Name:
Named by L.H. Fuchs in 1966 in honor of Daniel Jerome (Jerry) Fisher (14 June 1896, Canton, New York, USA – 18 January 1988, Phoenix, Arizona, USA), mineralogist and professor at the University of Chicago, Chicago, Illinois, USA.
A possible Cu analogue is known (Cu-djerfisherite). Compare a possibly related phase 'UM1977-11-S:CuFeKNi', UM1997-41-S:CuFeKNiPbTl (its Cl-free or S-substituted analogue), chemically very similar chlorbartonite, and somewhat similar UM1990-101-S:CuFeK.
May occur as fluid inclusions in chromite (Potapov et al., 2022).
