Abstract
Chlorites constitute one of the main hidrothermal products of the metamorphic alteration of andesites in the Copahue Geothermal Field. They show a rather wide range of variation in their structural and optical
characteristics, regarded with the depth of occurrence. The objective of this work is the study of the chlorites zoning in two drilled holes of Copahue and the relation between the zoning with temperature, by means of XRD analysis and optical study of the chloritic minerals of the COP-2 and COP-3 wells. The use of these minerals as a quick and simple mean for
the thermal characterization of the drilling zone is proposed.
