Description
Three printed map sheets (Rowley Shoals, Scott Reef, and Arafura Sea) by early 1974, with two further sheets in progress, document the systematic reconnaissance geological survey of the continental shelf initiated by the Bureau of Mineral Resources. The results are published in the BMR Bulletin series, accompanied by 1:1,000,000 lithofacies maps of the shelf sediments. Users should refer to Bulletin 83 (GeoCat #163) for interpretation, as the map does not distinguish between modern sediments and relics of earlier depositional regimes.
Use Cases
Analyze sediment lithofacies distribution across the continental shelf based on the 1:1,000,000 scale maps.
Study non-depositional or erosional areas of the shelf as indicated in the map description.
Infer the distribution of older sediment regimes by cross-referencing the map with Bulletin 83 and studying gravel content in relation to bathymetry.
Strengths
Part of a systematic reconnaissance program by the Bureau of Mineral Resources, suggesting an organized survey methodology.
Includes three specific, printed map sheets (Rowley Shoals, Scott Reef, Arafura Sea) with a defined 1:1,000,000 scale.
Associated with published bulletins (e.g., Bulletin 83) that provide interpretive context for the maps.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment.
The map does not distinguish between modern sediments and relics of earlier depositional regimes, requiring supplemental study.
Provenance
Source
Bureau of Mineral Resources (BMR), published in the BMR Bulletin series.
Collection Method
Systematic reconnaissance geological surveys of the continental shelf.
Time Range
Surveys initiated after 1967; map sheets printed by early 1974.
Freshness
Last updated 2026-06-23 05:55:00.794027; freshness should be verified.
Geography
Timor Sea continental shelf, including specific areas like Rowley Shoals (W.A.), Scott Reef (W.A.), and Arafura Sea (N.T.).
File formats are HTML and PDF, which may require specific tools for geospatial analysis; the primary data is likely map imagery rather than tabular data.
