| Abstract/Notes | Topaz specimens from a number of Norwegian localities are now being examined in this Institute by spectrochemical and other methods. However, two specimens so labelled in the collection of the Mineralogisk- Geologisk Museum of the University of Oslo gave strong spectral lines of the elements B, Ca, Si. Other constituents (Al, Fe, Mg, Mn, Be) occur in quite subordinate quantities or traces only. Thus the mineral danburite is suggested. That the mineral is indeed identical with danburite was subsequently established by its optical properties and by its X-ray powder pattern. |
