Abstract A Monte Carlo model was developed for simulation of x‐ray fluorescence from cylindrical mineral grains in geological samples including primary and secondary fluorescence events. The inter‐element and geometrical effects in XRF microanalysis of mineral grains were studied. Calculations were performed for grains of ZnS located in a CaCO 3 matrix. The results of calculation indicated that the intensities of excited characteristic x‐rays depend strongly on the diameter and thickness of the irradiated grains.
