The tall, stringybark jarrah or Eucalyptus marginata forms a belt of forest on extensive sheets of laterite in the southwestern corner of Australia. The deep laterite has been formed by in situ weathering of basement rock, usually granite but occasionally dolerite. The shallow, often sandy gravel topsoil (10-100 cm) is underlain by a bauxite layer (4-5 that lies on a sandy clay pallid zone (20-40 m). In the upper part of the landscape the porous bauxite layer is capped by an indurated layer called caprock. The soil profile down to the top of the pallid zone is shown in Figure 1.
