| dc.description.abstract | This thesis presents a structural analysis of the Ou Kaapse Weg Fault Zone, situated within the Silvermine Nature Reserve, with a specific focus on its interactions with the Muizenberg Fault Zone. The study aimed to characterise the fault systems, document their structural complexities, and place them within the broader tectonic framework of the region. A combination of detailed field mapping, remote sensing techniques, lineament extraction, and kinematic analysis was employed to identify and interpret the fault and joint systems in the area. Results indicate that thefaults within the Ou Kaapse Weg Fault Zone, particularly the Silvermine, Waterfall, and Boyes-Drive Faults, as well as the Muizenberg Fault Zone are predominantly strike-slip in nature, with significant evidence of left- lateral (sinistral) movement. Additionally, four major joint sets were identified: joint set-1 (NW-SE), joint set-2 (NE-SW), joint set-3 (E-W), and joint set-4 (N-S), which are spatially associated with the dominant fault trends. The spatial distribution and density of joints were found to increase significantly near fault zones, forming well-defined damage zones. These areas of intense fracturing are characterised by both orthogonal and conjugate joints. The presence of displaced joints and joint step-overs further underscores the complex stress regime and kinematics of the area. | |
