Aravaite is a relatively new mineral, approved in 2018 and to date (June 2022) reported only from the type locality

Localities

At the type locality, the Aravaite type locality, Hatrurim Basin, Tamar Regional Council, Southern District, Israel, aravaite was discovered in pyrometamorphic spurrite rocks such as spurrite marble, larnite pseudoconglomerates, gehlenite hornfels and different paralavas, occurring widely along the rift zone of the Dead Sea. Associated minerals include spurrite, calcite, brownmillerite, shulamitite, carbonate-bearing fluorapatite, brucite, fluormayenitefluorkyuygenite, periclase, barytocalcite and baryte. Aravaite crystallises after ariegilatite and is often overgrown later by stracherite. Flattened crystals of aravaite up to 0.5 × 0.1 mm were detected as epitaxial intergrowth with stracherite or/and ariegilatite crystals (AM 106.158).
