Broken Hill Interpretive Mapping Project
The project aims to interpret the stratigraphy of the Proterozoic in the Broken Hill region. One of the products will be a revised stratigraphic map, based on the existing detailed GSNSW lithological mapping and the latest geophysics (gravity, magnetic, radiometric, SPOT, Landsat and ASTER data). The project will extend under cover and into Neoproterozoic sequences which surround the Curnamona Craton rocks. The interpretation will include regional structural components and use the latest stratigraphic nomenclature based on modern age dating.
A Broken Hill gravity survey covering 30 000 km2 from the Mundi Mundi Plain to the Victorian–South Australian border contributed data to the project. The survey covered the Broken Hill Block, Lock Lilly–Kars Belt and the interpreted southern extension of the Koonenberry Belt. It comprised nearly 4000 new gravity stations in the Broken Hill district on a 2 × 2 km grid, extending the existing high-precision gravity coverage over the world-renowned Broken Hill deposit and facilitating mineral exploration in the region.
The preliminary 1:100 000 interpretive map is available as a high-resolution rectified JPEG image.
This project is part of the Broken Hill Exploration Initiative (BHEI).
