Three different methods have been applied\: electron probe micro analysis \(EPMA\), scanning electron method \(SEM\) and energy\-dispersive x\-ray fluorescence \(EDXRF\) spectrometry. The results of the EPMA and SEM analyses of erratic flint have revealed a largely homogeneous mineral composition, which suggests that mineral composition will be of limited utility in in distinguishing erratic flint. However, EDXRF analysis of a small sample of erratic flint has identified differences in calcium \(Ca\) and iron \(Fe\) content between and among samples of erratic and ‘chocolate’ flint but a much larger sample of erratic flint specimens needs to be analysed to determine the range of chemical composition they contain."]
