The map addresses the distribution of Archaean rocks of the central Eastern Goldfields of Western Australia. Interpretation was undertaken at 1:250 000 scale for both Geoscience Australia aeromagnetic data (400m linespacing) and Fugro Airborne Surveys Pty. Ltd. data (200m linespacing). The Archaean rocks are subdivided into undivided gneiss-migmatite-granite (Agmg), banded gneiss (Agn), greenstone (Aa), and granite plutons (Ag). Where important relative differences in magnetisation are mapped, the geophysical map units include the suffixes _h (high), _m (medium), _l (low) and _r (remanent) for the level of magnetisation. Dykes, faults, and unassigned small intrusives are also mapped. The map is derived from a subset of a more extensive interpretation covering the exposed extent of the Yilgarn Craton.
