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 arfvedsonite granite phase of the Golden Horn batholith, Okanogan County, Washington.[3] It is named for Jack Zektzer (born 1936), mathematician and mineral collector of Seattle, Washington.[2]
The mineral was misidentified as alkali beryl (
Properties
Synthesis: by fusion of Li2CO3, Na2CO3, SiO2, ZrO2. The resulting material has a brilliant blue-white fluorescence under short-wave ultraviolet light.[citation needed]
