the presence of various objects underground, objects which when made of certain
materials would disturb the natural magnetic value of the soil.
It has been observed that the remanent effect resulting from burning (red-brick,
slag, ashes) gives a very strong magnetic reading between AO and 150 gamma. This
phenomenon permitted nine clusters of kilns to be located very precisely regardless of
their being 0.5 to 1.8m below the surface. These results were confirmed archaeologically
on site R.6. Here a trial pit 2 x 6m was dug in a dune where no traces of any kind of
human activity were to be observed on the surface. Upon removing 1.6m of overlying
dune, the tops of the walls of two kilns of red-brick appeared, their inner surface
covered heavily with slag. Since they are of a different construction than the already
known Dongolan kilns nearby, they appear to have had a different function. The site
can be dated to the later Classic Christian period (10^-11^ century).
On the site of cemetery TEQ the magnetic method was instrumental in establishing
individual concentrations of tombs and the extent of the burial ground. The results
were extremely helpful in this case for the surface here has suffered extensive erosion
and no tomb superstructures are to be seen.
Some clearing was done on the site of the Rock tombs (RT) in the north end of the
concession area in order to verify the observations made on the basis of a geophysical
survey conducted in 1988. It is certain at present that no other rock tombs existed here
beside two imposing monuments RT.l and 2, excavated in 1971 and 1981 respectively and
dated back to the very beginning of the Christian Period in Dongola.7
