Description
Hardness 4.5. Density 2.08-2.16. Color is white, with yellowish or pinkish shades. Crystals usually rhombohedral habitus, forming twins germination on the basis. Found in the form of streaks, small druses , secretions .
Under the blowpipe, it swells up, melts with difficulty, forming a translucent bubble enamel. It decomposes in hydrochloric acid, thus forming siltous silica.
Finding
The main locations of shabazita are cracks and geodes in the effusive rocks in which it is formed. Also, Shabazite was found in places of change of volcanic tuffs under the influence of mineralized solutions, in hydrothermal veins, in deposits of hot springs.
Deposits
Shabazit found in the basalts of Bohemia , Oberstein , as well as in Scotland , Iceland , in the valley of Fassa ( Tyrol ).
In Russia, Shabazite is mined in the r. Chikoi (Irkutsk region).
