About OgdensburgiteHide

Formula:
Ca2Fe3+4(Zn,Mn2+)(AsO4)4(OH)6 · 6H2O
Colour:
Reddish brown to brownish red
Lustre:
Resinous, Waxy, Greasy
Hardness:
2
Specific Gravity:
3.11
Crystal System:
Orthorhombic
Name:
Named by Pete Dunn in 1981 after Ogdensburg, New Jersey, USA, which is the borough where the Sterling Mine on Sterling Hill is located and where the species was discovered. (The combined name "Sterling Hill Mine" is incorrect.)
Found as somewhat earthy looking thin coatings usually on willemite-franklinite "black ore" at the type locality. Many ogdensburgite and yukonite specimens have been confused and are incorrectly labeled. At the type locality, ogdensburgite formed with its perfect cleavage perpendicular to the growth surface, although high magnification is needed to see the apparent fibrousness of the ogdensburgite. Yukonite does not show the fibrousness and shows a uniform to waxy appearance.

Optical Data of OgdensburgiteHide

Type:
Biaxial (-)
RI values:
nα = 1.715 nβ = 1.783 nγ = 1.785
2V:
Measured: 5° to 10°, Calculated: 18°
Birefringence:
0.070
Max. Birefringence:
δ = 0.070
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.

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.
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.
Dispersion:
weak
Optical Extinction:
Parallel to {001}
Pleochroism:
Strong
Comments:
X=yellow, Y,Z=red brown
