Reedmergnerite, NaBSi3O8, the boron analogue of albite, from the Green River Formation, Utah

Reedmergnerite, NaBSi3O8, is a B analogue of albite, occurring with eitelite, shortite, nahcolite, searlesite, leucosphenite, acmite, analcite, and magnesioriebeckite in unmetamorphosed dolomitic oil shales of the Green River formation in several oil wells in Duchesne County, Utah. It is triclinic,...

Description
Summary:Reedmergnerite, NaBSi3O8, is a B analogue of albite, occurring with eitelite, shortite, nahcolite, searlesite, leucosphenite, acmite, analcite, and magnesioriebeckite in unmetamorphosed dolomitic oil shales of the Green River formation in several oil wells in Duchesne County, Utah. It is triclinic, colorless, in stubby prisms with characteristic wedge-shaped ends; biaxial, negative, 2V = 80°, indices of refraction α 1.554, β 1.565, γ 1.573, all ± 0.001. X-ray diffraction and crystallographic data are given.
