About FranklinfurnaceiteHide

Formula:

Ca₂Fe³⁺Mn²⁺₃Mn³⁺(Zn₂Si₂O₁₀)(OH)₈

Zn is tetrahedrally coordinated.

Colour:

Dark reddish brown to brownish black

Lustre:

Sub-Vitreous, Resinous, Waxy

Hardness:

Specific Gravity:

3.66

Crystal System:

Monoclinic

Member of:

Chlorite Group

Name:

Named in 1987 by Pete J. Dunn, Donald R. Peacor, Robert A. Ramik, Shu-Chun Su, and Roland C. Rouse for an old name of the town, "Franklin Furnace". The town became "Franklin [borough]" on April 23, 1913.

Type Locality:

ⓘ Franklin Mine, Franklin, Sussex County, New Jersey, USA

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).
