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.\n\nThe 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.

本数据集标注了维多利亚州墨累盆地（Murray Basin）西北部的丹约（Danyo）、欣德马什（Hindmarsh）、蒂勒尔（Tyrell）、阿沃卡（Avoca）和利厄（Leaghur）断层的空间位置。该批断层数据源自Macumber（1991）与Robson及Webb（2011）的研究成果，并完成了数字化处理。

这些呈南北走向的断层似乎截断或干扰了墨累盆地内的多处横切构造。其中欣德马什、蒂勒尔、阿沃卡和利厄断层均对现代河流径流产生影响；若第三纪（Tertiary period）期间断层曾持续活动，则该现象或可指示这些断层早前对含水层（aquifer）造成了影响。

本数据集由GHD编制，旨在为DEPI的"未来权益保障分配（Secure Allocation Future Entitlements, SAFE）"项目的报告《地质构造对地下水流动系统的潜在影响》（Potential Influences of Geological Structures on Groundwater Flow Systems）提供数据支撑。
