The locality is recorded here for a new find of the gemmy bright/dark green demantoid garnets in the metamorphics on the southern flank of Belqeys Mountain, 34 km NE of Takab. Not studied in detail yet (Vachik Hairapetian, July 2013).
Nouri et al.(2020) describe 5 different grossular/andradite localities in skarns in the Azerbaijan district, but only localities near Ghinarjeh and Baba Nazar yields green crystals.
Near Baba Nazar, demantoid is found in a metamorphic horizon consisting of mica schists interlayered with quartzites, marble horizonz and a 50-100m thich horizon of metamorphosed ophiolite ( serpentine, serpentine schist and metabasalt) belonging to the Tabak complex (Chegeni et al., 2021). The metamorphic series are intruded by granites and quartz-porphyres.

✪ Andradite Formula: Ca3Fe3+2(SiO4)3 Description: The individual demantoid crystals from these localities can reach more than 5 cm. Even though the majority of crystals are much smaller, there are surprisingly many crystals over 2 cm, often giving nice matrix specimens. The crystals are rarely transparent, and the locality is of limited interest for the gem industry. References: |
