Surface and underground fluvial activity in the Gunung Mulu National Park, Sarawak

Gunung Mulu National Park's limestone hills harbor extensive fossil and active cave systems, shaped by complex fluvial activity both above and below ground. The study reveals that the region's drainage pattern was initially influenced by northwest tilting of the sedimentary prism but was later modified by active uplift along a northeast-southwest axis, forming an elongate dome centered on Gunung Mulu. This geological evolution explains the distribution of cave systems and terraces in the Melinau valley. The research integrates sedimentary sequences with surface and underground hydrology to reconstruct the park's dynamic geomorphological history.
