Some Sarawak Soils

Summary The sub‐mature landscape of the country rock (Miocene fine sandstones and shales) along the coast north of Bintulu gives rise under a mean annual rainfall of 150 in. to highly leached yellow soils, comparable to Kellogg's Red‐Yellow Latosols, associated with lowland Dipterocarp rain forest. Areas of level or nearly level coarse‐textured marine or estuarine deposits marking successive stages of the fall in sea‐level during the Pleistocene are associated with ground‐water podzols supporting various forms of the characteristic kerangas forest, which give rise to ‘blackwater’ streams
