Abstract

Geometrical effects occur when primary x-rays irradiate a mineral inclusion which lies close to the boundary between it and a surrounding mineral having a different chemical composition. An investigation of one of these near-edge effects was performed in the case when x-ray microfluorescence is applied for analysis. Analytical mathematical expressions were developed to correct for this effect and were tested exper imentally.
