In this work we report about the micro-PIXE characterization of lapis lazuli rocks, for a provenance study. The final aim is to find markers permitting to identify the origin of the raw material coming from three quarries in regions of historical importance: Afghanistan, Pamir Mountains and Siberia. Due to the heterogeneity of lapis lazuli we concentrate our attention on single phases instead of the whole stone; in particular we focused on the diopside, the more frequent accessory mineral of lazurite, the main phase of lapis lazuli.

Abstract
In this work we report about the micro-PIXE characterization of lapis lazuli rocks, for a provenance study. The final aim is to find markers permitting to identify the origin of the raw material coming from three quarries in regions of historical importance: Afghanistan, Pamir Mountains and Siberia. Due to the heterogeneity of lapis lazuli we concentrate our attention on single phases instead of the whole stone; in particular we focused on the diopside, the more frequent accessory mineral of lazurite, the main phase of lapis lazuli.
