| Summary: | This study focuses on the structure and evolution of the Tertiary Queen Charlotte sedimentary basin and its petroleum potential. The study is based on integrated geological basin analysis, which involves compiling all relevant geological, geophysical, and geochemical data; interpreting them using a multidisciplinary approach; and creating a petroleum-exploration model for the basin. The Queen Charlotte Basin lies offshore, and its geologic structure was interpreted from gravity, magnetic, and seismic data. Potential-field trend patterns are similar to physiographic lineaments. Regional faults are the Kitkatla, Principe Laredo/Banks Island, and Sandspit. Their crosscutting relationships, lack of strike-slip displacements, and presence of through going Oligocene dikes, all preclude substantial strike-slip movements in the basin during the Neogene. The origin of the basin by large extension and strike-slip faulting is ruled out; a model based on block tectonics is offered instead. The similarity of orthogonal, ... |
