An additional 40-pm Al absorber was used to reduce the intensity of Ca K X-ray lines and allowed the simultaneous measurements of Ca as well as of minor and trace elements. The setup was calibrated using thick pure elements and glass standards as well as thin standards from Micromatter (Prozesky et til., 19

The setup was calibrated using thick pure elements and glass standards as well as thin standards from Micromatter (Prozesky et til., 1995; van Achterbergh et ai, 1995). PIXE spectra were ana- lyzed using the GeoPIXE suite of programs (Ryan et «/., 1990; Ryan and Jamieson, 1993). This package allows the analysis of X-ray spectra with complete corrections for beam stopping. X-ray attenuation, and secondary flu- orescence of thick targets. Backscattered protons were registered with an annular Si surface barrier detector, situated at 176° to the incom-.
