AbstractThis study presents the methodology used for the processing and interpretation of seismic reflection data in the Jupiter River area of the Anticosti Island. The seismic characteristics of the rock formations investigated are described and time-structure maps of the tops of the Mingan and Macasty formations are presented as well as a map documenting the thickness variation of the Macasty Formation. Subsurface maps present time and thickness estimations that take into account exploration wells and regional seismic data, yet are limited by the spatial distribution and vertical resolution of seismic data. Time-structure maps of the top Mingan and Macasty formations portray a shallow and a deep domain delimited by the Jupiter Fault which probably corresponds to a composite structure with several 'en échelon' fault segments. The thickness map of the Macasty Formation reveals thicker accumulation and/or preservation of this unit within a NW-SE fairway bounded to the northeast by the Jupiter Fault and to the southwest by the Ruisseau Jean IV and the Rivière du Brick faults. North of the Jupiter Fault the Macasty Formation is considerably thinner.
Summary(Plain Language Summary, not published)
This study presents the methodology used for the processing and interpretation of seismic reflection data in the Jupiter River area of the Anticosti Island. The seismic characteristics of the rock formations forming the Paleozoic succession are described and subsurface maps for Mingan and Macasty formations are computed. The maps portray a shallow and a deep domain delimited by the Jupiter Fault. The thickness map of the Macasty Formation reveals thicker accumulation and/or preservation of this unit within a NW-SE fairway bounded to the northeast by the Jupiter Fault and to the southwest by the Ruisseau Jean IV and the Rivière du Brick faults. North of the Jupiter Fault the Macasty Formation is considerably thinner.
