Abstract

In this paper we present the results of a direct current geoelectrical surveying made for exploring an underground building in the Roman age fort of Porolissum. It was assumed that the building was a Mithras-temple. It was made of volcanic rock surrounded by clayey soil. We carried out the measurements along two sets of sections perpendicular to each other. We made two surveys: first using Wenner-Schlumberger array and second time a dipol-dipol array. We inverted the apparent resistivities as a 3 dimensional dataset with the software RES3DINV. The boundaries of the building could be easily identified, and we got information about the building’s inner structure, too. The reisistivity distribution showed where bigger rocks, the former archeological trenches, the walls and the collapsed parts of the building were located. There were no significant differences between the results of Wenner-Schlumberger and dipole-dipole arrays, the lateral distribution of the resistivity was almost the same. Later the archeological excavations proved the results of the geophysical measurements in detail.
