North Africa Basement

[ Update this Record ]

Abstract: The dataset contains the location of North African basement outcrops. The
principal reasons for constructing this database are to help in the monitoring
and verification of the Comprehensive Test Ban Treaty (CTBT) and to study the
complex tectonic and geologic problems of the region. This database will also
have an impact in natural hazard evaluation, particularly in understanding the
earthquake occurrences in the region and seismic risk assessment. The data set
can also be used in classrooms as an educational tool.
