Named for the La Sal district in Utah, USA where the type locality of the mineral at the Vanadium Queen mine is found. Lasalite is rare mineral that can be found only in the La Sal district in only a couple other mines besides its type locality. It is found “as efflorescences in oxidized portions of paleochannel uranium-vanadium deposits of the Colorado Plateau type.” Lasalite crystals will dehydrate to a tallow powder and are soluble in water.

Named after the type locality at the Grand Reef mine in Laurel Canyon in Arizona, USA. Other localities for Laurelite are found in Italy and Greece. Laurelite occurs in isolated vugs in oxidized, low-temperature lead-copper-silver deposits. Associated minerals include grandreefite, pseudograndreefite, aravaipaite, galena, fluorite, anglesite, linarite, caledonite, and quartz. Laurlite will slowly dissolve in cold water.
