Arseniosiderite has recently been found at the Gambatesa mine in fractures in chert, as yellow to brown rosettes up to 2 mm, associated with clinoclase.
Associated minerals are: quartz, sursassite, adularia, kutnohorite, tilasite, grischunite, arseniosiderite, tripuhyite, rancieite-takenalite and arsenogoyazite.
Occurrence: At the type locality, the mineral occurs on quartz and associated minerals are: Ba-bearing alumopharmacosiderite, barium-pharmacosiderite, arseniosiderite, zeunerite, olivenite, rooseveltite, Co-bearing mawbyite, Co-dominant tsumcorite, waylandite and scorodite.
