About Magnesio-hastingsiteHide

Formula:

NaCa₂(Mg₄Fe³⁺)(Si₆Al₂)O₂₂(OH)₂

Colour:

Green to brownish-green

Lustre:

Vitreous

Hardness:

5 - 6

Crystal System:

Monoclinic

Member of:

Hastingsite Root Name Group > Calcium Amphibole Subgroup > w(OH,F,Cl)-dominant Amphibole Group > Amphibole Supergroup

Name:

For its relationship to Hastingsite

Type Locality:

ⓘ Canadian National Railway tunnel, Mont Royal, Montréal, Québec, Canada

The hastingsite-group minerals are defined with 0.5 < ^A(Na+K+2Ca)<1.5 where Na or K is dominant and with the C position occupied by Mg or Fe²⁺ as dominant divalent ions and 0.5 < ^C(Al+Fe³⁺ +Cr+2Ti) < 1.5 where Fe³⁺ is dominant. W may contain (OH), F or Cl.

Magnesio-hastingsite is defined with:

A position: Na dominant
C position: Mg dominant divalent ion
W position: (OH) dominant

Magnesio-hastingsite is the Fe³⁺ analogue of pargasite.

Optical Data of Magnesio-hastingsiteHide

Type:

Biaxial (-)

RI values:

n_α = 1.653 - 1.67 n_β = 1.661 - 1.69 n_γ = 1.669 - 1.7

2V:

Measured: 60° to 90°, Calculated: 68° to 88°

Max. Birefringence:

δ = 0.016 - 0.030
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:

weak
