Syngenite is an uncommon diagenetic component of marine salt deposits, a volcanic sublimate or pneumatolytic
reaction product, a hydrothermal vein filling in a geothermal field, or derived from bat guano in caves.
Associated minerals include halite and
arcanite in salt deposits, and
uricite, brushite and
gypsum in caves
At the type locality,the Kalusa salt deposit, Ivano-Frankivsk Oblast, Ukraine, syngenite occurs in druses in halite (Mindat).
