Resumen:
The aim of this study is the charactrization by means of petrography and geochemistry of metamorphic rocksthat form the crystalline baament of the study area.Atotal of eight localizations werw identified.The analized rocks are ptetrographically divided into two groups characterized by different metamorphic mineralogy. These two groups represents their different protholits. This supports the results of chemical analysis, which show main differences for SiO2,Al2O3,MgO,K2O,Sr and Rb abundances.
