Mesozoic Igneous Activity In Egypt
MetadataShow full item record
A geochronological sequence of the main phases of igneous activity in Egypt during the Mesozoic is presented in this paper. This is essentially based on scrutinized isotopic age data. New K / Ar ages are also included. Three main phases are outlined: 1. Early Triassic- Late Permian (230 ± 10 Ma). 2. Late Jurassic - Early Cretaceous (140 ± lOMa). 3. Late Cretaceous (90 * lOMa). An attempt is made to relate these phases with tectonic events.
