Eveslogite

Eveslogite, ((Ca,K,Na,Sr,Ba)48[(Ti,Nb,Fe,Mn)12(OH)12Si48O144](F,OH,Cl)14), is a mineral found on Mt. Eveslogchorr in khibiny Massif, Kola peninsula, Russia. The name derives from the name of where it was encountered Mt. Evesglochorr. This mineral occurs as an anchimonomineral veinlet that cross-cuts poikilitic nepheline syenite (Hawthorne 2012). This mineral appears to resemble Yuksporite since it forms similar placated fine fibrous of approximately 0.05 to 0.005mm that aggregates outwardly. The color of Eveslogite is yellow or rather light brown. In addition it is a semitransparent mineral that has a white streak and a vitreous luster. Its crystal formation is monoclinic and possesses a hardness (Mohs) of 5. This newly discovered mineral belongs to the Astrophyllite group of minerals and contains structures that are composed of Titanosilicate layers (Krivovichev et al., 2004). Limited information about this mineral exists due to the few research studies carried out since its recent discovery. Regarding to its effect on heat and the of this mineral to the health of an individual has not been explained effectively, thus, ample opportunity for further investigation and research still exists.
