About NataliyamalikiteHide

Nataliya Malik
Formula:
TlI
Crystal System:
Orthorhombic
Name:
Named for Nataliya Malik, from the Institute Of Volcanology And Seismology - Laboratory of Active volcanism, Petropavlovsk-Kamchatsky, Russia

Known synthetic analogue. Chemically the iodine analogue of lafossaite (which has, however, a different crystal structure).

Probably formed at temperatures below 175 oC. Some of the crystals show cubic symmetry (of a supposed polymorph of lafossaite).
