zektzerite
The mineral zektzerite is a member of the tuhualite group and was first found in 1966 by Seattle mineralogist Benjamin Bartlett "Bart" Cannon. It was discovered in the Willow creek basin below Silver Star mountain in miarolitic cavities within the alkaline riebeckite granite phase of the Golden Horn batholith, Okanogan County, Washington.〔 It is named for Jack Zektzer (born 1936), mathematician and mineral collector of Seattle, Washington.〔
The mineral was misidentified as alkali beryl (morganite) at that time. Subsequently in September, 1975, additional specimens of the mineral were found in a float boulder on the north side of Kangaroo Ridge at an approximate elevation of 6500 feet; it was recognized that the material was not beryl.〔Dunn et al.: ''Zektzerite: a new lithium sodium zirconium silicate related to tuhualite and the osumilite group,'' American Mineralogist, v. 62, p. 416-20 (1977)〕
