Magnetometric Researches Used in the Archaeological Studies of the Greek Roman Fortress (Histria) Located on the Shore

In Romania, geophysical methods are normally used to estimate the distribution of cultural relics, before digging. Objects of archaeological interest are usually located within a few meters of the surface. The geophysical studies were carried out within the archaeological site both in 2003 as well as in 2004.Geophysical works were conducted using Geometrics equipment (G856 proton procession magnetometer) with a 0.1nT precision, which allowed for a highly detailed local morphology of the geomagnetic field and for the mapping of the magnetic anomaly. The working technology has been chosen to enable to emphasize mainly abnormal effects produced by sources located at depths of 0-5 m. On the south side of the late Roman fortification, outside the precinct wall, an artisanal area including a furnace for manufacturing building materials dated from the late Roman period, was found as well as some Greek furnaces for manufacturing ordinary brick. The south area of the site has been studied within this research project using the magnetometrical method. Geophysical studies will prove very useful for further archaeological diggings, supplying them with a more clearly defined image on the substratum situation.
