Papua New Guinea Fault and Fold Systems from Geological Surveys

Wellman's 1971 data on Pacific fault systems is challenged as erroneous for Papua New Guinea. The dataset likely contains maps and discussion of major faults and folds identified by the Bureau of Mineral Resources and Geological Survey of Papua New Guinea over 25 years of field mapping and remote sensing. It includes figures correcting omissions like the Owen Stanley Fault and disputing the existence of a 'New Guinea Fault'.

Use Cases

• Validate and correct historical geological maps based on the described ground and remote sensing surveys.
• Study fault and fold system classification in Papua New Guinea using the referenced figures and maps.
• Analyze the use of airphoto and side-looking airborne radar imagery for geological lineament detection.
• Compare disputed fault interpretations, such as the 'New Guinea Fault', with established geological data.

Strengths

• Based on over 25 years of field mapping by government and oil exploration company geologists.
• Incorporates data from airphoto and side-looking airborne radar imagery analysis at scales from 1:20,000 to 1:80,000.
• Produced by authoritative bodies including the Bureau of Mineral Resources and the Geological Survey of Papua New Guinea.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data format is PDF/HTML, which may require extraction for computational analysis.
