Volcanic igneous environments
Luetheite is a rare mineral filling cavities in intensely altered volcanic rock
At the type locality, the Humboldt Mine area, Harshaw Mining District, Patagonia Mountains, Santa Cruz county, Arizona, USA, luetheite occurs as as minute crystals in silicified rhyolite porphyry with chenevixite, cornubite and hematite (AM 62.1058, HOM).
At the Majuba Hill Mine, Antelope Mining District, Pershing county, Nevada, USA, luetheite occurs in the oxidised zone of a copper deposit, associated with pharmacosiderite, arthurite, scorodite, chenevixite and zeunerite (HOM).
