Abstract: Quaternary folding, faulting and tilting movements combined with probable compaction of thick, geologically young sedimentary rocks have fundamentally controlled the geomorphological evolution of Brunei and adjacent parts of Sarawak. Areas underlain by anticlinal structures have been up-arched, raised beaches of probable late Mid-Pleistocene age have been faulted and tilted, and drainage has been affected by recent downwarping.
