Archeogeophysical prospecting

The laboratory has, for now, two main techniques of non-destructive investigation of the archeological sites, namely the electric resistance of soil and magnetometry. Geophysical prospecting allows the identification of archeological interest points and their detailed characterization, through non-destructive methods with a view to establish some diagnosis that make possible the orientation and concentration of systematic or rescue researches in a short period of time and depending on the scientific objectives. Therefore, the efficiency of the archeological progress through quantitative and financial estimations, in the end meant to assure a better planning and execution of the researches, with minimum costs and high efficiency is possible.

The electric resistance of soil method is realized in two main configurations, namely through shaping (electric tomography of the soil) and surface study. Those methods permit the descriptions of some archeological sites by identifying some primary components such as pits and large ditches, paved roads, building foundations from stone and brick, walls, mosaic, cavities, graves etc. Through the nature of the identified structures lends itself especially to sites with an urban character. The magnetometry method allows the realization of some highly resolution measurements, benefiting of two complete systems, one with alkaline steams (Cesium 133), and one with protons, both in gradiometer configuration (2 sensors). Those prospecting configurations allow the identification of living areas, of pits and ditches, especially of hearths and ovens, of roads, of brick foundations as well as of many other characteristics of a complex archeological site. The applications permit, in this case, the investigation of prehistoric sites, but also of those that have recent urban characteristics. It is recommended the grouped utilization of the available techniques, in order to have an explanation as complete as possible of the recorded anomalies.

Endows

  • SCINTREX SARIS Automated resistivity meter with automatic cables ICS 1 and 2;
  • Caesium Vapors Gradiometer SCINTREX SMART MAG SM4G;
  • Proton magnetometer Base station SCINTREX ENVIGrad;
  • Inversion and modeling 2D and 3D software Geoelectrical RES2DINV and RES3DINV;
  • Software for data processing Geosoft OASIS MONTAJ 5.1.2;
  • Specialized software for data processing Geoscan GEOPLOT 3.0.

As a future plan, we intent to purchase new equipments and to complete the existing ones in order to extend the analysis spectrum in domains like magnetic susceptibility of the soil and geo-radar. We also want to realize the testing of some sensor modern configurations meant to improve the quality and rapidity of the performed measurements as well as offering new analytical perspectives, such as tri-dimensional resistivity meter prospecting.

Services

  • Taking into consideration the large application spectrum of geophysical prospecting, these systems can perform other operations such as sites identification and characterization of illegal deposits containing dumped materials, pipes, cables and tank location for urban development studies and constructions, as well as mineral, oil and gas explorations, groundwater studies. Therefore is needed a scientific collaboration with professionals from these domains.
