The western end of the Avalon zone of southern New Brunswick displays a history extending from middle Proterozoic to Triassic lime. About 620 Ma magmatism above a Late Precambrian subduction zone emplaced volcanic rocks and plutons into an orthogneiss-platformal sequence basement which had been modified by mafic intrusion and thermal metamorphism about 780 Ma. About 565 Ma a bimodal sheeted dyke complex accompanied by bimodal volcanism and high-level granite was emplaced into a major mylonile zone during minor spreading or transtension. Shallow water clastic marine sediments accumulated during Cambro-Ordovician lime. From Silurian to mid-Devonian, die northwestern part of the zone subsided along steep faults which served as conduits for bim...
