

Puddingstone

Conglomerate (Gowganda Formation)

Conglomerate (Red Sandstone variety)

Clastic Sedimentary Rock (Conglomeratic Sandstone)

Granitic Pegmatite Intrusion in Host Rock

Pegmatite dike in amphibolite or schist

Quartz Pebble

Silicon Dioxide (SiO2)

Basalt with Quartz/Calcite Vein

Amygdaloidal Basalt (matrix) with Mineral Vein filling

Jasper Breccia

Silicon Dioxide (SiO2) with impurities

Jasper Agate (specifically Brecciated Jasper)

Silicon Dioxide (SiO2) with iron oxide and clay impurities

Puddingstone (Gowganda)

Gowganda Formation Conglomerate

River Pebble (Siltstone / Fine-grained Sandstone)

Sedimentary Pebble (Siliclastic)

Quartz Pebble

Silicon dioxide (SiO2)

Vesicular quartz-rich rock, possibly weathered rhyolite or silicified volcanic breccia

Silica-rich volcanic rock; likely microcrystalline quartz (SiO₂) with altered feldspar and iron-oxide staining

Puddingstone

Conglomerate (Jasper Conglomerate)

Quartz (milky quartz), possibly calcite

Quartz: SiO₂; visual identification is uncertain because the specimen is wet and lacks diagnostic crystal faces

Quartz Vein in Host Rock

Crystalline Silicon Dioxide (SiO2) in Pelitic or Shaly Matrix

Sandstone with Quartz Vein

Arenite with Crystalline Silica (SiO2)

Sandstone and Conglomerate pebbles

Sedimentary clastic rock

River Pebble (likely Quartzite or Chert)
