Opis:
Fault array in an area covered by Quaternary sediments and deprived of bedrock outcrops was investigated using fault trace mapping by geophysical methods and human feedback information from dowsing. The tectonics in the study area is dominated by a ENE-WSW fault zone affecting regional-scale structures. The fault network was approximated by dowsing-enhanced mapping and subsequently confirmed by field geophysical measurements using electromagnetic and radon emanometry methods. A resultant detailed map of structural discontinuities highlighted that combined dowsing and geophysical survey is an effective and reliable tool to identify buried faults. This approach with its low costs and fast field recognition is highly recommended for construction-work planning and for mineral resources exploration and exploitation.

Opis:
This article presents the results of geophysical surveys, which were carried out during the period between 2011 and 2016 at the Roman period cemetery in Nezabylice (Chomutov district, Ústí Region, NW Bohemia). Thanks to these non-destructive surveys, the unusually large scale and signs of the inner structure of the cemetery have been unveiled. On this basis, long-term systematic archaeological research has been carried out, so far uncovering a number of urn graves with military equipment, pit cremation graves, an elite inhumation grave, and several regular structures from Roman period. The results of the comprehensive research suggest that it is the largest and richest cemetery of the Roman period in northwest Bohemia. However, the site is gradually being devastated not only by cyclical agrarian activities but also by the impact of illegal plundering. Therefore, an important aspect of non-destructive surveys is the recording of the current state of the burial ground, the information value of which is gradually degrading.

Opis:
Archaeological and geophysical prospection of the site of Khirbat as-Sar (Sara) in Jordan, carried out by a team from the Polish Centre of the Mediterranean Archaeology (PCMA), University of Warsaw, has resulted in a comprehensive plan mapping all visible architectural remains. A Roman-period sacred compound appears to be a central feature of this site. Pottery collected from the surface has given a time range for the settlement from the late Iron Age through the Mamluk period. The electrical resistivity method using a probe array that allowed ground penetration to a maximum depth of approximately 1.50 m revealed meaningful information on the spatial organization of the site. Numerous high-resistance anomalies were interpreted as a reflection of building remains.

Opis:
Sinkhole (doline) collapse is one of the major natural hazards threatening people and property in the Middle East and North Africa (MENA) region, especially if the bedrock structure is epi-karstic, covered by encrusted material. Many dolines-avens collapses have been recorded in urban and rural areas in Northeast Algeria. Our study identifies localized deformation that may be caused by a sinkhole activity based on the electrical resistivity tomography (ERT) imaging in Setifian high plains. For this task, we conducted 2-D Wenner and Wenner-Schlumberger transects profiles. The geological and hydrogeological study helped to calibrate the resistivity model, and in this regard, expound on the proneness of the limestone layer to collapse. The obtained model highlights the heterogeneity of the subsurface. The inverted transects allowed the investigation of 20 m depth with Wenner array and 52 m with Wenner-Schlumberger. The Wenner inverted models imaged the chimney and different karst networks until 20 m depth; even as the Wenner-Schlumberger models imaged a new karstic cavity in the limestone layer. ERT imaging has once again proven its effectiveness in mapping sinkholes based on its ability to detect resistivity. Our research can certainly benefit karst collapse monitoring in other areas of the high plain region.

Opis:
Rejon Lądka Zdroju jest od kilkuset lat znany z występowania i wykorzystywania ciepłych źródeł. Złoże wód geotermalnych występuje tutaj w specyficznych warunkach geologicznych charakterystycznych dla obszaru sudeckiego. Ma ono charakter szczelinowy i występuje w warunkach naporowych. Rozwój Uzdrowiska spowodował potrzebę lepszego rozpoznania złoża hydrogeotermalnego i jego geologicznego otoczenia. W ramach zrealizowanego programu badań wykonane zostały również badania geofizyczne zorientowane na rozpoznanie ogólnych warunków geologicznych złoża i jego otoczenia. Zastosowane zostały metody: magnetyczna, grawimetryczna i geotermiczna, profilowania VLF, sondowania i profilowania elektrooporowe oraz ciągłe profilowania magnetotelluryczne. W ramach prezentowanej pracy wykonany został przegląd wcześniejszych badań geofizycznych oraz wykonano reinterpretację danych magnetotellurycznych z włączeniem interpretacji danych grawimetrycznych. Reinterpretacja obejmowała przegląd prac pomiarowych, weryfikację procedur i wyników przetwarzania danych pomiarowych oraz została zweryfikowana i rozszerzona interpretacja krzywych sondowań w tym inwersyjne modelowania dwuwymiarowe. Badania te pozwoliły na wyinterpretowanie stref uskokowych, wykrycie anomalii temperaturowych i w bardzo ograniczonym stopniu rozpoznanie przestrzenne szczelinowych poziomów wodonośnych.
The Lądek-Zdrój area has been known for several hundred years as a place of occurrence and use of hot springs. A hydrogeothermal reservoir occur there in specific geological conditions characteristic for Sudetes area. The reservoir is of a fracture type and occurs in artesian conditions. The development of the Health Resort caused the need for the better recognition of the hydrogeothermal reservoir and its geological vicinity. The carried out investigation program included, among others, a geophysical survey for the recognition of general geological conditions of the reservoir and its vicinity. The magnetic, gravity and surface geothermic methods were applied as well as VLF profiling, resistivity profiling and soundings and continuous magnetotelluric profiling. The review of the earlier geophysical surveys and reinterpretation of the magnetotelluric data including gravity data were made within the framework of the presented paper. The reinterpretation works a included review of data acquisition, the verification of procedures and results of data processing as well as verification and an extended interpretation of the sounding curves with use of inverse 2D modeling. As results of the survey tectonic zones were interpreted and temperature anomalies were discovered and, within a limited range, space recognition of the fractured aquifer horizons was made.

Opis:
The depletion of Zn-Pb ores in developed mining areas and the increase in metal prices have resulted in the need to search for new deposits which have not been exploited yet. A project of drilling new exploratory boreholes should be preceded by an interpretation of archival geological data. To obtain the most valuable information on the geological structure leading to its plausible interpretation, it seems to be purposeful and advisable to apply some geophysical methods that are reasonably cheap in comparison with others. The method of electrical resistivity tomography, which in this research uses two of many measurement protocols such as Schlumberger array and dipole-dipole array, is particularly useful. Computer interpretation of geophysical results allows a high resolution 2D and 3D geoelectrical model of rock mass to be created. The study was carried out using the multi-electrode Lund Imaging System manufactured by ABEM, Sweden. In order to evaluate the practical application of this method, Zawiercie Zn-Pb ore deposits were chosen as the area used in previous scientific research. Taking into account mineralization in its economic aspect, the deposits occur at relatively shallow depths of 50-120 m. In the investigated region, the Triassic carbonate formation overlays the Devonian rocks. The Keuper low-resistance clay, occurring on the surface, provides a very good electrical contact between an electrode and the soil. This is why there are favourable measurement conditions in this area. The boundaries between the Keuper, Devonian and Triassic formations are clearly noticeable in the resistivity cross-sections obtained. On the basis of the ERT results, it is possible to locate faulting zones as well as karst systems. One of the profiles clearly shows the occurrence of a low-resistance anomaly correlated with Zn-Pb mineralization, which was confirmed by borehole surveys. However, this early stage of the research with the use of the ERT method cannot unequivocally identify the ore body, particularly as it was conditioned by the limited depth of prospecting.

Opis:
Geophysical prospection and small-scale archaeological excavation were undertaken on the site of Kaštelina, a Late Iron Age hillfort settlement located on the Stolac promontory in the eastern part of Rab island (Kvarner Gulf, Croatia). Within the frame of the “Archaeological topography of the island of Rab” program, a Polish–Croatian team applied a series of multidisciplinary methods to study the occupational history of the site, its preservation, the nature of selected site features and future research potential. Ground-penetrating radar and magnetometer surveys, combined with the implementation of the Amplitude Data Comparison (ADC) method, led to the detection of remains of Late Iron Age building structures distributed over the northwestern side of the Stolac promontory. Archaeological excavations verifying the findings of the geophysical survey resulted in the discovery of a dwelling with associated outdoor features. A preliminary assessment of the outcome of a multidisciplinary approach to the study of the site of Kaštelina emphasizes the importance of the collected data for a general understanding of Late Iron Age settlements and their internal organisation in a wider context.

Opis:
All periods of Egyptian history are represented at Gebelein and it encompasses many kinds of archaeological site found in the Nile valley (that is, cemeteries, settlements, fortifications, temples, rock quarries etc.). The area was a significant centre in the history of ancient Egypt, but its exact role and the reasons for its importance still awaits explanation. That is why the Gebelein Archaeological Project was initiated. The field survey of Gebelein, which started in 2014, aims to recognise the topography of the area and the degree of destruction of the sites and to locate archaeological remains as well as to determine their interpretation and dating. This report outlines the results of work conducted during seasons 2014, 2015 and 2016, which encompassed the archaeological and epigraphic field surveys, geophysical prospection as well as work conducted in the rock-cut chapel of Hathor.

The aim of this article is to present the latest results of geophysical researches executed in April 2017 at the site Gordineşti II-Stînca goală in northern part of the Republic of Moldova. Based on very intriguing discoveries (i.e. remains of a dwelling, part of a clay platform and one pit) during the excavations carried out in 2016 and earlier, it was decided to investigate a larger area using non-invasive geophysical method. As a result, a few types of anomalies of different shapes were identified. It seems that these anomalies indicate the occurrence of remains of the dwellings as well as hypothetical main square between them in the centre of this fortified settlement

Badania archeologiczne, jako przejaw interdyscyplinarnego podejścia do tematu zabytkowych parków i ogrodów, pozwalają na poznanie ewolucji tych założeń oraz odkrycie ważnych dla ich historii obiektów. Możliwości są duże: od wstępnej kwerendy z użyciem zdjęć lotniczych, starych map i innych materiałów źródłowych, przez badania terenowe oraz nieinwazyjne badania geofizyczne, aż do dokładnych badań wykopaliskowych. Wyniki mogą posłużyć za podstawę w trakcie prac restauracyjnych, umożliwić wierną rekonstrukcję, wspomóc naukowymi dowodami wszelkie projekty i strategie konserwatorskie.
Archaeological investigation as part of a cross-disciplinary approach is an important means to trace the evolution and significant features of historic parks and gardens. Its scope ranges from background studies using aerial photographs, historical maps and other records, through analytical fieldwork and non-intrusive geophysical surveys to detailed excavation. The results can be used as the basis for accurate restoration, repair and reliable reconstruction in addition to informing conservation management plans and policies.
