'''Tyrolite''' is a [[hydrate|hydrous]] [[calcium]] [[copper]] [[arsenate mineral|arsenate]] [[carbonate mineral]] with the [[chemical formula|formula]] [[calcium|Ca]][[copper|Cu]]<sub>5</sub>([[arsenic|As]][[oxygen|O]]<sub>4</sub>)<sub>2</sub>[[carbon|C]]O<sub>3</sub>(O[[hydrogen|H]])<sub>4</sub>⋅6[[water|H<sub>2</sub>O]]. Tyrolite forms glassy, blue to green [[orthorhombic crystal system|orthorhombic]] radial crystals and [[botryoidal]] masses. It has a [[Mohs hardness]] of 1.5–2.0 and a [[relative density|specific gravity]] of 3.1–3.2. It is [[transparency and translucency|translucent]] with [[refractive index|refractive indices]] 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]], [[county of Tyrol|Tyrol]], [[Austria]].
