Elemental composition of Kenya 2012 ochre sources

Summary

The results of each ablation performed on an ochre sample are presented in this table with elements in parts per million and oxides in percent weight, as measured by Homogenized Ochre Chip Laser Ablation-Inductively Coupled Plasma Mass Spectrometry (HOC LA-ICPMS). *Mean FeO as percent weight Fe2O3+FeO was determined by Electron Microprobe Analysis of each ochre chip and was used as an internal standard for LA-ICPMS data reduction. Elements labeled in red should be excluded from statistical analyses due to excessive measurements below Limit of Detection (LOD). Yellow cells with dashes represent values that were below the associated LOD.
