Mesozoic Lamprophyre dyke crosscutting Ordovician sediments near Leading Tickles, Newfoundland, Canada
This Mesozoic Lamprophyre Dyke was observed crosscutting Ordovician sediments near Leading Tickles, in Northern Newfoundland, Canada. The dyke displays a minor bridge structure (deflection) coincidental with a low amplitude antiform in the sediments, demonstrating an interation between the intrusion and the pre-existing geology. This dyke is part of a swarm comprising hundreds of dykes in the region that are claimed to be related to rifting prior to the opening of the Atlantic Ocean.
