Triassic Seismic Horizon and Fault Maps for the Central North West Shelf

Geoscience Australia conducted a regional mapping program targeting stratigraphic and structural exploration risk in the Triassic succession of the Roebuck Basin. The data pack includes seismic horizon grids and isochron grids generated from three key seismic horizons: TR10.0_SB, TR17.0_SB, and J10.0_SB. Fault maps compiled at the TR10.0_SB and J10.0_SB horizons are also included.

Use Cases

• Model subsurface basin structure based on mapped seismic horizons.
• Analyze stratigraphic intervals and depositional history using the provided isochron grids.
• Assess exploration risk by integrating fault maps with other geological data.
• Correlate seismic data with well logs using the synthetic seismogram tie mentioned in the description.

Strengths

• Data is derived from a combination of 2D and 3D seismic surveys, including named regional deep surveys.
• Horizons are placed within a defined regional tectonostratigraphic framework.
• Includes multiple data products: horizon grids, isochron grids, and fault maps.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
