A new application on a marble layer which is ornamental stones is described in this study. Ground Penetrating Radar (GPR) were succesfully applied to detect and map fractures and cavities in a marble layer according to depth in Sivas City Gürün Town Tilkihüyük region. The research area is represented by Upper Miocene-Pliocene lacustrine limestone and mainly composed of calcite with rare amount of quartz and calcedoney including some cavities with different sizes. The aim of this research is to distinguish quickly inact marketable marble areas from fractured ones in order to improve quarry management.
21 parallel profiles, which were 100m lengths, of 5m interval were defined to take the GPR measurements. Measurement station interval set 10cm on each profile. Following data processing on the parallel 2D profiles, constant depth slices were obtained from constructed 3D GPR data block by using the parallel profiles. Finally, Marble layer tichness variations, non-distinguishable fractures, cavities and high-or low-quality marble areas were determined on 2D profiles and depth slices of 3D block without using borehole.
