The resulting powder samples (max 0.06 mm size) were dried at 105°C, 3 gr selected and mixed with 2.5% Moviol solution and finally pressed under 40 kN into alumina rings. These standardized pellets were used for both, XRD and XRF measurements.For the determination of major and trace elements a fully automated wavelenght-dispersive XRF device (SIEMENS SRS 303 AS) was used in the field laboratory. The standard measuring operation comprised 11 major elements (SiO2, TiO2, Al2O3, Fe2O3 total, MnO, MgO, CaO, Na2O, K2O, P2O5, S) and 12 traces (Rb, Sr, Y, Zr, Nb, Cr, Ni, Zn, V, Cu, Th, U).Element concentrations were calculated by setting up calibration curves computed with more than 40 international natural rock standards. 49.588 12.192
