Abstract:
Road construction work of the Pan-Borneo Highway at sections of the Lambir
Hills has created a few fresh temporary outcrops. Of particular importance is
an excellent outcrop of the Mid-Miocene Unconformity (MMU), which we called the
“White Cliff”. An equally spectacular outcrop shows Lambir sandstone offset in
strike-slip against a sand wedge and the older Setap Shale, at the inferred
(West) Baram Line location. The outcrop is an additional data point for the
Baram Line regional strike-slip system, which has been mapped previously with
some confidence on both seismic and gravity data.
