Australian Heat Flow Measurements and Regional Contour Maps

Australian continent heat flow data, combining 20 new values with published land and marine data from the area 90-170°E, 0-45°S. Geoscience Australia Data produced contour maps of heat flux, revealing a generally low (30-60 mW m^-2) but regionally higher (70-100 mW m^-2) pattern in eastern Australia. The data was last updated on 2026-04-30.

Use Cases

• Modeling regional geothermal energy potential based on heat flux values.
• Correlating heat flow with seismic velocity anomalies (P-wave residuals, upper-mantle velocity) mentioned in the description.
• Investigating crustal evolution and craton boundaries based on the described heat-flow regimes.
• Creating or validating geospatial contour maps of subsurface thermal properties for Australia.

Strengths

• Includes 20 new heat-flow measurements combined with published data for broader coverage.
• Provides specific quantitative ranges for low (30-60 mW m^-2) and high (70-100 mW m^-2) heat-flow regions.
• Data is associated with a specific geographic bounding box (90-170°E, 0-45°S).

Limitations

• Data distribution is described as 'not good enough to delineate accurately the 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.
