Interpreted Faults, North-West Murray Basin

This dataset depicts the location of the Danyo, Hindmarsh, Tyrell, Avoca and Leaghur faults in the north-western Murray Basin in Victoria. The faults have been digitised from Macumber (1991) and Robson and Webb (2011). These north-south oriented faults appear to truncate or interrupt a number of cross-cutting structures in the Murray Basin. The Hindmarsh, Tyrell, Avoca and Leaghur faults all influence modern day stream flows which may be indicative of an earlier impact on the aquifer if movement has occurred regularly over the Tertiary period.The dataset was compiled by GHD to inform the report 'Potential Influences of Geological Structures on Groundwater Flow Systems' for DEPI's Secure Allocation Future Entitlements (SAFE) Project.
