Ground‐penetrating radar imaging of Pleistocene sediments,Boco Plain,western Tasmania

Ground‐penetrating radar surveys across the southern end of the Boco Plain, western Tasmania, revealed a complex sequence of Quaternary glacial and non‐glacial sediments. The subsurface imaging supported previous suggestions of a complex Boco Plain palaeotopography that incorporates a range of depositional environments and multiple constructional events. The ground‐penetrating radar technique enabled imaging of the sediments to 20 m depth, and permitted identification of different sedimentary facies and constructional events due to the significant contrast in dielectric constant within and between the sediments and bedrock. The bedrock and sediment stratigraphy are in broad agreement with drillcore records from the southern end of the Boco Plain and indicate the utility of the method in the initial stages in the investigation of Pleistocene sedimentary sequences of this type.
