Figure 3.
A geological long section showing subsurface layers and bore locations along chainage with multiple soil and rock types.The long section diagram shows the ground profile along chainage from about 1200 to 2600 metres with bore points labelled A and P 1 to P 21 and B. A legend identifies materials including uncontrolled fill, estuarine clay and silt, alluvial sand and gravel, conglomerate, sandstone, basalt, and breccia. The upper panel shows ground levels and layer boundaries below the reference level, while the lower panel continues above the reference level. Different patterned zones indicate varying geological strata, with inferred and faulted boundaries marked across the section.
