Resumen:
The Santa Ana pegmatite is located at 32° 53´ 32" S, 65° 55´ 43" W (1340 m above sea level), San Luis province, Argentina, approximately 1000 m east of the highest point of Cerro La Torre. The host-rock of the Santa Ana pegmatite is a medium-grade dark-grey mica-schist with a quartz + muscovite + biotite + plagioclase + almandine + cordierite ± (sillimanite) assemblage that carries dispersed centimeter-sized nodules of altered cordierite. Santa Ana is a beryl type, beryl-columbite-phosphate subtype of a rare-element pegmatite. Its main features were recently mentioned when an interesting association of qingheiite - beusite lithiophilite was described (Galliski et al. 2009).
