Resumen:
Fluorite, infilling fractures of volcanic rocks affected by very low grade metamorphism (VLGM) under zeolite and prehnite-pumpelleyite facies located at Chapelco Hills, in assemblages with fluorapophillyte, sericite and cooper oxides, have been found. It indicates that circulating fluids were rich in F. The presence of this element would be due to exhalative processes, related to the emplacement of Miocene granitic magmas in the area.
