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 arfvedsonite granite phase of the Golden Horn batholith, Okanogan County, Washington. It is named for Jack Zektzer, mathematician and mineral collector of Seattle, Washington.

Properties
Synthesis: by fusion of Li2CO3, Na2CO3, SiO2, ZrO2. The resulting material has a brilliant blue-white fluorescence under short-wave ultraviolet light. == Occurrence ==
Occurrence
Zektzerite is a mineral of agpaitic granites with arfvedsonite. It occurs with smoky quartz, microcline, okanoganite, sogdianite, astrophyllite, and zircon. It is found in cavities as euhedral crystals in the agpaitic-granite phase of the Golden Horn batholith, Okanogan County, Washington. It also occurs in blocks of pegmatite as rock-forming grains in a moraine of the Dara Pioz glacier in northern Tajikistan; in the Del Salto pluton in Aysén Province, Chile; as euhedral crystals at Virikkollen, Haneholmveien, Sandefjord, Norway; Ampasibitika, Ampasindava Peninsula, Madagascar; and as gemmy crystals up to 3 cm from Mt. Malosa Malawi. == References ==
