Extensional tectonics and stratigraphy of Hibernia oil field, Grand Banks, Newfoundland
The tectonic evolution of the Grand Banks involved several episodes of rifting and sequential development of the continental margin. The dominant period of rifting and basin formation in the central Grand Banks was late Callovian to Aptian. Extensional failure of the central Grand Banks crust probably occurred along a shear zone that dipped gently to the west. Listric normal basin-forming faults merge at depth with this detachment system. The listric Murre fault soles at 26 km (16 mi), creating the very deep Jeanne d'Arc basin. Cross-basin transfer faults accommodated different amounts and rates of extension and resulted in the conspicuous offset pattern and funnel-shaped geometry of the Jeanne d'Arc basin. The Hibernia oil field is associated with one of these structural salients. 23 figures, 3 tables.
