Australian Heat Flow Measurements with Regional Contour Maps

Twenty new heat-flow values from sites across Australia are combined with published land and marine data. The data is used to produce contour maps of heat flux for the region 90-170°E, 0-45°S. The dataset is provided by Geoscience Australia Data and was last updated in April 2026.

Use Cases

• Modeling geothermal gradients based on measured heat-flow values.
• Correlating heat flow with seismic velocity anomalies based on the described P-wave travel-time residuals.
• Delineating geological provinces and craton boundaries based on regional heat-flow patterns.
• Assessing geothermal energy potential in eastern Australia based on the higher heat-flow values (70-100 mW m^-2).

Strengths

• Includes twenty new heat-flow measurements from widely separated sites.
• Combines new data with published land and marine data for a broader regional analysis.
• Identifies distinct heat-flow regimes, such as low (40-50 mW m^-2) in the Canning Basin and high (70-100 mW m^-2) in eastern Australia.

Limitations

• Data distribution is described as not good enough to accurately delineate boundaries of heat-flow regimes.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
