Tanjong Batu
The cliffs at Tanjung Batu provide a spectacular exposure of the Middle Miocene clastics of the Lambir Formation. Coastal, shallow marine sandstones and mudstones are overlain by some 16m of stacked estuarine sandstones, which form the main body of the cliff. The top of the escarpment is itself sharply truncated, with horizontal-laying terrace deposits resting on the folded Miocene strata. The estuarine sandstones are interpreted as the back-filling of an incised valley and their base is a sequence boundary.
