...George L. Smith; Hy Almond; Dwight L. Sawyer Abstract Sassolite (H 3 BO 3 ), previously unreported from the Kramer Borate District, California, was found near the base of the borate-bearing shales underlying the ore body. Probertite, ulexite, colemanite, borax, and kernite, all found within...

...Robert L. Smith Abstract Recent finds of sassolite (B 2 O 3 ·3H 2 O) in southern California, Allen and Kramer (1957) and Smith, Almond, and Sawyer (1958) have prompted the author to place on record three heretofore unpublished localities. These sassolite finds, although not as well documented...

...Robert D. Allen; Henry Kramer Abstract Ginorite, 2CaO·7B 2 O 3 ·8H 2 O, and sassolite, B 2 O 3 ·3H 2 O, have been found closely associated in efflorescent masses in colemanite-veined basalt near the head of Twenty Mule Team Canyon, Death Valley. The ginorite is in rhomb-shaped plates, less than...

It forms stout prismatic hexagonal crystals up to 100 μm in size, terminated by rhombohedral faces, and is associated with thermessaite, vlodavetsite, sassolite and salammoniac. Cossaite...

..., Vulcano Island, Aeolian archipelago, Sicily, Italy. It forms aggregates of stout crystals up to 2 mm long in an altered pyroclastic breccia, associated with metaborite, sassolite and adranosite. The unaltered mineral is colorless and translucent, with a vitreous luster; it becomes chalky white after some...

..., maucherite, metarossite, millerite, monazite, nickeline, nitratine, proustite, pyrargyrite, raspite, sassolite, scorzalite, stannite, symplesite, ulexite, xenotime-(Y). The hybrid description of a twin is, in the most general cases, not unique either. In some cases, especially for low-symmetry crystals...

.... The dominant silica phase is opal-A. Minor contents of opal-A/-CT and opal-CT are also present together with halite (NaCl), sylvite (KCl), and realgar (AsS). Accessory phases include teruggite [Ca 4 MgAs 2 B 12 O 22 (OH) 12 ·12(H 2 O)], sassolite (H 3 BO 3 ), and detrital quartz (SiO 2 ). FWHM values reflect...

... of boron (up to 19.8 mass% B 2 O 3 ), cesium (>5 mass% Cs 2 O), and rubidium (>0.5 mass% Rb 2 O). Several boron-bearing minerals have been identified in melt and fluid inclusions, including sassolite (H 3 BO 3 ) and santite (KB 5 O 8 ·4H 2 O). In addition, we have found two new minerals observed...

..., Sicily, Italy. The mineral occurs as sharp translucent crystals up to 0.25 mm in an altered pyroclastic breccia, together with alunite, sassolite, anhydrite and metavoltine. It is orthorhombic ( mmm ), space group Pbcn , with a 10.810(2), b 8.336(2), c 6.822(1) Å, V 614.8(2) Å 3 , Z = 4; the crystal...

...R. C. Erd; J. F. McAllister; G. D. Eberlein Abstract Hungchaoite occurs with ginorite, mcallisterite, sborgite, sassolite, nobleite, ulexite, and, where gypsum and ulexite are abundant, with kurnakovite, inderite, and mcallisterite in surficial matrix as products from weathered colemanite...

...Waldemar T. Schaller; Angelina C. Vlisidis; Mary E. Mrose Abstract Macallisterite is a new hydrous magnesium borate mineral, 2MgO·6B 2 O3·15H 2 o, found in the Death Valley region, California, where it occurs as small pellets of clusters of crystals intimately intermixed with ginorite and sassolite...

... of colemanite and priceite veins in altered basaltic rocks of the Furnace Creek formation of late Tertiary age. The new mineral is associated with ulexite, gowerite, meyerhofferite, colemanite, several undescribed borates, ginorite, sassolite, a manganese oxide mineral, and gypsum. Nobleite is biaxial (+), α...

... in some basaltic rocks in the Furnace Creek formation of late Tertiary age. Associated with gowerite are ulexite, meyer-hofferite, ginorite, sassolite, hydroboracite, and an undescribed magnesium borate. Gowerite is monoclinic and is optically biaxial (+), α = 1.484±0.002, β = 1.501±0.002, γ = 1.550±0.002...
