Geological Report on Bauxite Deposits in Manus Island, Papua New Guinea

Manus Island in Papua and New Guinea is the subject of a geological reconnaissance report describing nodular bauxite deposits. The report details three separate surface occurrences derived from volcanic rocks, likely of Miocene or younger age, and includes chemical analyses of individual nodules. The document was published by Geoscience Australia Data and was last updated on 2026-03-25.

Use Cases

• Identifying potential bauxite exploration targets based on described surface occurrences and favorable conditions.
• Studying the relationship between volcanic geology and bauxite formation based on the described parent rock types.
• Analyzing regional bauxite distribution based on the suggestion that deposits may be widespread, particularly in the west of the island.

Strengths

• Report includes chemical analyses showing high available alumina content in nodules from two deposits.
• Provides specific geological context, linking bauxite to recent volcanic rocks overlying a plutonic basement.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au.
