Borehole survey up to the depth of 10 m was done in the Baram-Belait river basin of Brunei. Peat in the Badas area, sometimes exceeding 10 m, rests on sand terrace, which stands for the valley floor in the last interglacial period. The valley floor was transformed into swamp and started to be covered by peat deposit in the Holocene transgressive periods. Peat in the major portion of the Baram-Belait river basin rests on the mangrove mud and tidal flats, which were gulf embayment in the transgressive periods. The outstanding feature of the peat swamps of Brunei is an establishment of the pure stand of Alan (Shorea albida). The reason for this may be ascribed to its unique rooting system and also to the wetter hydrographic condition in the peat swamps of Brunei as compared to those of the rest of insular southeast Asia.
