Abstract
We present the results of the application of the tensor resistivity method to the assessment of the state of conservation of some architectonic features of the S.Giovanni a Carbonara monumental monastery (Naples, Italy) and to the recognition of buried remains in the archaeological site of the roman Port of Claudius at Fiumicino (Rome, Italy). The 3D tomographic approach, based on the concept of resistivity anomaly source occurrence probability, has been used for the analysis of the invariant parameter related to the trace of the determinant of the apparent resistivity tensor.
Highlights
High-resolution acquisition techniques favour the application of 3D tomographic imaging in non-invasive microgeophysical testing for monument preservation and in nearsurface geophysical prospecting for archaeology

Summary
High-resolution acquisition techniques favour the application of 3D tomographic imaging in non-invasive microgeophysical testing for monument preservation and in nearsurface geophysical prospecting for archaeology. Probability tomography is gaining increasing importance for its objectivity and reliability. It has the notable advantage of not requiring any a priori assumption about the structures to be imaged. The aim of this paper is to illustrate the results of the application of the Tensorial Resistivity Probability Tomography (TRPT) method to the assessment of the conservation state of a few architectural features in the San Giovanni a Carbonara ancient monastery (Naples, Italy) and the recognition of a marble cargo sunk in the roman Port of Claudius at Fiumicino (Rome, Italy)
