Ground-penetrating radar method used for the characterisation of ornamental stone quarries

The results have shown that the GPR method can be utilised as a tool for the diagnosis of stone materials prior to their use in artistic work or monuments; therefore, GPR may be considered a technique for material selection. The presence of discontinuities (sometimes visible to the naked eye) explain many of the phenomena and typologies of the stone after its eventual alteration, and such discontinuities could be avoided by means of this pre-emptive work.
