Geological Fault and Fold Systems in Papua New Guinea from Airphoto and Radar Surveys

A discussion document from 1971 presents corrected geological data for Papua New Guinea. It critiques a prior publication's inaccuracies regarding lineaments and fault systems, such as the omission of the Owen Stanley and Frieda faults. The Bureau of Mineral Resources and the Geological Survey of Papua New Guinea compiled this data through ground surveys, airphoto analysis, and side-looking airborne radar imagery over the preceding 5-25 years.

Use Cases

• Validate and correct historical geological maps based on the described ground and remote sensing surveys.
• Study the distribution and classification of major faults and folds in Papua New Guinea referenced in the text.
• Analyze the use of airphoto and side-looking radar imagery for geological feature detection as described in the methodology.

Strengths

• Data is based on exhaustive examinations of airphotos at scales from 1:20,000 to 1:80,000 and side-looking airborne radar imagery.
• Findings are supported by extensive field mapping by government and oil exploration company geologists over 25 years.
• Specifically identifies and corrects omissions of major faults like the Owen Stanley and Frieda faults from a prior publication.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary document is a discussion from 1971; freshness should be verified against modern data.
