The Nature of Triassic Continental Rift Structures in the Gulf of Maine.
Abstract
An interpretation of seismic reflection profiles made across the Gulf of Maine and Georges Bank reveal the region underwent a major period of crustal rifting during the Triassic period. Three rift systems are delineated and a detailed comparison is made between the three systems and the Triassic Neward series onshore. A stress-strain analysis of the Triassic fault pattern in the Gulf of Maine is made and observed structures and related stress conditions are related to a sequence of six tectonic episodes beginning with initial graben formation in Late Triassic and ending with regional collapse and the onset of geosynclinal deposition in Middle Jurassic to Early Cretaceous.
