Carbonate-hosted asbestos occurrences in South Australia: review of geology and implications for mesothelioma
- Hendrickx, Marc
DOIAbstract
Stratigraphic units with the potential for carbonate-hosted asbestos account for <3% of the land area of South Australia. Known asbestos occurrences are small, low grade and commonly weathered. The main mode of occurrence is as cross-fibre and slip-fibre veins of asbestiform magnesio-riebeckite (AMR) in metasomatised dolomites, and fibrous tremolite associated with talc mineralisation in the Adelaide Geosyncline. Small occurrences of chrysotile asbestos are hosted by dolomites in the Hutchison Group in the eastern Gawler Craton. Hyperspectral mapping could be used to locate additional asbestos mineralisation. Disturbance of natural asbestos-bearing materials in South Australia has been through mining, agriculture and natural weathering proc...
