Cenozoic Geology Layer of Western Australia at 1:500,000 Scale

2026 update to the 1:500,000 State Cenozoic geology layer for Western Australia, compiled from published geological maps and modified using geophysical datasets. This layer depicts Cenozoic paleovalleys and significant Cenozoic bedrock areas overlying pre-Cenozoic geology. It is part of a three-layer digital bedrock geology compilation.

Use Cases

• Map Cenozoic paleovalleys and bedrock extents using the Cenozoic geology layer for landscape evolution studies.
• Integrate the Cenozoic layer with the linear structures layer to analyze structural relationships with younger geological units.
• Use the Cenozoic geology layer as a base for mineral exploration targeting in areas of significant Cenozoic cover.

Strengths

• Compilation is based on published Geological Series maps at scales from 1:100,000 to 1:1,000,000.
• Data incorporates modifications from geophysical datasets (magnetics, radiometrics, gravity), remote sensing imagery, seismic profiles, and drilling.
• Part of a three-layer digital geology system including interpreted bedrock geology, Cenozoic geology, and linear structures.

Limitations

• The Cenozoic geology layer has no current updates from its 2016 revision, potentially missing recent discoveries.
• Sample data and specific attribute columns are unavailable for detailed review of data structure.
• Linear structures layer primarily refers to pre-Cenozoic structures, limiting direct analysis of Cenozoic structural features.
