Mount Chambers
South Australia, Flinders Ranges, Australia
Mississippi Valley TypeZn-Pb
- Type
- Carbonate-hosted sulfide Zn-Pb
Flinders Ranges, the deformed and uplifted northern Adelaide geosyncline, hosted in Neoproterozoic to Cambrian carbonates. Highly radiogenic lead, anomalous relative to the Holmes-Houtermans and Stacey-Kramers models, attributed to the U- and Th-rich basement; nonsulfide and sulfide deposits fall on one line, hence genetically related.
