Name:

Named in 1999 by O. Johnsen, Robert A. Gault, Joel D. Grice, and T. Scott Ercit in honor of Alexander Petrovich Khomyakov [April 2, 1933 Moscow, Russia - October 12, 2012 Russia], of the Institute of Mineralogy, Geochemistry and Crystal Chemistry of Rare Elements, Moscow, Russia, for his extensive contributions to the mineralogy and geochemistry of alkaline rocks. He described 101 mineral species and was senior author for 80 of those descriptions. The mineral alexkhomyakovite is also named for him.

Optical Data of KhomyakoviteHide

Type:

Uniaxial (-)

RI values:

n_ω = 1.6279 n_ε = 1.6254

Max. Birefringence:

δ = 0.003
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
