This dataset consists of a series of approximate WSW to ENE oriented 'geological structures' interpreted from residual gravity bedrock depth in the Goulburn-Murray area of Victoria. These structures segment the Goulburn River Valley into an upper, middle and lower Goulburn bedrock valley system suggesting that it is a broadening out upland groundwater system for most of its length. 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.

This dataset contains linear geological structure data not included in GEOL - this includes anticlines, synclines and bedding form surfaces. The data have been collected by the Geological Survey of Victoria. The dataset is accompanied by other datasets representing geological polygons and boundaries, miscellaneous lines, miscellaneous polygons, metamorphism, and placer deposits.

Geological structure measurements taken by Geological Survey of Victoria. Measurement methods - most of the structure measurements were collected in the field as part of the ongoing regional mapping program then entered into the corporate database. Measurements are taken using a geological compass. Surfaces are recorded as dip - dip direction. Lineations are recorded as plunge - azimuth. Declination measured to magnetic north then corrected to true north automatically within the database. A small amount of pre-1995 structural data has been digitised from previous maps. Field data is either recorded in a notebook in the field then typed into the database or recorded digitally in the field and automatically transferred into the database (this applies to the majority of data collected since 2002). Display - structural measurements have been divided into four categories to simplify display. Bedding contains measurements of sedimentary bedding where the bedding surface is upright, overturned or younging unknown. Foliation contains measurements of the commonly measured foliations seen in rocks such as cleavages etc. Folds contains measurements of structures directly associated with folds such as fold axis, axial surface etc. Other contains all other structural measurements including faults, joints, quartz vein orientations etc.

This dataset consists of geological faults interpreted from seismic data provided by the Department of Environment and Primary Industries (DEPI). 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.

This dataset contains interpreted geological data, both units underlying the basins and magnetic (mostly volcanic) units enclosed by the basin sediments. The linear features in the data set are geological boundaries, major faults, lesser faults and dykes. The onshore magnetic, radiometric, topographic and gravity data have been collected by the Geological Survey of Victoria. This has been supplemented by offshore magnetic and bathymetric data collected by the Australian Geological Survey Organisation and deep seismic data collected by the Australian Geological Survey Organisation and company sources. The map attempts to reconcile the onshore geology interpreted in Simons & Moore (1999) with the geophysical responses in a way that is geologically reasonable, and to carry this interpretation offshore at least as far as the Tasmanian sea boundary (generally 39 degrees 12 minutes South). The legend broadly uses the same time breaks as that of the Pre-Permian geological map, but includes younger packages that lie beneath the basin. No attempt has been made to subdivide granitic rocks of a particular age. The dataset is accompanied by other datasets representing lava flows and the basin edges. Lava flows have been interpreted either from intersections in drill holes or from magnetic responses. References: MOORE, D.H., 2002.

This dataset consists of geological faults for the Top Latrobe Group interpreted from industry seismic data compiled by the Department of Environment and Primary Industries (DEPI). 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.

This dataset comprises boreholes used as an input to bore controlled residual gravity to map bedrock depth, basement structure and as indicator of basal aquifer thickness variation in Victoria. These boreholes have been used to give better control for analysing Free Air (FA) gravity data. 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.
