X-ray investigations of scheelite and pyrite from Aldinac (Stara Planina Mt.)
Апстракт
At one representative sample there was indiced powder diffraction pattern and done qualitative-semiquantitative X-ray powder diffraction analysis. It was established that the investigated sample contains scheelite and pyrite, nevertheless scheelite is of some greater quantity than pyrite.
There were calculated following unit cell dimensions:
scheelite: ao = 5,243(1)Å; co = 11,364(4)Å; and Vo = 312,4(1)Å3;
pyrite: ao = 5,4151(4)Å; and Vo = 158,79(3)Å3;
These unit cell dimensions of scheelite and pyrite are in excellent agreement with the literature datas and they are only with slightly smaller values, and which indicate to minnor exchanging with ions of smaller ionic radius in the structures of these two minerals. Investigations under the UV - light manifested that scheelite fluorescence at pale-blue colour.
