... solid product phases coesite and jeremejevite decreased with time. Extensive porosity is recognized in jeremejevite and in the cores of early grown acicular tourmaline. Textural relationships indicate that olenitic tourmaline grows at the expense of jeremejevite which acts as a crystalline precursor...

... are famous for spectacular mineral specimens of schorl, foitite, aquamarine, topaz, fluorite, and jeremejevite. Mineral samples from three areas where artisanal mining exposed miarolitic cavities were examined: Lion's Head (LH), Hohenstein Gorge (HG), and Tubusis (TB). Tourmaline, biotite, and associated...

... tourmalines were analyzed using SIMS. Three groups of crystals were analyzed ( Fig. 2 ): columnar crystals (n = 4 in S1 and n = 3 in S2), columnar crystals with inclusions of jeremejevite (n = 3 in S1), and cores of the acicular crystals (n = 6 in S2). All grains were measured in orientations perpendicular...

... parameters, thus the acentric P 6 3 model was rejected. A previous structural study claimed that painite was noncentrosymmetric and differed from the related structures of jeremejevite B 5 [□ 3 Al 6 (OH) 3 O 15 ] and fluoborite B 3 [Mg 9 (F,OH) 9 O 9 ] in having lower symmetry. The structure of painite...

A relatively well-ordered boralsilite was also synthesized at 450 °C, 10 kbar with dumortierite and the OH analogue of jeremejevite. An orthorhombic phase...

... as a single phase product; dumortierite with either quartz or with jeremejevite-OH were the coexisting solids. The starting materials containing 100% excess B 2 O 3 produced an Al-tourmaline with exceptionally low cell parameters similar to those of synthetic excess-boron olenite. Electron microprobe analyses...

...E. E. Foord; C. G. Cunningham Abstract Certain dimetric crystals exhibit anomalous biaxiality (optic axial angle). Changes in biaxiality as a function of temperature for several dimetric crystals—elbaite tourmaline, jeremejevite, A1 6 B 5 O 15 (F,OH) 3 , and synthetic emerald (beryl)—have been...

... common (grossular garnet) and some highly desirable collectable minerals (jeremejevite) were discovered here.
