Abstract This study aims to assess the quality of marble blocks after the extraction procedure, by analysing electromagnetic wave signals’ amplitude values obtained with the geophysical method of ground penetrating radar (GPR). To achieve this, we developed an algorithmic process able to process GPR data collected on marble blocks, named ‘Study Marble Blocks Quality’. This newly developed program consists of five different algorithms that were used—in a mainly automatic manner—to examine variations in the reflectivity of the prospected marble blocks. These variations were mostly attributed to internal block heterogeneities and/or fracturing. Our analysis highlights the importance of the GPR amplitude‐based quality assessment of marble blocks, emphasizing on the careful selection of GPR data processing steps as well as the choice of the optimum spacing between measurement lines.
