U-Pb baddeleyite dating clarifies age of characteristic paleomagnetic remanence of Long Range dykes, southeastern Labrador

Abstract

A second age of 615 Ma has been obtained for the Long Range dykes in Labrador. This age removes uncertainty, introduced by anomalous paleomagnetic results, that more than one age of dykes trending north-northeast is present in the region. It also establishes that the age of the primary magnetization of the Long Range dykes is 615 Ma. -Authors
