Moabite
A valid IMA mineral species
This page is currently not sponsored. Click here to sponsor this page.
Formula:
NiFe3+(PO4)O
Colour:
very dark-brown, almost-black
Hardness:
4
Specific Gravity:
4.324 (Calculated)
Crystal System:
Orthorhombic
Name:
The mineral is named for the Kingdom of Moab, an ancient state that emerged in the late 10th century to 11th century BCE on the territory of the modern Hashemite Kingdom of Jordan.
Unique combination of (species-defining) elements (at the upload time; a similar combination is represented by yakubovichite reported in the same Newsletter). Also compare beershevaite. Chemically also somewhat comparable to lisanite.
New structure type.
Moabite is the first mineral that crystallizes in the α-Fe2PO5 (α-Fe2OPO4) structure type. It has a direct synthetic analogue, and it is isotypic to antiferromagnetic transition metal oxyphosphates.

weak
Reflectivity:
| Wavelength | R1 (%) | R2 (%) |
|---|---|---|
| 470nm | 14.0% | 14.1% |
| 546nm | 13.3% | 13.5% |

Graph shows reflectance levels at different wavelengths (in nm). Peak reflectance is 14.1%.
R1 shown in black, R2 shown in red
Colour in reflected light:
grey
Internal Reflections:
red-brown
Pleochroism:
Non-pleochroic
Comments:
Due to the very high predicted value of the mean refractive index, 1.99, determination of refractive indices in transmitted light was considered impractical.
