In this article we present some results of ground‐penetrating radar (GPR) studies carried out at the Lapa do Santo archaeological site. This cave is within the Lagoa Santa karstic region, Minas Gerais State, Brazil. Results from 44 GPR profiles obtained with 400 MHz shielded antennas indicated anomalous hyperbolic reflections and areas with high sub‐horizontal reflection amplitude suggesting archaeological and geological potential targets, respectively. These results were encouraging and were used to guide excavations at this site. Excavation of test units (metre by metre) allowed identifying an anthropogenic feature, e.g., a fire hearth structure and natural features, such as a stalagmite and top of bedrock. Results also indicated the importance of the GPR survey as a tool for orienting archaeological researches, increasing the probability of finding archaeological interest targets in an excavation program in an area of environmental protection.

Karst and pseudo-karst result from natural phenomena associated with the circulation of water through soluble geological environments, causing subsidence, sinkholes, cavities and collapses. During the last five years, Guerrara area (southern Algeria) was the subject of multidisciplinary studies to characterize the geological formations and assess the impact of their distribution on the movement of water surface and deep aquifers. This study undertaken in three sites from the Guerrara area aims at the recognition and the characterization of underground voids (size, extension) by geophysical methods such as vertical electrical soundings and electrical tomography combined with 2D electromagnetic imaging ground penetrating radar GPR.

“…Drahor et al, 2008;Fischer et al, 2016;Tsokas et al, 2009), but it also can provide very useful information for a sedimentological study (Hausmann et al, 2013;Reis et al, 2015). While the advantages of GPR in locating underground structures of archaeological and geological interest have been discussed by several authors (Conyers, 2015;Davis and Annan, 1989;Goodman, 1994;Leucci et al, 2012;Porsani et al, 2010), GPR use in archaeological/palaeontological field research is less established; in fact, very few authors have studied its benefits (Beck and Weinstein-Evron, 1997;Bernhardt et al, 1988;Leucci, 2013).…”

The sedimentary filling of two Slovak Neanderthal sitesthe Prepoštská Cave near Prievidza (Micoquian) and the Čertova Pec Cave near Radošina (Szeletian, Mousterian) was investigated, while archaeological and palaeontological studies have shown these caves are very important sites from the viewpoint of the ancient man settlements. No geophysical research had previously been conducted here, therefore ground penetrating radar (GPR) and electrical resistivity tomography (ERT) geophysical methods were applied in order to expose its depths for future archaeological and palaeontological field campaigns. The GPR survey at the Prepoštská Cave revealed a disrupted zone in the southwest (SW) corner of the investigate area, encapsulated in travertine surrounding the bedrock layer identified at a depth between 0.4 to 2.4 m. This discovered zone is assumed to be an undocumented recent excavation zone. The combined ERT and GPR survey also identified at the Čertova Pec Cave, aside from some main structures (large limestone blocks, loamy-clayey sediment in the central part and debris), intact cave sediments, deposited under the debris filling and large limestone block, located at approximately 2 m depth in the back part of the cave, close to its northeast (NE) entrance. These unconsolidated intact deposits represent the lower part of the Mousterian horizon. Thus, the geophysical survey supported previous hypotheses on the assumed existence of deeper layers with potential archaeological and/or palaeontological content, which have since been spatially defined.
