This dataset comprises geological rock units, boundaries, structural observations and alteration/metamorphic zones. The dataset has been compiled from geological reports, existing 1:25,000, 1:50,000 and 1:63,360 scale mapping, new field mapping and interpretation of aerial photography and airborne geophysical data. It has been compiled to fit the Land Information System Tasmania (LIST) digital topographic base. Additional information about the source and reliability of the geological data has also been captured.
The dataset currently covers around 40% of Tasmania and the capture of new data is ongoing. To see the areas that are currently mapped at this scale, or to download map sheet images please refer to the Digital Geological Atlas 1:25,000 Scale Series map index.
