- La djerfisherite est une espèce minérale de type sulfure, de formule chimique K6Na(Fe,Ni,Cu)24S26Cl. Elle est nommée en l'honneur du minéralogiste américain Daniel Jerome Fisher (1896 - 1988). Sa localité type est la météorite de Kota-Kota, au Malawi. Elle a été trouvée dans des météorites, des kimberlites, des pegmatites et des minerais de cuivre et de nickel d'origine hydrothermale. (fr)

- Джерфишерит (англ. Djerfisherite) — минерал, сложный сульфид с доп. анионами из группы джерфишерита. Назван в честь профессора минералогии Университета Чикаго (Иллинойс, США) (англ. Daniel Jerome Fisher) (1896-1988). Основу кристаллической структуры джерфишерита составляют тетраэдры (Fe,Ni,Сu)S4.

- Djerfisherite is an alkali copper–iron sulfide mineral and a member of the djerfisherite group. The chemical composition is somewhat variable. A Russian study from 1979 on djerfisherite from the Kola Peninsula found the formula K6Na(Fe,Cu)24S26Cl, but a study in 2007 of a samples from Siberia found no detectable sodium and states that the formula K6(Fe,Cu,Ni)25S26Cl is considered the most appropriate. Both crystallographic studies have 58 atoms per unit cell. Sulfur atoms are in three nonequivalent locations, containing 12, 6, and 8 atoms per unit cell. The later study put a copper atom where the earlier study put a sodium atom. More information on the structure and other questions is available, as well as 3-D models. (en)

The later study put a copper atom where the earlier study put a sodium atom. More information on the structure and other questions is available, as well as 3-D models. The Webmineral "Mineralogy Database" site gives the "chemical formula" as K6Na(Fe2+,Cu,Ni)25S26Cl, apparently in error, and an "empirical formula" as K6NaFe2+19Cu4NiS26Cl. Its type locality is the Kota-Kota meteorite (Marimba meteorite), Malawi. It was first described in 1966 and named after professor (1896–1988), University of Chicago. It has been reported from meteorites, copper-nickel hydrothermal deposits, skarn, pegmatite, kimberlites and alkalic intrusive complexes. Associated minerals include kamacite, troilite, schreibersite, clinoenstatite, tridymite, cristobalite, daubreelite, graphite, , alabandite, talnakhite,pentlandite, chalcopyrite, magnetite, valleriite, sphalerite and platinum minerals.
