Rutherfordine is a secondary mineral formed as a weathering product of uraninite. Associated minerals include uraninite, becquelerite, masuyite, schoepite, kasolite, curite, boltwoodite, vandendriesscheite, billietite, metatorbernite, fourmarierite, studtite and sklodowskite (HOM).

Localities

At the type locality, Lukwengule, Uluguru Mts, Morogoro Region, Tanzania, rutherfordine occurs as powdery masses composed of minute matted fibers, pseudomorphic after uraninite (Mindat, Dana).

At the Shinkolobwe mine, Shinkolobwe, Kambove District, Haut-Katanga, DR Congo, rutherfordine occurs as radiating clusters on uraninite with masuyite (Dana).

At the Dunton Gem Quarry, Newry, Oxford County, Maine, USA, rutherfordine occurs as an alteration product of uraninite (AM 41.127-133).

At the Apex Mine, Reese River Mining District, Lander county, Nevada, USA, rutherfordine occurs radial sprays to 1 mm with uranopilite and zippeite, frequently overgrown with uranopilite (R&M 87.3.275).

At Beryl Mountain Quarry, South Acworth, Sullivan county, New Hampshire, USA, rutherfordine occurs abundantly as dense to earthy pseudomorphs after uraninite in pegmatite, associated with schoepite, vandendriesscheite and uranophane (AM 41.127-133).
