Localities

At Tom's Quarry, Kapunda, North Mt Lofty Ranges, Mt Lofty Ranges, South Australia, kingite is abundant as fine grained nodules and as powdery masses, sometimes intimately associated with chalcocosiderite (AJM 17.1.19).

At the type locality, the Fairview Quarry, Robertstown, North Mt Lofty Ranges, Mt Lofty Ranges, South Australia, kingite occurs as small fine-grained nodules in the phosphate deposit, coated with a film of goethite and talc, and associated with vivianite, fluorapatite, leucophosphite, halite and quartz (AM 42.582, Dana, HOM).

At Wilson Springs, Garland county, Arkansas, USA, kingite is associated with opal and sanidine (HOM).
