Alabandite occurs in epithermal polymetallic sulphide veins and especially in low-temperature
(HOM). It is an accessory mineral in some enstatite chondrodites
(Dana). In hydrothermal veins it is commonly associated with galena,
calcite, rhodonite and
(HOM, R&M 86.6.530-535).
At Broken Hill, New South Wales, Australia, alabandite is associated with calcite, baryte, pyrite, chabazite and sulphur.
At the Uchacchacua mine, Lima Department, Peru, alabandite is associated with fluorite, proustite and rhodochrosite (R&M 86.6.530-535).
At the Sunnyside mine, San Juan County, Colorado, USA, alabandite is associated with friedelite and alleghanyite (R&M 86.6.530-535).
