AbstractThe tropical red clay soils, formed by the Quaternary weathering of volcanic deposits (and other rock types) in tropical and subtropical environments, have a very open structure and consequent high voids ratio. These soils are particularly sensitive to disturbance during sampling and subsequent transportation and extrusion of the samples. This technical note describes a simple method for obtaining high quality, undisturbed samples from pits in a way that does not require extrusion or trimming of the sample in the laboratory prior to triaxial testing, and only minimal preparation prior to oedometer testing.

Deep weathering in the upper layers of basalt flows in central Queensland led to the deveIopment of lateritic profiles with a surface cover of leached red clay soils overlying ferruginous and mottled zones. Subsequent erosion and bevelling of the weathered mantle left small residuals of the old surface and exposed the underlying weathered zones. In places the mantle was completely removed to uncover fresh rock. A soil catena comprising six zones with associated discrete plant communities developed in these landscapes. Soil differences are related to variations in the intensity of weathering of parent materials and the leaching, translocation, and precipitation of differentially soluble and mobile constituents of the parent rock. The sequence of clay minerals is kaolinite -->kaolinite + randomly interstratified material + montmorillonite --> montmorillonite. The distribution of the plant communities is closeIy associated with variations in soil properties, particularly those which affect water relationships.
