Investigation on tourmaline occurrence in the metamorphic complex in the north of Golpayegan, Sanandaj-Sirjan Zone

پترولوژی, 2022
The occurrence of tourmaline in the metamorphic complex of the north of Golpayegan is observed within the granitoid mass and schists in contact with granitoid and marbles.Speaking of abundance, tourmaline is less frequently a minor mineral found in granites and granitic pegmatites as well as in low- to high-grade metamorphic rocks (Krmícek et al., 2020)
