System:MonoclinicColour:Dark reddish brown to ...
Hardness:3
Member of:Chlorite Group
Name:Named for an old name of the town, "Franklin Furnace". The name was shortened to "Franklin" in the mid-1910s.
Isostructural with:Chlorite Group


Intergrown clusters or rosettes of dark red brown plates implanted on hodgkinsonite crystals in open cavities. A second much more uncommon find occurred as nearly black filamentous crystals associated with nelenite in open cavities. Franklinfurnaceite has the chlorite group structure, but has unusual chemical composition. It represents the very rare case of a zincosilicate, in which zinc atoms replace Si atoms in (SiO4) tetrahedra (Gaines et al., 1997).
