The paper will describe the work involved to provide an integrated 3D model of the crustal structure and evolution of the Nova Scotia/Morocco continental margin in space and time from rifting to spreading. This model will underpin an understanding of early rift and post rift depositional environments and provide a predictive model for salt deposition and the distribution of Triassic and Early Jurassic source and reservoir rocks. The project includes a number of elements (acquisition of new refraction data offshore Nova Scotia, reprocessing of refraction data offshore Morocco, reprocessing of long offset multi-channel seismic offshore Nova Scotia, merging and integrated reprocessing of potential fields data and integrated interpretation of all these data). The integrated interpretation of these data enable a revised plate reconstruction to be produced together with a model for the along strike variation of rifting styles for the conjugate margins.
The tectonic analysis leads to an interpretation that allows for the possibility of an Early Jurassic source rock system offshore Nova Scotia and Moroccan and provides a model for the distribution of such a source rock system. This in turn greatly enhances the potential for hydrocarbon prospectivity.
