“…Geochemical characterization and sourcing studies of ochre have used techniques such as LA-ICPMS (Green and Watling, 2007;Eerkens et al, 2012;Bu et al, 2013;Zipkin et al, 2015), solution Multi Collector-Inductively Coupled Plasma Mass Spectrometry (MC-ICPMS) (Eerkens et al, 2014), Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) (Dayet et al, 2015;Moyo et al, 2016), Instrumental Neutron Activation Analysis (INAA) (Popelka-Filcoff et al, 2007;Eiselt et al, 2011;MacDonald et al, 2013), Attenuated Total Reflectance Fourier-Transform Infrared Spectroscopy (ATRF-TIS) (Vahur et al, 2010), micro-Raman and micro-Fourier Transform Infrared Spectroscopy (FTIR) (Bikiaris et al, 1999), Thermogravimetric Analysis (TG), Differential Scanning Calorimetry (DSC), and Mass Spectrometry (Thomas et al, 2011), Scanning Electron Microscopy -Energy Dispersive X-ray Spectroscopy (SEM-EDS) (Huntley et al, 2011), Particle Induced X-Ray Emission (PIXE) (Mathis et al, 2014), and powder X-Ray Diffraction (XRD) (Matarrese et al, 2011;Dayet et al, 2013;Huntley et al, 2014;Cavallo et al, 2015). Research using a suite of multiple archaeometric techniques to analyze mineral pigments is becoming increasingly common (e.g.…”
