SummaryGeological discontinuities, lineaments, field observations, and interpreted π-girdles demonstrate a left lateral, NNW trending transcurrent fault in the Sarawak-kiri valley of West Sarawak. Topography and geology also suggest that the fault belongs to an important fracture zone that extends well into Indonesian Kalimantan, and continues in a northerly direction along the edge of the Sunda Shelf beneath the South China Sea.Comparison with transcurrent faulting occuring in the Malay Peninsula and a probable wrench fault between Palawan island and Sabah (North Borneo) reveals the continental part of southeast Asia to have rotated counter-clockwise up to Lower Palaeogene time, probably as a response to spreading of the Pacific ocean floor.

Wrench Fault

Several noteworthy examples of magnetic evidence of strike‐slip faults have been published in recent years, including examples in the Pacific Ocean (Vacquier et al. 1961) and the western Atlantic Ocean (Drake and Woodward, 1963). Aeromagnetic data indicate vertical and horizontal movement along the southern edge of the Hueco Mountains, El Paso and Hudspeth Counties, Texas. The amount of slip is small compared to the published examples, but displacement is of interest because it occurs at the junction of two large, vastly different geologic provinces, the Basin and Range province to the north and the thrust belt of northern Mexico to the south.
