Geoscience Australia Data provides a report on seven areas of iron ore occurrences examined by Nevsam Mining Company Pty. Ltd. in October 1961. The report describes hematite rubble, gossanous lodes, surface enrichments, banded iron formation, magnetite schist, and a possible sedimentary hematite deposit. For one rubble area, it estimates between 30,000 and 40,000 tons of ferruginous material per vertical foot, with a probable depth not exceeding ten feet.
Use Cases
- Identify potential iron ore deposit types based on described occurrences like hematite rubble and gossanous lodes.
- Assess the scale of a specific ferruginous rubble deposit based on the tonnage per vertical foot estimate.
- Prioritize areas for further exploratory work based on the report's recommendations for the rubble and gossanous areas.
Strengths
- Report provides a specific tonnage estimate of 30,000 to 40,000 tons per vertical foot for one area.
- Document details seven distinct areas with different geological characteristics like hematite rubble and banded iron formation.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Data may reflect temporal bias inherent to a 1961 survey.
