PALAEOZOIC FLOOD BASALTS IN NORTHERN NEWFOUNDLAND AND LABRADOR

Columnar basalt of the Cloud Hills in northern Newfoundland, previously regarded as of Keeweenawan age, now is thought to be post-Lower Cambrian, since it lies on coarse clastic rocks correlated with known Lower Cambrian strata nearby. A younger age limit is given by a whole rock K-A date of 334 m.y...

Description
Summary:Columnar basalt of the Cloud Hills in northern Newfoundland, previously regarded as of Keeweenawan age, now is thought to be post-Lower Cambrian, since it lies on coarse clastic rocks correlated with known Lower Cambrian strata nearby. A younger age limit is given by a whole rock K-A date of 334 m.y. Perhaps these and similar basalts in southern Labrador represent a flood basalt province, once much more continuous than now.
