Abstract
The 11GA-YO1 deep seismic reflection survey reveals information on the crust down to ~66 km depth, imaging the crust-mantle boundary. The seismic survey traverses the Yilgarn Craton, Officer Basin and Musgrave Province yielding information on their key structures and boundaries. Interpretation of the seismic reflection data was complimented with forward modelling and 3D inversion of gravity and magnetic data. This allowed the geological structures interpreted in the seismic data to be investigated and extended into 3D space. The 3D gravity and magnetic inversions shown here reveal information on the geology and structure of the crust in the Yilgarn-Officer-Musgrave (YOM) region. In particular, information on the nature of dipping bodies beneath the Officer Basin and the boundary between the Yilgarn Craton and Musgrave Province.
