Abstract
This data set was compiled to provide geological context for the 2001 seismic reflection line acquired between Leonora and the northwest Neale 1:250 000 sheet. The data set includes reviewed solid geology for the Leonora (Blewett) and Laverton (Whitaker) 1:250 000 sheets but also includes 1:100 000 sheets for northeast Menzies and northern Edjudina 1:250 000 sheet areas as well as aeromagnetic interpretation of the Rason and Neale 1:250 000 sheets. Archaean rocks of the Eastern Goldfields Province of the Yilgarn Craton form basement to the area traversed in the seismic survey. In the west, granite and abundant greenstone of the Norseman-Wiluna Belt are dislocated by major north-northwest to north oriented shear zones. East of the Norseman-Wiluna Belt, the crust is dominated by granitic lithologies with shear zones and greenstone in much lower abundance. Gneiss of the Proterozoic Albany-Fraser Province abuts the Yilgarn Craton about 50 km to the east of the eastern end of the seismic line.

Lineage
The lines and polygons of the solid geology (Leonora, Laverton, Menzies-part, Edjudina-part) were drawn on film overlayed on images of aeromagnetics (TMI), first vertical derivative of the aeromagnetics (TMI1vd), gravity, and aeromagnetics with outcrop geology at 1:100,000 scale. Lines and polygons of the edge-matched aeromagnetic interpretation (Rason and Neale) were drawn on film overlaying Images of TMI, TMI1vd, or contour plots of TMI at 1:250 000 scale. The film drawings were subsequently scanned, digitised on screen and attributed.
