Organic minerals

Anthracite is a hard, compact variety of coal that has a submetallic luster.

Abelsonite is a nickel porphyrin mineral with chemical formula C31H32N4Ni.

Lignite, often referred to as brown coal, is a soft brown combustible sedimentary rock formed from naturally compressed peat.

Evenkite is a rare hydrocarbon mineral with formula (CH3)2(CH2)22 or C24H50.

Guanine /ˈɡwɑːnᵻn/ (G, Gua) is one of the four main nucleobases found in the nucleic acids DNA and RNA, the others being adenine, cytosine, and thymine (uracil in RNA).

Earlandite (Ca3(C6H5O7)2·4H2O) is the mineral form of calcium citrate tetrahydrate.

Chanabayaite is the first recognized triazolate mineral, having the following formula: Cu2(N3C2H2Cl(NH3,Cl,H2O,[])4. Minor iron admixture is also present. It is also one of a few currently known minerals containing ammine groups, including also ammineite, joanneumite and shilovite. All the minerals are rare and were found in a single guano deposit in Chile, called Pabellón de Pica. A similar natural phase, formula NaCu2Cl3[N3C2H2]2[NH3]2·4H2O, likely a precursor of chanabayaite, is described by Zubkova et al. 2016.

Joanneumite is the first recognized isocyanurate mineral, with the formula Cu(C3N3O3H2)2(NH3)2.

Wampenite is a rare organic mineral with the formula C18H16, found in Wampen, Fichtelgebirge, Bavaria, Germany.

Kratochvilite is a rare organic mineral formed by combustion of coal or pyritic black shale deposits.

Carpathite (also pendletonite and karpatite) is a very rare hydrocarbon mineral.

Hoelite is a mineral, discovered in 1922 at Mt.

Mellite, also called honeystone, is an unusual mineral being also an organic chemical.

Fichtelite is a rare white mineral found in fossilized wood from Bavaria.

Simonellite (1,1-dimethyl-1,2,3,4-tetrahydro-7-isopropyl phenanthrene) is a polycyclic aromatic hydrocarbon with a chemical formula C19H24.

Uricite is a rare organic mineral form of uric acid, C5H4N4O3.

Idrialite, or idrialine, is a soft, orthorhombic hydrocarbon mineral with chemical formula: C22H14.
