Name:
For the hastingsite root name and its potassium and magnesium content.
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+ +2Ti) < 1.5 where Fe3+ is dominant. W may contain (OH),F or Cl.
Potassic-magnesio-hastingsite is defined with:
A position: K dominant
C position: Mg dominant divalent ion
W position: (OH) dominant
Potassic-magnesio-hastingsite is defined with:
A position: K dominant

Based on recorded range of RI values above.
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.
