Thallium minerals

Avicennite (thallium(III) oxide) is an oxide mineral. It was discovered around the Dzhuzumli village, Samarqand, Uzbekistan. It is named after Avicenna, a Persian doctor and polymath.

Hutchinsonite is a sulfosalt mineral of thallium, arsenic and lead with formula . Hutchinsonite is a rare hydrothermal mineral.

Lorándite is a thallium arsenic sulfosalt with the chemical formula: TlAsS2. Though rare, it is the most common thallium-bearing mineral. Lorándite occurs in low-temperature hydrothermal associations and in gold and mercury ore deposits. Associated minerals include stibnite, realgar, orpiment, cinnabar, vrbaite, greigite, marcasite, pyrite, tetrahedrite, antimonian sphalerite, arsenic and barite.

Cuprostibite  (the name is formed from the addition of two words: cuprum and stibium) — a very rare polymetallic mineral of the sulfide class, consisting of mixed copper and thallium stibnite (although not in all samples), sometimes with admixtures of tin and other metals, ideal formula Cu2(Sb,Tl) or Cu2Sb. The mineral is opaque, it has a metallic luster and a beautiful color from steel gray to violet-pink when freshly chipped.

Crookesite is a selenide mineral composed of copper and selenium with variable thallium and silver.

Christite is a mineral with the chemical formula TlHgAsS3. It is named after Dr. Charles L. Christ, a member of the U.S. Geological Survey. It usually comes in a crimson red or bright orange color. It has a density of 6.2 and has a rating between 1 and 2 on Mohs Hardness Scale. Christite has an adamantine luster and leaves behind an orange streak. Its crystal system is monoclinic with possible crystal classes of twofold symmetry, mirror plane symmetry, and twofold with a mirror plane. This means it can have radial symmetry, mirror plane symmetry, or mirror plane symmetry perpendicular to the t

Galkhaite is a rare and chemically complex sulfosalt mineral from a group of natural thioarsenites. Its formula is , making the mineral the only known natural Cs-Hg and Cs-As phase. It occurs in Carlin-type hydrothermal deposits.

Routhierite is a rare thallium sulfosalt mineral with formula .

Sabatierite (Cu6TlSe4) is a mineral found in the Czech Republic. The composition of the mineral is more likely (Cu4TlSe3) that has been chemically and crystalographically characterized having tetragonal symmetry. It is named for the French mineralogist Germain Sabatier (born 1923).

Bukovite is a rare selenide mineral with formula Tl2Cu3FeSe4. It is a brown to black metallic mineral which crystallizes in the tetragonal system.

Enneasartorite is a very rare mineral with formula Tl6Pb32As70S140. It belongs to sartorite homologous series. It is related to other recently approved minerals of the sartorite series: hendekasartorite and heptasartorite. All come from Lengenbach quarry in Switzerland, which is famous for thallium sulfosalts. Enneasartorite is chemically similar to edenharterite and hutchinsonite.

Hendekasartorite is a very rare thallium sulfosalt mineral with formula Tl2Pb48As82S172. It is one of recently approved new members of sartorite homologous series, by enneasartorite and heptasartorite. All new members come from Lengenbach quarry in Switzerland, prolific in terms of thallium sulfosalt minerals. Hendekasartorite is chemically similar to edenharterite and hutchinsonite.

Fangite is a sulfosalt first discovered in the Mercur gold deposit located in Tooele County Utah. The specimen was found in a boulder in the southern Oquirrh Mountains. The only available specimens of fangite are located in the National Museum of Natural History, Smithsonian Institution. The International Mineralogical Association Commission approved the name Fangite after Dr. Jen-Ho Fang, a crystal chemist affiliated with the University of Alabama, in honor of his significant contributions to crystallography, crystal chemistry, and geostatistics.

Rayite, a monoclinic mineral containing Lead-Silver-Thallium-Antimony, was found during microscopic and electron microprobe study of specimens from the complex, polymetallic sulphide-native metal sulpho-salt paragenesis of Rajpura-Dariba, Rajasthan, India. It is named after Dr. Santosh K. Ray of President College, Calcutta, India. It bears a striking resemblance to owyheeite in terms of its Lead/(Silver,Thallium)/Antimony ratio, yet its structural affinity lies with Semseyite. The average composition is Lead-47.06, Copper-0.03, Silver-4.54, Thallium-2.04, Antimony-27.42, Sulphur-19.59 by wt.%

Heptasartorite is a very rare mineral with formula Tl7Pb22As55S108. It belongs to sartorite homologous series. It is related to other recently approved minerals of the series: enneasartorite and hendekasartorite. All three minerals come from a quarry in Lengenbach, Switzerland, which is famous of thallium minerals. Chemically similar minerals include edenharterite and hutchinsonite.

Gabrielite is an extremely rare thallium sulfosalt mineral with a chemical formula of or .
