About Cacoxenite
Formula:
Fe3+24AlO6(PO4)17(OH)12 · 75H2O
Colour:
Yellow to brownish yellow, reddish orange, golden yellow, deep orange, green
Lustre:
Silky
Hardness:
3 - 4
Specific Gravity:
2.2 - 2.6
Crystal System:
Hexagonal
Name:
From the Greek κακός for "bad" and ξένος for "guest" due to the fact that the phosphorous content of cacoxenite lessens the quality of iron smelted from ore containing it.
A secondary mineral found in oxidized zones of phosphatic magnetite deposits, in novaculites, in phosphate-rich pegmatites, and rarely in iron-rich sediments and soils.

Uniaxial (+)
RI values:
nω = 1.575 - 1.585 nε = 1.635 - 1.656
Max. Birefringence:
δ = 0.060 - 0.071
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.
