One of the spatially most efficient means of non-destructive archaeology are methods of geophysical prospection from area of natural sciences. Nowadays the Institute of Archaeology uses magnetometer (Dual FM256 Gradiometer System, company Geoscan Research) with two probes of Fluxgate type. The main principle dwells in measurement of direction and magnitude of magnetic field in the certain space (basic resolution 0,01 nT - SI unit nanotesla). Mesurements within regular referenced grids resulting magnetogram shows physical representations of subsurface interferences, which may be results of previous human activities (foundations and undeground relics of above ground structures, storage pits etc.). Measurable differences in physical properties of sediments are outcome of differentiated origin and development processes. The infillings of archaeological objects represent - using hign precision measurements - differences towards natural geological background. The results of hign temperature incidences may e. g. detect various types of kilns of object destructed in fire etc.
The geophysical prospection mediates important imformation about subsurface archaeological monuments. In favourable conditions it is possible to identify various types of archaeological objects and other interferences into geological background. On the basis of such information it is possible to optimize efficiency of spatial aiming and overall planning of terrain activities during both rescue excavations or scientific oriented small-scale excavations aimed to resolution of scientific questions.
