    Over the last billion or so years, what we now know as Nova Scotia, has drifted around the globe in three large pieces, only coming together in one final great collision about 380 million years ago. Each of those pieces were parts of larger land masses:

    • Cape Breton was part of an area known as Laurentia

    • Northern Nova Scotia was part of Avalonia

    • The remaining South-Western area was a part of Gondwana.

    Each area has been significantly changed by volcanoes, mountain building, erosion, faulting and glaciation. At different times they were sea bottoms, swamps, deserts, inland lakes, tropical rain forests, and frozen beneath mile high glaciers. Around 300 million years ago Nova Scotia was attached to Morocco in Africa. It is no wonder that the geology varies greatly in each of the areas.

    Nova Scotia was situated near the equator, wedged between the North American and African continental plates.

    Published structural patterns offshore Nova Scotia combined with detailed structural mapping results offshore Morocco are interpreted in terms of a very specific syn-rift reconstruction of these conjugate margins.

    • The basement embayment beneath the Sable Basin, Canada, correlates withthe basement promontory offshore Essaouira/Safi, Morocco.

    • The basement high of the Tafelney Plateau is interpreted as a high-relief accommodation zone during the late syn-rift stage (Early Jurassic). The actual Middle Jurassic breakup occurred obliquely across this accommodation zone leaving most of it on the Moroccan margin.

    • The area of the Tafelney accommodation zone experienced inversion as the offshore manifestation of the Atlas deformation onshore. Therefore a better understanding of the syn-rift structural evolution of the conjugate margins of both Nova Scotia and Morocco may have an impact on the ongoing hydrocarbon exploration efforts
