چکیده
Among all geophysical techniques, electrical resistivity and magnetic surveying as an integrative approach has been used widely for archaeological prospection at different scales of investigations. In this study, DC (1D vertical sounding and/2D/3D ERT) surveys (total gradient) a multi-scale was applied in highly terraneous site (Tell) with case study to characterize image the various assets depths spatial resolutions. Four critical zones great interest within considered Tell were surveyed. At heart area, three layers depicted clearly from 1D sounding. A thick conductive zone mostly clay is sandwiched between two resistive layers. The topmost layer contains construction debris (dated back Islamic Era), whereas deeper could be related Gezira sand on which probable Pharaonic temple constructed. long 2D ERT profile using Wenner Beta (WB) Dipole–Dipole (DD) arrays 5-m electrode spacing identified shallow high anomalies that ruins fired bricks. Additionally, it succeeded imaging turtleback-shaped sand. elevated rim east west Tell, total gradient maps delineated structures: walls rooms ancient settlers water tanks Byzantine Era. Magnetic modeling assuming 2.5-dimensional models constrained by inversion create realistic representation buried structures. Toward northern part joint application quasi-3D scheme survey revealed anomaly well-defined geometric shape thought crypt or cistern based nearby evidence. overall results integrated some partially excavated parts provided archaeologists comprehensive view subsurface antiquities area.

Integrated remote sensing and geophysical methods can provide detailed information about buried cultural heritage. We implemented an integrated survey protocol (IREGA, Integrated REmote-sensing and Geophysical prospecting for Archaeology) and tested the performance of the method in the area of the ancient Roman town of Aquileia, NE Italy, to define and characterize microareas of archaeological ...

A combination of geophysical methods could be very a useful and a practical way of verifying the origin and precise localisation of archaeological situations identified by different remote sensing techniques. The results of different methods (and scales) of monitoring these fully non-destructive methods provide distinct data and often complement each other. The presented examples of combination...

متن کاملFeral swine disturbance at important archaeological sites.
Feral swine are well known as environmentally destructive invasive animals in many areas around the world, where they degrade native habitats, harm rare plant and animal species, damage agricultural interests, and spread disease. We provide the first quantification of their potential as agents of disturbance at archaeological sites. Our study was conducted in south-central Florida at Avon Park ...
