Timor Sea Continental Shelf Sediments Map from BMR Bulletin Series

Geoscience Australia Data provides a series of 1:1,000,000 lithofacies maps of continental shelf sediments. The maps result from systematic reconnaissance geological surveys initiated by the Bureau of Mineral Resources following a 1967 monograph. Three map sheets covering Rowley Shoals, Scott Reef, and the Arafura Sea were printed by early 1974.

Use Cases

• Analyze sediment lithology variations across the continental shelf based on the described lithofacies maps.
• Study non-depositional and erosional shelf areas mentioned in the description.
• Investigate the relationship between gravel content and bathymetry as suggested in the description.
• Distinguish between modern and relict sediment regimes using the referenced Bulletin 83.

Strengths

• Maps are published at a 1:1,000,000 scale.
• Three specific map sheets (Rowley Shoals, Scott Reef, Arafura Sea) are identified as published by early 1974.
• Work is described as part of a systematic reconnaissance program initiated by the Bureau of Mineral Resources.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The map does not distinguish modern sediments from relict ones, requiring consultation of supplemental Bulletin 83.
• Row count is unknown, which may limit suitability assessment.
