Name:
Distinguished from lanthanum dominant nordite by Levinson in 1966, who added the suffixes, dividing nordite into two species. The root name is for the northern latitudes, where nordite was first found.
The zinc analogue of ferronordite-(Ce) and manganonordite-(Ce). The cerium analogue of nordite-(La). Also the Sr analogue of illoqite-(Ce).
Related to meieranite.
Related to meieranite.

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.
