Devonian alkalic basalt dikes of northeastern Newfoundland: evidence of a tensional environment
A suite of diabase dikes intrudes granites and migmatites in the northeastern Gander Zone of Newfoundland. Rb–Sr dates on granites pre-dating and post-dating the diabases show that the dikes were emplaced in the Devonian. The mineralogy and the major and minor element chemistry of the dikes indicate...
