متن کاملMineralogy and comparison of tourmaline chemistry in quartz-tourmaline veins with granitoid host and metapelitic rocks in the Shah-Kuh district (E Iran): An approach to Tin mineralization potential
The Shah-kuh granite batholith (South of Birjand), monozogranite and syenogranite composition, is located on the eastern edge of the Lut block and consists mainly of plagioclase, alkali-feldspar and quartz associated with biotite and tourmaline. The predominant texture of the monozogranite and syenogranite unit is granular to porphyric and granular to micrographic, respectively. Metapelite rock...
متن کاملAnharmonic thermal vibrations and disorder of atoms in tourmaline
Elbaite (space group R3m), a Li-bearing tounnaline with general fonnula of XY3Z"(B03hSi,,0,,W4, has 5 kinds of cations and 8 kinds 01'0 (including W). Of the structural studies of tourmaline, those of Gabrielle Donnay and hcr group were unique in focusing on the structural aspccts ofthc primary pyroelectricity (Donnay, 1977" etc). Donnay (1977) refined the structure of elbaite, and tound that t...
متن کاملQuartz-Tourmaline Veins in the Northern Sierra Nevada Area
Tourmaline-bearing quartz veins and replacement deposits, commonly copperand gold-bearing, are found in unusual concentration in northwestern Nevada and adjacent northeastern California in Triassic and Jurassic arc rocks and in the Cretaceous plutons that intrude them. Mines and prospects that exploit the tourmaline-bearing deposits are found in a zone approximately 70 miles long and 50 miles w...
متن کاملTowards Zn-dominant Tourmaline: a Case of Zn-rich
Tourmalines are a group of minerals which may concentrate various accessory 16 components, e.g. Cu, Ni, Zn, Bi, Ti, Sn. The paper presents fluor-elbaite and elbaite from a dyke of 17 the Julianna pegmatitic system at Piława Górna, at the NE margin of the Bohemian Massif, SW 18 Poland, containing up to 6.32 and 7.37 wt.% ZnO, respectively. Such high amounts of ZnO are 19 almost two times higher ...
