Abstract
In the present work the PIXE technique at a nuclear microprobe was com bined with the well established electron microprobe analysis (EMPA) te chnique for the characterization of distinct mineral facies coexisting in a metamorphic rock from the Namama Thrust Belt (NTB), northern Moz ambique. The estimated temperature, based on the garner-biotite geothe rmometer, is about 650 degrees C for the rock from the northern part o f the belt (Monapo). Extensive sampling and analysis are to follow in order to test the hypothesis of thickening for the evolution of the NT B and geochemical characterization of the rocks using nuclear micropro be techniques.
