abstract
  • The mineral zektzerite is a member of the tuhualite group and was first found in 1966 from 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 (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 and recognized that the material was not beryl.
