'''Tyrolite''' is a [hydrous](/source/hydrate) [calcium](/source/calcium) [copper](/source/copper) [arsenate](/source/arsenate_mineral) [carbonate mineral](/source/carbonate_mineral) with the [formula](/source/chemical_formula) [Ca](/source/calcium)[Cu](/source/copper)<sub>5</sub>([As](/source/arsenic)[O](/source/oxygen)<sub>4</sub>)<sub>2</sub>[C](/source/carbon)O<sub>3</sub>(O[H](/source/hydrogen))<sub>4</sub>⋅6[H<sub>2</sub>O](/source/water). Tyrolite forms glassy, blue to green [orthorhombic](/source/orthorhombic_crystal_system) radial crystals and [botryoidal](/source/botryoidal) masses. It has a [Mohs hardness](/source/Mohs_hardness) of 1.5–2.0 and a [specific gravity](/source/relative_density) of 3.1–3.2. It is [translucent](/source/transparency_and_translucency) with [refractive indices](/source/refractive_index) of ''n''α&nbsp;=&nbsp;1.694, ''n''β&nbsp;=&nbsp;1.726, and ''n''γ&nbsp;=&nbsp;1.730.

It is a secondary mineral formed by the weathering of associated copper and arsenic minerals. It was first described in 1845 for an occurrence in [Schwaz](/source/Schwaz), [Tyrol](/source/county_of_Tyrol), [Austria](/source/Austria).
