4. Geology Summary of the Jeanne
d’Arc Basin
• Jeanne d’Arc d
Basin and adjacent Central Ridge area host most of the
significant oil discoveries in the Newfoundland and Labrador
offshore area (there are also major gas discoveries off Labrador and
an oil discovery in Flemish Pass Basin), including the three currently
rently
producing fields; also Hebron and a series of satellites and field
extensions which are now developed or planned for development
• The basin forms an elongate, roughly NE trending, large half-graben,
encompassing an area of about 14,000 km 2 . It is bounded to the west
by the Murre Fault, to the north by the Cumberland Belt Transfer
Zone (CBTZ) lineament, to the east by the Voyager Fault and to the t
south by the Egret Fault. The basin deepens to the north and shallows
to the south, and contains over 20 km of Upper Triassic to Cenozoic
oic
sedimentary infill in its depocentre, , situated to the north of the Trans-
Basin Fault Zone (TBFZ) and east of Hibernia
• The sedimentary fill of this area was deposited, structured and
fragmented during repeated extensional episodes. Infill includes
clastics, salt and carbonates. Minor trans-tensional tensional tectonic
movements and several strong erosional interludes have also reshaped
the basin and its associated ridges
