Summary. A simple line‐migration technique has been developed and applied to deep crustal reflection data collected in the northern Appalachians of Quebec and central Maine. Preliminary interpretation of these data, combined with the results of gravity and refraction studies, shows thinning of the crust in two distinct steps beneath the Silurian‐Devonian Merrimack synclinorium and shows evidence for Mesozoic crustal stretching and dike intrusion.
