The Bryah Rift: Reconstruction of an Ancient Pericratonic Rift through Combined Geological and Geophysical Interpretation

This PhD thesis presents for the first time a systematic analysis of geophysical data in the Paleoproterozoic Bryah Rift Basin, a fault-bounded basin characterised by voluminous mafic-ultramafic magmatism in the northern margin of the Yilgarn Craton. Investigations of the basin's sedimentary infill, magmatism patterns, structural framework, and architecture were carried out through integration of potential field and geological datasets providing new information that enables a better understanding of the basin's features, genesis and evolution, as well as controls on mineralisation. This approach proved to be effective in portraying the ancient rift in an area where outcrops are poorly exposed.
