概要

A total of 217 oriented samples were collected from the Paleozoic rocks at 63 sites on various localities in the South Kitakami Mountains for paleomagnetic measurement. The experimental results suggest that most of the remanent magnetization of the Paleozoic rocks in this area probably owes to the progressive overprinting by a high blocking temperature component. This magnetic overprinting is believed to be related to the plutonism which occurred in Early Cretaceous age. Our former interpretation of Devonian and Carboniferous pole positions and paleolatitudes of the Kitakami Mountains is retracted accordingly.
