EXISTINGGEOLOGYMAPPING Digital Geoscience Datasets (DNRM, 2005 Geological Survey of Queensland Geoscience Data; DNRM, 2002 SouthEast Queensland Region Geoscience Data Set; DNRM, 2011 Detailed surface geology Queensland) were reviewed in conjunction with the existing regional ecosystem mapping for the site. In this regard it is noted that the mapped RE12.3.1/ extendingintostage4fromjust southoftheexisting trackis mapped as containing sedimentary rock of the Wongaroo Subgroup.Such geology is considered reflective of, and mapped by DNRM, as being associated with Land Zone 910. Comparativelyareasofalluviumaremappedonthelowerlandsfurthersouthandtothe west and are associated with the Canungra Creek floodplain and thus these areas are consideredtobereflectiveoflandzone3.
