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
volcano- tectonic
processes. The hills chain is composed
of basal fused Paleozoic
sandstone on a fault. At different
places large blocks represent the methamorhic
basement.
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
Crater Field
etc.)
