Rock magnetic, paleomagnetic and magnetic fabric characteristics of the Mishbeh ring complex of Cretaceous age (Ca: 142 ± 15 Ma) have been investigated for establishing a new paleomagnetic pole for this Era. Rock magnetic measurements performed on these rocks reveal that both magnetite and titano-magnetite, with traces of hematite, are the principal magnetic carriers. Demagnetization processes reveal a single magnetic component of interpreted primary origin that reflects the age of this complex. The (ChRM) component isolated from Mishbeh ring complex has a mean direction of D/I=332°/22°, k=71.4, α95=7.1, and N=94 specimens from six sites. This direction corresponds to a north paleomagnetic pole at Lat. 58°N and Long. 290°E, with K=70 and A95=9.2. The consistency of resultant pole with the Cretaceous poles from Egypt .. View More»
