Abstract

In order to make sure of existence of subsurface wall remnants around the still existing ruins of the Pilisszentkereszt Cistercian Monastery, Hungary, we carried out geoelectrical mapping with a fixed current electrode (AB) distance = 15 m, potential electrode distance = 50 cm, where two AB directions were used, and both Ex and Ey components were measured. The field was subdivided altogether into 162 blocks, each has a dimension of 7m*7.5 m, and in each block we had 240 electrode positions. The two current directions allowed to construct the full apparent resistivity tensor at 210 sites of each block. On basis of altogether 162*210 tensors, various rotational invariants, as (1) determinant, (2) difference of the main elements, and (3) sum of the square of the tensor elements were computed. These maps do not have depth resolution, but the natural and man-made anomalies can be clearly distinguished from each other. Apparent resistivities of various rotational invariants provide practically the same picture (with slight, but characteristic differences), and some other rotational invariants (e.g. the difference of the secondary elements, if they significantly exceed a threshold value) may refer to local inconsistency of the data.
