This work provides the geochemical characterization data of Maiolica Fm chert from central Italy. The dataset presented here is part of the SiliROck Lithotheque (Sapienza, University of Rome) and includes 97 chert samples collected from the Umbria-Marche succession. The samples have been previously examined using solely non-destructive techniques: petrographic analysis using a stereomicroscope, and geochemical analysis through portable X-ray fluorescence spectroscopy (pXRF). In this study, we report a comprehensive set of data of chert samples originated in the Maiolica Fm. The geochemical dataset and the photo archive are open and reusable to researchers to gain a detailed overview of Maiolica chert for provenance analysis.
