The lineament interpretations were used to target mineral exploration, famously including the analysis that led to the discovery of the Olympic Dam deposit in South Australia. Papers discussing the lineament approach are collected in Bourne & Twidale (2007). Lineaments were interpreted from a range of data available at the time, including magnetic and gravity maps, topography, standard geological maps, and 'chicken track'interpretation of aerial photographs and early satellite images. This product comprises high quality digital scans of 130 of the original paper maps, rectified and georeferenced for use in GIS software. Geoscience Australia reproduces these maps and makes them available publicly for their historic and scientific interest. The paper originals are held in the Geoscience Australia library. {"type": "Polygon", "coordinates": [[[100.0, -40.0], [160.0, -40.0], [160.0, 0.0], [100.0, 0.0], [100.0, -40.0]]]} 100.0 160.0 -40.0 0.0 GIS Dataset Geology Published_External File download documentDigital Download the map package (jpg) ZIP Unnamed resource documentDigital HTML
