... are of post-Archean age. More exactly their age can be estimated from indirect evidence, mainly from paleomagnetic data. Comparison of paleomagnetic and petrographic data for two types of ultrabasites (clinopyroxenites and koswites) helped to refine their paleomagnetic characteristics. The obtained paleopole...
