Tirolite is a mineral that belongs to the arsenate class. Its chemical formula is Ca2CuAsO4OH, and it typically occurs as small green crystals. The correct spelling of this word is [ˈtɪrəlaɪt]. The phonetic transcription indicates that the stress is on the second syllable, and the vowels are pronounced as [ɪ], [ə], [aɪ], and [ɪ]. The spelling of the word derives from its place of discovery, Tirol, which is a region in the Austrian Alps. Tirolite is valued by collectors for its unique color and rarity.
Tirolite is a mineral that belongs to the arsenate mineral group. Its chemical formula is known as PbAl6(AsO4)4(OH)4·(H2O), with the presence of lead (Pb), aluminum (Al), arsenic (As), oxygen (O), and hydroxyl (OH) ions. It typically forms as small, prismatic crystals with a vitreous to adamantine luster. The color of tirolite ranges from yellow-green to emerald green.
Tirolite commonly occurs in oxidized lead and zinc ore deposits, where it forms as a secondary mineral through the reaction between water and primary ore minerals. It is often found in association with other arsenate minerals, such as mimetite, beudantite, and adamite.
The name "tirolite" is derived from the locality of its discovery, which is the Tirol province of Austria. It was first described in 1828 by German mineralogist Friedrich Wöhler.
Tirolite has no significant industrial or commercial applications due to its rarity and limited availability. However, it is highly valued among mineral collectors and enthusiasts for its vibrant green color and distinct crystal habit. Its crystalline form and color make it visually appealing and desirable for display purposes. Additionally, its association with other arsenate minerals in ore deposits contributes to its significance in mineralogical studies aimed at understanding geological processes and ore formation.
Copper-forth; a fine verdigris-green or azaure-blue carbonate of copper and arsenic.

The word "tirolite" is derived from the name of the region Tyrol in Austria, where the mineral was first discovered. The suffix "-ite" is commonly used in mineralogy to indicate a mineral or mineral species, hence "tirolite" refers to the mineral found in Tyrol.
