About DozyiteHide

Jean Jacques Dozy

Formula:

Mg₇Al₂(Al₂Si₄O₁₅)(OH)₁₂

Colour:

Colourless, violet

Lustre:

Pearly

Hardness:

2½

Specific Gravity:

2.66

Crystal System:

Monoclinic

Name:

Named by Sturges W. Bailey, Jillian F. Banfield, William W. Barker, and George Katchan in 1995 in honor of Jean Jacques Dozy (18 June 1908, Rotterdam, Netherlands – 1 November 2004, The Hague, Netherlands), Dutch geologist who discovered and named the Ertsberg ore province in 1936.

Type Locality:

ⓘ Ertsberg East Complex (GBT), Ertsberg Complex, Gunung Bijih District, Mimika Regency, Papua Province, Indonesia

A 1:1 regular interstratification of trioctahedral serpentine and trioctahedral chlorite units. The formula is halfway between the compositions of the closely associated discrete magnesium chlorite (clinochlore) and the discrete serpentine (amesite).

Optical Data of DozyiteHide

Type:

Biaxial (+)

RI values:

n_α = 1.575 n_β = 1.575 n_γ = 1.581

Max. Birefringence:

δ = 0.006
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:

Moderate (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.

No measured or calculated 2V is on file for this mineral, so the value used here (0°) is estimated from its recorded refractive indices and optic sign, not from a direct 2V measurement.

Thickness: 30 µm

Stage rotation: 0°

Dispersion:

very weak

Pleochroism:

Visible

Comments:

X: Y : colorless; Z: very pale tan in thick crystals
