Brief 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.
