%X In 2011, Geoscience Australia collected 484 km of deep-crustal (22 second) seismic reflection data. The survey (11GA-YO1) traverses the north-eastern edge of the Yilgarn Craton, the Officer Basin and the western end of the Musgrave Province. The purpose of the seismic survey was to delineate broad crustal architecture and define the Moho, with particular interest in the Yilgarn-Musgrave boundary. To compliment the seismic survey, a 3D geological model was constructed that incorporates interpretations derived from seismic, potential field, surface geology and borehole data. Forward and inverse modelling techniques were applied to the potential field data to extrapolate the seismic interpretations into 3D space. Borehole data was used to constrain the interpretation of upper crustal sequences where available. The model was later used to constrain 3D potential field inversions of the area. This poster presents a 3D geological model of the YOM region as well as the geological and geophysical constraints that were used to construct it. Some of the fundamental and technical limitations of the model are also discussed.
