Description	The bones coming from archaeological sites do not contain the original trace element metal concentration. Due to the diagenesis these fossil bones were enriched during the deposition time in elements typically presented in soil (e.g. Fe, Mn, Cu, Al). The gradient of soil elements penetration into bones depends on the external conditions, mainly the composition of the surrounding soil, pH, water conditions, microbial activity and of course the character and a degree preservation of the specific bone. The experiment was based on spatially resolved analyses (line scans) of the cross section areas of contaminated bones using LIBS and LA-ICP-MS (Laser Ablation Inductively Coupled Plasma Mass Spectroscopy). Some of the bone samples were excavated from soil, others came from metallic coffins. For this experiment LIBS instrumentation and double-pulse LIBS were used.
