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. RÉSUMÉ On a obtenu un deuxième âge, fixé à 615 Ma, par rapport aux dykes de Long Range, au Labrador. Celui-ci élimine l'incertitude, qu'avaient amenée des résultats paléomagmétiques anomaux, au sujet de la présence de dykes de Long Range d'une direction nord-nord-est de plus d'un âge dans la région. On a en outre établi l'âge de la magnétisation originelle des dykes de Long Range à 615 Ma. [Traduit par la rédaction]
