Abstract: Kudat Peninsula, consist mostly of Lower Miocene sedimentary rocks that shows a complex structural style due to continuous deformation. The deformation produced large-scale folds on three major imbricate thrust slices that trends WNW-ESE in the northern, middle and southern part of the peninsula. The northern thrust slice shows a huge fold plunging steeply to the southeast. The middle thrust slice shows a Z-shaped drag fold, whereas the southern thrust slice shows a W-shaped fold pattern. The Bangau Fault Zone and Parapat Fault Zone which are characterised by melange separates the northern, middle and southern thrust slice, respectively. The southern thrust slice is separated from the Crocker Formation by the Laya-laya Fault Zone. The deformation was probably caused by progressive N-S transpression related to the collision of the Dangerous Grounds with NW Sabah along the NW Borneo Trough.
