The formation of mawbyite is probably related to the pH of circulating waters in the oxidation zone
At Kintore, New South Wales, Australia, mawbyite occurs in the oxidised zone on spessartine quartz rocks in an arsenic-rich reaction halo associated with members of the corkite-beudantite series, adamite, olivine, duftite, mimetite, bayldonite, hidalgoite and pharmacosiderite.
