Sarawak can be divided into two geological zones: the Sunda Shield, which extends southwest from the Batang Lupar River (near Sri Aman) and forms the southern tip of Sarawak, and the geosyncline region, which extends northeast to the Batang Lupar River, forming the central and northern regions of Sarawak. The oldest rock type in southern Sarawak is schist formed during the Carboniferous and Lower Permian times, while the youngest igneous rock in this region, andesite, can be found at Sematan. Geological formation of the central and northern regions started during the late Cretaceous period. Other types of stone that can be found in central and northern Sarawak are shale, sandstone, and chert. The Miri Division in eastern Sarawak is the region of Neogene strata containing organic rich rock formations which are the prolific oil and gas reserves. The rocks enriched in organic components are mudstones in Lambir, Miri and Tukau Formations of Middle Miocene-Lower Pliocene age. Significant quantities of Sarawak soil are lithosols, up to 60 per cent, and podsols, around 12 per cent, while abundant alluvial soil is found in coastal and riverine regions. 12 per cent of Sarawak is covered with peat swamp forest. Limestone with well-developed karst topography and cave systems is found scattered from west to east Sarawak, but concentrated in certain regions such as in the Bau district in the west and southwards near the Kalimantan border.
