Evidence of Exhalative Origin for Cobar District Deposits

Evidence is presented for mineralogical zoning in seven deposits of the Cobar-Nymagee area. The deposits are contained in distal turbidite facies of the Devonian Cobar Supergroup, deposited in a meridional trough. The dataset is hosted by the Australian Ocean Data Network and was last updated on 2026-04-16.

Use Cases

• Analyzing mineralogical zoning patterns based on the described chalcopyrite-pyrrhotite and pyrite-sphalerite-galena sides
• Modeling the relationship between sedimentary-exhalative deposits and regional tectonics based on the proposed growth fault and rift concept
• Identifying potential mineralised horizons in the CSA mine based on the syn-sedimentary exhalative concept

Strengths

• Description details mineralogical zoning in seven specific deposits
• Description provides a geological context linking deposits to the Devonian Cobar Supergroup and regional tectonics

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
