THE TRIASSIC-JURASSIC FUNDY BASIN, EASTERN CANADA - REGIONAL SETTING,STRATIGRAPHY AND HYDROCARBON POTENTIAL

Fundy Basin, one of a series of half graben that formed along the east ern margin of North America during the Triassic/Jurassic rifting of Pa ngaea, lies mainly to the south of the Cobequid-Chedabucto Fault Syste m in Nova Scotia and beneath the Bay of Fundy. Continental red elastic rocks and basalt flows of the Triassic and Early Jurassic Newark Supe rgroup crop out continuously along the Bay of Fundy and Mines Basin co ast of Nova Scotia and at several sites in southern New Brunswick. The se units thicken beneath the waters of the bay to a present-day maximu m of nearly 10 km. Proximal facies preserved along the faulted New Bru nswick margin of the basin consist of upper alluvial fan and fluvial c lastics which grade laterally into sheet flood deposits. Along the gen tly north-dipping Nova Scotia margin, facies consist of distal alluvia l fan, sheet flood and plays mud flat deposits. Facies projections sug gest the probability that petroleum-generating lacustrine sequences ar e widespread along the basin axis. In the Wolfville Formation and lowe r part of the Blomidon Formation these may be overmature but the upper part of the Blomidon Formation and the Scots Bay Formation have the p otential for appreciable quantities of hydrocarbons.
