Short summary
We provide a tool for fast preparation-free estimation of the Fe3+ content in Al–Fe3+ series epidotes by Raman spectroscopy. The peaks near 570, 600, and 1090 cm−1, originating from Si2O7 vibrations, strongly correlated with Fe content, and all three signals are well resolved in a random orientation. Among them, the 570 cm−1 peak is the sharpest and easily recognized. Hence, the linear trend, ω570 = 577.1(3) − 12.7(4)x, gives highly reliable Fe content, x, with accuracy ± 0.04 Fe3+ apfu.
