Green Aventurine and Clear Quartz

Green Aventurine (Silicon Dioxide - SiO2 with Fuchsite inclusions); Clear Quartz (Silicon Dioxide - SiO2)

Hematite

Hematite (Fe2O3)

Micaceous Sandstone or Quartzite

Sandstone (lithified quartz grains, often with mica) or Quartzite (metamorphosed sandstone)

Granite Pebble

Granite (a plutonic igneous rock composed primarily of quartz, feldspar, and mica/amphibole)

Quartz

Quartz (Silicon Dioxide - SiO2)

Fluorite

Fluorite (Calcium Fluoride, CaF2)

Pebble (likely Quartzite or Chert)

Clastic Sediment, potentially composed of SiO₂ (Quartz)

Granite

Granite (a common type of Felsic Intrusive Igneous Rock)

Unknown Organic Object (likely a berry or fruit)

Not applicable; this is not a geological specimen. If it were a cranberry, its scientific name would be Vaccinium macrocarpon; if a cherry, it would be Prunus avium or Prunus cerasus.

Quartz (likely Jasper or Chert variety)

Quartz (SiO₂)

Shale with Vein Infillings

Shale (a fine-grained clastic sedimentary rock). The veins could be Calcite (CaCO3), Quartz (SiO2), or other minerals.

Mica (likely Muscovite)

Muscovite / KAl2(AlSi3O10)(OH)2

Chert (Flint)

Chert (predominantly SiO₂ - silicon dioxide)

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).

Soapstone

Steatite (primarily composed of Talc, Mg₃Si₄O₁₀(OH)₂)

Jade

There are two distinct minerals classified as Jade: Jadeite (Na(Al,Fe3+)Si2O6) and Nephrite (Ca2(Mg,Fe)5Si8O22(OH)2). Based on the image showing translucent, somewhat fibrous material, it is likely Nephrite.

Banded Chert

Chert (a microcrystalline variety of quartz, SiO2 with minor impurities)

Jasper (likely a variety of Brecciated Jasper or a patterned variety)

Silicon dioxide (SiO2)

Granite (weathered/river-tumbled)

Granite (Plutonic Igneous Rock)

Muscovite Mica

Muscovite (Potassium Mica) KAl2(AlSi3O10)(OH)2

Fuchsite Quartzite

Silicon Dioxide (SiO2) with iron inclusions

Serpentine

Serpentinite (rock), Serpentine group minerals (e.g., Antigorite, Lizardite, Chrysotile)

Red Jasper

Jasper (a variety of Chalcedony, SiO₂ with iron oxide inclusions)

Conglomerate (Puddingstone)

Conglomerate (specifically, clastic sedimentary rock)

Granite

Granite (a felsic intrusive igneous rock)

Calcite

Calcite (Mineral; CaCO₃)

Fluorite

Fluorite (Calcium Fluoride - CaF2)

Petrified Wood

Silicified wood, primarily composed of Quartz (SiO2)

Pebble or Cobble (likely composed of sandstone or conglomerate)

Clastic Sedimentary Rock (specific name like sandstone, conglomerate, or breccia would require microscopic analysis of clast size and angularity)

Shale

Shale (fine-grained clastic sedimentary rock)

River Cobble (likely Sandstone or Siltstone type)

Sandstone or Siltstone (common rock types that form river cobbles)

Conglomerate

Conglomerate

Sandstone (likely a river or beach pebble)

Sandstone (a clastic sedimentary rock)

Sodalite (Sodium Aluminum Silicate Chloride), Na8(Al6Si6O24)Cl2

Marble

Metamorphosed Limestone/Dolomite

Sapphire (likely blue synthetic sapphire or blue glass in a ring)

Corundum (Al₂O₃), specifically the blue variety due to trace amounts of iron and titanium impurities. If synthetic, it would still be Al₂O₃.

Travertine (used in construction, not a 'specimen' in situ)

Travertine

Chert (varieties include Flint or Jasper)

Chert (cryptocrystalline quartz; SiO₂)
