Abstract

Paleomagnetic data from 17 sites (76 cores; 152 specimens) reveals that the Nemegosenda carbonatite complex retains a primary remanence magnetization of low stability. The pole position of 43 °N, 178 °W (P0.05: 15°, 24°) for the complex is concordant with a group of poles from other rock units in the Superior Province in the age range of 1000 to 1115 m.y. It is concluded that interpreting the 1036 m.y. K-Ar date as the age of emplacement of the complex is in agreement with the mean magnetization direction having been preserved without structural rotation since the body cooled.
