Remarks to the geological origin of
the hills "Eight Bells" at the southern Gilf Kebir (Egypt)

The "Eihgt Bells" hills at the
southern edge of Gilf Kebir plateau
Detail of Landsat satellite
The conical high hills,
named "Eight Bells", are located directly southern of the Gilf Kebir plateau.
The geographical position is approximately 22° 47' N and 26° 16' E.
It is remarkable, that all eight
hills are strung on a line. Up to now was not known, whether it is a particularity.
However in images of the satellite "Landsat" we can see crater-shaped structures
in the northwestern extension of the hills chain.
During a visit of the hills in 2006 the author has found now references for
processes. The hills chain is composed
of basal fused Paleozoic
sandstone on a fault. At different
places large blocks represent the methamorhic
Basaltic plugs or a granitic intrusion were not found however. It could exist
however a connection with the crater-shaped structures in the northwestern
direction. Therefore magmatic processes are postulated as origin.
It have a connection with the wide-spread intrusive magmatism in the region,
that has produced numerous craters and dykes.. (Clayton Craters, Gilf Kebir
