Jeanne d'Arc Basin, Sedimentary basin off Newfoundland, Canada
The Jeanne d'Arc Basin extends across continental shelf waters 340 kilometers east-southeast of St John's, containing layers of marine sediments and rock formations.
The basin emerged during the separation of Pangea supercontinent through multiple geological processes from Late Triassic to Early Cretaceous periods, shaping the North Atlantic Ocean.
The name originates from a former nautical chart marking showing 'Ste Jeanne d'Arc' shoal, representing local underwater rock formations in the Grand Banks region.
The basin holds substantial petroleum reserves within its geological structures, leading to the development of major oil fields including Hibernia and Terra Nova.
Salt deposits from the Argo Formation created conditions for structural traps in the basin, preserving large quantities of hydrocarbons within the sedimentary layers.
