Abstract Preliminary results of GPR field prospection carried out in the area of the prehistoric mining field Borownia (Ćmielów, Ostrowiec Świętokrzyski District) are presented. This mining field forms a belt (30-50 m wide and 700 m long), starting from the valley edge of the Kamienna River southeastwards. Southeastern and western parts of the site have preserved the original post-exploitation relief. Geology of the Borownia mining field was examined and acquired radiograms revealed three distinct zones of anomaly concentrations. The central zone (B) is clearly a fragment of the prehistoric mining field, confirmed not only by the GPR sounding but also by archeological surveys. The other two zones have not yet been investigated in detail yet but their surface and archaeological examination may determine only whether their underground structures are natural or have been created by humans. Data obtained during the GPR prospection at the Borownia archaeological site confirmed usefulness of 100, 250 and 500 MHz antennas. The relatively large depth range and good resolution are due to favorable geological conditions.

Abstract This paper presents the preliminary results of ground penetrating radar sounding applied at the desert archaeological site in Saqqara (Egypt). The survey was carried out in 2012 within a project realized by Institute of Archaeology, Cardinal Stefan Wyszyński University in Warsaw and the Faculty of Geology, University of Warsaw. One of the key aims of the research was testing the application of ground penetrating radar to non-invasive surveys of desert archaeological sites. Radargrams obtained for area of so called the Dry Moat channel surrounding the Step Pyramid complex have shown the geological structure of its filling. It comprises among others debris-sand conglomerate of diluval origin characterized by a significant content of the clay fraction and clay minerals. Such lithological content strongly attenuate the propagation of EM waves, restricting the depth range of the GPR survey. The conducted geophysical prospection west to the Step Pyramid in Saqqara has confirmed the high applicability of the GPR method in non-invasive studies of vast architectural structures, such as the monumental ditch surrounding the Step Pyramid known as the Dry Moat. It should summarised that high horizontal resolution obtained during GPR survey is a result of local geological structure of the searched area, i.e. strong lithological contrast of the sediments filling the Dry Moat, which, depending on their mineralogical composition

Abstract Geophysical surveys conducted in order to map tunnels and vertical shafts at the Neolithic chert mining field Krzemionki used a ground-penetrating radar(GPR to test hypotheses regarding orientation, depth and subsurface complexity of these voids.Using two-dimensional reflection profiles the vertical shafts, now mostly filled with lithic debris, were easily visible. Amplitude mapping visualized debris at shaft margins as well as a collapsed material inside the voids. Some shallower horizontal tunnels were also visible as sub-horizontal planar reflections generated from both ceiling and floors of these void spaces. Extension of these interpretations to un-mapped areas of the ancient mining district and complexity of these prehistoric mining features could be examined to determine excavation intensity and exploitation techniques used during the Neolithic.

In 2015 the sixth season of the renewed excavations at the Bronze Age city of Hala Sultan Tekke continued in the compound which was ex­posed in Area 6W in 2013–2014. Further evidence of textile process­ing was found. The results of another ground-penetrating radar (GPR) survey in 2014 indicated a new city quarter west of the former. Exca­vations were initiated there in 2015 and parts of the remains of a large compound were exposed. Two occupational phases, Strata 1 and 2, could be determined, both of which were destroyed in a conflagration. Further excavations were carried out in Area A, 550 m to the east of Area 6W and close to the mosque of Hala Sultan Tekke. In 2014 more than 80 circular anomalies were indicated by our geomagnetic survey supported by GPR. Twelve of them were excavated in 2015. Most of them turned out to be backfilled wells of which the fills mainly date from the 13th and 12th centuries BC (Late Cypriot IIC–IIIA). One of the excavated anomalies is interpreted as an offering pit. The preliminary date according to the pottery is roughly the 15th century BC (Late Cypriot IB).

In this article, I propose a new method for calculating and visualizing the pulse radiation within the depth range commonly used by Ground Penetrating Radar (GPR). The text describes the method and illustrates the propagation with several examples. One conventional method is also applied for a quick comparison. The method can be used to optimize GPR antennas and transmit pulse shapes.

In the process of engineering prospective design and constructing, it is necessary to avoid the adverse impact of geological phenomena, such as fault, karst and landslide. Therefore, it’s important to choose a favorable project address by scientific and effective detection with engineering geological conditions. The main exploration method for geological conditions is the geophysical exploration, including: high density electrical method, ground penetrating Radar, seismic exploration method and so on. The discrimination result with a single geological method changes much, and it is difficult to make an accurate analysis of the geological conditions. So we should composite a variety of exploration methods. In this paper, it expounds the fundamental, the working method, data explanations of the high density electrical method and ground penetrating Radar firstly. And then it takes exploration of candidate sites of an aluminum waste disposal plant for example, the geological conditions of candidate sites are analyzed under the two geophysical methods. The study results of engineering site option have a positive role in guiding the work.

ABSTRACT. Magnetic, resistivity and ground-penetrating radar (GPR) methods were applied to Sítio Domingos, a Brazilian archaeological site located in Pará State, to find objects buried by an ancient civilization that may have inhabited the site. Archaeological excavations based on the locations of magnetic anomalies reveal a concentration of ceramic fragments and pots. The correlation between the resistivity models and the soil profile of the study area suggests that the resistivity range of 2000 to 2500 ohm-m represents the archaeological occupation layer. Several anomalous features detected by GPR are correlated with magnetic anomalies. However, when these features are analyzed independently of the magnetic anomalies, they do not conclusively represent the objects being searched. Therefore, GPR is not recommended as the main tool for archaeological prospection in the study area.Keywords: magnetometry, electrical resistivity, GPR, archaeological excavation. RESUMO. Os métodos magnético, resistividade e radar de penetração no solo (GPR) foram aplicados no Sítio Domingos, um sítio arqueológico brasileiro localizado no Estado do Pará, para encontrar objetos enterrados por uma civilização antiga que pode ter habitado a região. Escavações arqueológicas com base nos locais de anomalias magnéticas revelaram uma concentração de fragmentos de cerâmica e vasos. A correlação entre os modelos de resistividade e do perfil do solo da área de estudo sugere que a faixa de resistividade de 2000-2500 ohm-m representa a camada de ocupação arqueológica. V´arias feições anômalas detectadas pelo GPR são correlacionáveis com anomalias magnéticas. No entanto, quando essas feições são analisadas independente das anomalias magnéticas, elas não representam de forma conclusiva os objetos que est~so sendo procurados. Portanto, o GPR não é recomendado como a principal ferramenta de prospecção arqueológica na área de estudo.Palavras-chave: magnetometria, resistividade elétrica, GPR, escavação arqueológica.
