NEDUCZA, BORI SZLÁV - PATTANTYÚS-Á., MIKLÓS: Combined radar mapping of North-East corner of the roman Villa-estate, Baláca

Finally, the calculated instantaneous amplitude values are used for construction of anomaly maps referring to different depths. The depths of the maps usually extend from 30 to 120 cm. Maps of shallower depths mainly reflect the ploughed, spread debris zone of the subsurface. The important information, i.e. traces of walls and remnants are more and more outlined on maps of greater depths (50-80 cm). Only remnants having deeper foundation are visible on maps referring to depths of 100-120 cm. In Fig. 2, we show the combined anomaly maps of sites measured during the last three years together with the relevant piece of the original site map. It is clearly visible that the location and direction of the round-wall (A) has to be corrected. Within the first grid, the trace of an unknown building (B) can be detected with a size of about 5 x 5 m outside the fence-wall. It has rectangular walls and there is an almost perpendicular outside-wall that joins to the round-wall. The next grid contains the corner of the round-wall and the building-group No. VI. All of the objects signed on the site map can be followed on the anomaly map but the location has to be corrected. An important information is that the trace of the round-wall disappears at depth of 100 cm while the foundation of the outside, L-shaped building can be seen still in 120 cm depth. The location of the small rectangular object (C) also has to be corrected. The anomaly maps of the NW grid show the continuation of the round-wall and some traces of the building-group signed No. VIII. Summary We summarise the history of the geophysical activity during the last 20 years in the Table attached to the text. The details of measurements carried out and results achieved year by year can be followed in the referring articles listed in the Notes. The application of high resolution radar mapping seems to be a successful method at the site of the Roman villa-estate, Baláca. The reason probably is that the subsurface walls and remnants are in a good condition because disturbances of later ages and the recent agricultural activity did not destroy the foundations of buildings. The prospecting will continue in the future. Acknowledgements Fieldwork and data collection was carried out by I. Holczinger and M. Pattantyús. Data processing and construction of the maps are the work of B. Neducza. S. Palágyi organised and coordinated with great spirit and energy our cooperation. Thanks are due to all participants.
