- •
Microscopy and EPMA studies were applied to garnets from the Astamal Fe-LREE skarn deposit.
- •
Three type of garnet are identified based on microscopic and mineral chemistry studies.
- •
Garnet (II) yielded the highest Cu and Ni concentrations (up to 1997 ppm and 1283 ppm, respectively), and
- •
There are a grossular/almandine rich discrete domain inside garnet (III).
