Whitlockite discovered in hearth sediments from the Yli-Ii Kierikinkangas archaeological site (Finland). Examples of infrared spectra for a whitlockite containing bone fragment, archaeological sediment from outside the hearth context, and control sediment collected outside of the site. Wavenumbers (cm−1) for each key absorbance band are specified, with whitlockite bands labelled in red. Abbreviations: HAp = hydroxylapatite; HPO4 = hydrogen phosphate; OH = hydroxyl; WH = whitlockite.
