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).

Optical Data of FranklinfurnaceiteHide

Type:

Biaxial (-)

RI values:

n_α = 1.792 n_β = 1.798 n_γ = 1.802

2V:

Measured: 79° , Calculated: 78°

Birefringence:

0.10

Max. Birefringence:

δ = 0.010
Based on recorded range of RI values above.

Interference Colours:
The colours simulate birefringence patterns seen in thin section under crossed polars. They do not take into account mineral colouration or opacity.

Michel-Levy Bar The default colours simulate the birefringence range for a 30 µm thin-section thickness. Adjust the slider to simulate a different thickness.

Grain Simulation You can rotate the grain simulation to show how this range might look as you rotated a sample under crossed polars. Each grain retains its interference colour (retardation) while its brightness falls to black at extinction and reaches a maximum between extinction positions.

Thickness: 30 µm Order divisions

Rotation:

Surface Relief:

Very High (positive)
Relative to Canada balsam mounting medium (n ≈ 1.537).

This shows the grain boundary and Becke line effect under plane-polarised light, based on the contrast between this mineral's average refractive index and the mounting medium. It does not take into account mineral colouration.

Focus:

In focus

Interference Figure:

This shows the idealized biaxial acute bisectrix (Bxa) interference figure - the conoscopic view for a grain cut perpendicular to the acute bisectrix, using this mineral's 2V. The two small white dots mark the melatopes - the points where the two optic axes emerge - and are shown only when they fall within the field of view. The coloured bands are isochromatics, and the dark bands are isogyres.

Rotate the stage: at 0°/90° the isogyres form a cross through the melatopes; at 45° they pull apart into curved hyperbolas. That splitting on rotation - absent in a uniaxial figure - is the standard diagnostic test for telling biaxial minerals from uniaxial ones. If 2V is large, the melatopes may fall outside the field of view, as they often do at the microscope too.

Thickness: 30 µm

Stage rotation: 0°

Dispersion:
