Baseline data was collected on soils and clays originating from the weathering of limestone bedrock. 79 Neutron Activation analyses are included for each of 21 trace metals and, similarly, the results of 129 analyses for 8 major oxides are also appended. Information is presented on the results of 112 mineral analyses, 79 size frequency analyses, 73 specific gravity determinations, 96 analyses for Liquid Limit, Plastic Limit and Plasticity Index, 16 cone penetrometer compression tests and 11 direct shear measurements. The major factors influencing and controlling the development of residual limestone soils are discussed, as well as differences that result from their formation in Temperate versus Tropical climates. Composition of insoluble residues present in the parent limestones, regional relief, and duration of the dry season were identified as factors most strongly affecting the mineral and chemical composition of the residual clays. Statistical anlayses were also carried out to assess the strengths of inter-relationships among the different variables measured and to identify those most significant in controlling the strength of the soils.
