ABSTRACT
The research in geophysical methods increase the possibility of use in other, never reviewed areas. A construction of the relative gravimeters makes the use method of microgravity possible for the searching of cavities and free spaces in subsoil, not only in opened areas but in urban areas as well. Microgravity method was used for the research in church of Saint Mary in Klastor pod Znievom village before. This church was chosen after discussion with local historians, they were presuming that the church is that kind of sculpture, where the cavity could be found. After necessary measurements, calculations and creating of Complete Bouguer anomaly map, there is a possibility to define the existence and the position of the cavity. On the other hand, one method is not enough, so there is a necessity to use other method. The method of GPR research shows as a good one, it is not only fast but it is reliable in the same time. As the measurement showed, both of these methods could be used in urban areas. It is good to focus on right calculation of terrain corrections. With the big influence of the walls gravity there can easy come to a mistake of bad interpretation due to Simple Bouguer anomaly. Application of these methods was also used in other historical site, church in Banska Bela. A result of this research supports the correctness of this combination and showed us the same final results if not even better.
