No Data

Comments:


Associated with Vlasovite and Eudialyte (Russia) or with agrellite (Canada);
Vlasovite fluoresces yellow under SWUV and the Gittensite seems to be fluorescing a slightly paler yellow or cream. The Gittensite does fluoresce under LWUV too, but not the Vlasovite.(Source: http://www.middleearthminerals.com)'>http://www.middleearthminerals.com)'>Associated with Vlasovite and Eudialyte (Russia) or with agrellite (Canada);
