Full description
This solid geology map combines information from aeromagnetic and gravity interpretation by the author at 1:100 000 scale with that from outcrop geology to provide a continuous representation of the distribution of Palaeoproterozoic and Archaean rocks. The mapping of outcrop geology for Leonora 1:250 000 map sheet (2nd edition) was undertaken by Duggan, M.B., Williams, P.R., Jagodzinski, E.A., Rattenbury, M., Champion, D.C., Stewart, A.J., and Bastrakova, I.V., largely as part of the National Geoscience Mapping Accord (NGMA -1990 to 2000).Briefly, the data set and map, present geological boundaries/units, faults, fractures, folds, veins, dykes, joints, marker beds, trends, structural measurements, and mineral deposits.

Statement: The geological lines and polygons for the Leonora 1:250 000 solid geological map were drawn on film over plots of Total Magnetic Intensity (TMI), TMI first vertical derivative, Bouguer gravity, first vertical derivative of Bouguer gravity and outcrop geology at 1:100 000 scale, in GDA94 MGA51 datum and projection. The drawings on film were scanned and the resulting image digitised on screen using Microstation software. The digital lines and attributes were subsequently imported into ARC/INFO for complete attribution, editing and map composition.
