Mineral Based Human Made Alloy

Basalt

Vesicular Basalt (Mafic volcanic rock)

Serpentine

Serpentinite (a rock composed primarily of serpentine minerals like antigorite, chrysotile, and lizardite; general formula (Mg, Fe)3Si2O5(OH)4)

Basalt (Weathered Pebble)

Extrusive mafic igneous rock; minerals primarily Plagioclase feldspar and Pyroxene

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.

Mahogany Obsidian or Red Jasper

Silicon Dioxide with Iron Oxide (SiO2+Fe2O3)

Basalt

Mafic Volcanic Rock (composed of Plagioclase Feldspar and Pyroxene)

Beryl (Variety Mix)

Be3Al2(Si6O18)

Breccia

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

Basalt

Basalt (Aphanitic Mafic Volcanic Rock)

Soapstone

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

Lapis Lazuli

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

Basalt (Vesicular)

Vesicular Basalt

Mica Schist

Mica Schist (Composition typically includes Muscovite KAl2(AlSi3O10)(OH)2 and Quartz SiO2)

Granite

Granite (Felsic Plutonic Rock)

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)

Chalcedony

Chalcedony (a microcrystalline variety of Quartz, SiO2)

Muscovite Mica

Muscovite (KAl2(AlSi3O10)(OH)2)

Sandstone (likely a river or beach pebble)

Sandstone (a clastic sedimentary rock)

Granite

Granite (a plutonic igneous rock)

Green Apophyllite and Stilbite on Quartz Cluster

Apophyllite-(K) (KCa4(Si8O20)(F,OH)·8H2O), Stilbite-Ca (NaCa4(Si27Al9)O72·28H2O), Quartz (SiO2)

Limonite (Iron-rich Siltstone / Sandstone base)

Hydrous ferric oxide mixture (FeO(OH)·nH2O)

Porphyry

Porphyritic Andesite/Basalt

Dendritic Agate (or Dendritic Opal)

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

Diorite

Diorite (Intermediate intrusive 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.

Black Chert

Chert (microcrystalline quartz)

Basalt

Extrusive Mafic Igneous Rock (composed primarily of plagioclase feldspar and pyroxene)

Iron Slag

Vitreous glassy waste (Fe-Si-Al-Ca compounds)

Titanium Coated Aura Quartz (Apple Aura Quartz)

K2 Jasper (Beads)

Granodiorite with Azurite and Malachite

Jade (Nephrite or Jadeite)

Nephrite (Ca2(Mg,Fe)5Si8O22(OH)2) or Jadeite (Na(Al,Fe3+)Si2O6)

Granite

Granite (a felsic intrusive igneous rock)

Basalt

Basalt (Igneous Volcanic Rock)

Laterite

Laterite (no specific mineral formula as it's a rock type)

Quartz

Silicon dioxide (SiO₂)

Fossilized Shark Tooth (Basal Bone)

Otodus sp. (Mineralized Hydroxyapatite)

Stiped Slate Beach Pebble

Low-grade Metamorphic Slate with Quartz Vein (SiO2 on Phyllosilicate base)
