Abstract

In this work we present new data concerning the pressure character of metamorphism in the Aysén Eastern Andean Metamorphic Complex. The parameter d060,331̄ of the K-white mica from basement politic rocks was measured as a barometric indicator. Three sample groups from different areas were considered, for a total of 69 samples. All measured values suggest a metamorphic setting characterised by intermediate to high pressure.
