Luinaite-(OH)

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Na(Fe2+)3Al6(Si6O18)(BO3)3(OH)3(OH)
Crystal System:
Monoclinic
Name:
For the type locality, Luina (Heazlewood district, Tasmania, Australia).
Dimorph of:
Tourmaline Group.
The OH analogue of Unnamed (F-analogue of Luinaite-(OH)).

A monoclinic-pseudorhombohedral member of the tourmaline group. The symmetry reduction is caused by cation ordering.
Can be correctly identified only using high-resolution XRD (SXRD) studies. EDS-, EPMA- and standard PXRD-analyses are insufficient for a correct identification of luinaite-(OH).

NOTE: Only a few of the photos uploaded so far show SXRD-analysed samples; all other samples may just be normal schorl.
