About Daqingshanite-(Ce)
Formula:
(Sr,Ca,Ba)3(Ce,La)(CO3)3-x(PO4)(OH,F)2x
Colour:
Pale yellow
Lustre:
Vitreous, Greasy
Hardness:
4½
Specific Gravity:
3.81
Crystal System:
Trigonal
Name:
Originally named simply daqingshanite for Mt. Daqingshan, near the type locality. The suffix/modifier was added by the IMA in 1987 and follows the Levinson rule for minerals with essential REE, indicating, in this case, a predominance of cerium.

Optical Data of Daqingshanite-(Ce)
Type:

δ = 0.099

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.

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.

Interference Figure:
This shows the idealized uniaxial interference figure - the conoscopic
(convergent-light, Bertrand-lens-in) view, for a grain cut with the optic axis
centred and vertical. The coloured rings are isochromatics, computed with the
same physics as the Michel-Lévy bar above; the dark cross is the isogyre.
For a genuinely uniaxial mineral viewed this way, that cross stays perfectly stationary if you rotate the stage - unlike a biaxial mineral, where it splits apart on rotation. That invariance is itself the standard diagnostic test for telling uniaxial and biaxial minerals apart at the microscope.
