Cadwaladerite is a rare aluminium halide mineral with formula: AlOHCl2·4(H2O). It was reported for an amorphous substance associated with sulfate minerals and embedded in a halite crystal cluster. Its status is uncertain due to inadequate data.[2][3][1]
It was first described in 1941 for an occurrence in mine dumps of the Victoria Segunda mine Cerros Pintados, Iquique province, Tarapacá Region, Chile.[2] Chile. It was named for Charles Meigs Biddle Cadwalader, president of the Academy of Natural Sciences.[3]
