Beltana
South Australia, Flinders Ranges, Australia
OtherZn (Pb)
- Type
- Hypogene nonsulfide zinc deposit (willemite)
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.
