Fuchsite Schist with Quartz

Chromian Muscovite [K(Al,Cr)2(AlSi3O10)(OH)2] Schist

Basalt

Basalt (Aphanitic Mafic Igneous Rock)

Granodiorite

Granodiorite (phaneritic intrusive igneous rock)

Granite

Phaneritic Plutonic Rock (primarily Quartz, Feldspar, and Mica)

Basalt

Basalt (Aphanitic Mafic Volcanic Rock)

Diorite

Diorite (Intermediate intrusive igneous rock)

Weathered granite or granitic pegmatite cobble

Granite/granitic rock, composed mainly of quartz (SiO₂), feldspar, and minor biotite or other dark minerals; the reddish-brown areas may be iron-oxide staining or weathered accessory minerals

Basalt (Weathered Pebble)

Extrusive mafic igneous rock; minerals primarily Plagioclase feldspar and Pyroxene

Quartz with Mica Schist Matrix

Quartz (SiO2) in Mica Schist Matrix

Granite

Intrusive Phaneritic Felsic Igneous Rock

Granite

Granite (Felsic Plutonic Rock)

Basalt

Mafic Volcanic Rock (composed of Plagioclase Feldspar and Pyroxene)

Dark mafic rock, likely basalt

Basalt (fine-grained assemblage chiefly plagioclase and pyroxene, commonly with olivine and iron oxides)

Weathered basaltic volcanic rock

Likely vesicular basalt or basaltic-andesite; chiefly plagioclase, pyroxene, and iron-bearing minerals

Banded Metamorphic Rock (likely Quartzite or Serpentinite/Soapstone)

Metamorphic Rock (possibly a banded Quartzite or a foliated Serpentinite/Talc Schist based on appearance, general term for such a rock is 'Banded Metamorphic Rock' or 'Gneiss' if pronounced banding of different minerals)

Breccia

Clastic Breccia (General mineral composition depends on fragments, often SiO2 or CaCO3)

Basalt (Vesicular)

Vesicular Basalt

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.

Lapis Lazuli

Complex mixture of minerals, primarily Lazurite (Na,Ca)8(AlSiO4)6(S,Cl,SO4,OH)2

Topaz

Al2SiO4(F,OH)2

Mica Group Minerals

There isn't a single scientific name as 'Mica' refers to a group of phyllosilicate minerals. Common scientific names include Muscovite (KAl₂ (AlSi₃O₁₀)(OH)₂), Biotite (K(Mg,Fe)₃AlSi₃O₁₀(OH)₂), Phlogopite (KMg₃AlSi₃O₁₀(OH)₂), and Lepidolite (K(Li,Al)₃(Al,Si,Rb)₄O₁₀(F,OH)₂).

Granite

Granite (a plutonic igneous rock)

Jade

There are two distinct minerals commonly known as Jade: Nephrite (a calcium magnesium silicate - Ca2(Mg,Fe)5Si8O22(OH)2) and Jadeite (a sodium aluminum silicate - NaAlSi2O6). Based on the image showing a typically softer, more fibrous appearance, it is likely Nephrite.

Dendritic Agate (or Dendritic Opal)

SiO2 (for Agate), SiO2·nH2O (for Opal)

Fuchsite

Fuchsite (a variety of Muscovite mica, K(Al,Cr)2(AlSi3O10)(OH)2)
