Abstract

Mass transport deposits form a significant component of deep marine and slope sediments. Knowledge of the architecture of such deposits is relevant to assessment of them as potential geohazards for drilling rigs. The objective of the thesis research is to explain the structural relationships in the Early Cenozoic Thorvald Mass Transport Deposit and to use these findings to relate the internal structures to kinematics of the failure process. The Thorvald Mass Transport Deposit within the Jeanne d'Arc Basin has distinct structural domains, known as the head, translational region, and toe, which are analogs to structural elements within fold and thrust belts. The intricate distribution of the thrust faults, back thrusts, lateral transfers and extensional faults signifies the forces present upon the failure. This distribution is mapped in the Thorvald Mass Transport Deposit (MTD), offshore Newfoundland. This analog enables better understanding of the processes of failure and deformation. The MTD is defined by conventional seismic mapping and enhanced by seismic attributes within the Flying Foam 3-D dataset from the Jeanne d’Arc Basin.
