New U-Pb Zircon Ages for 25 Victorian Granites, 493.8-365.7 Ma

New U-Pb zircon geochronology data from 25 granitoid rock samples collected across Victoria, Australia. The work was undertaken by Geoscience Australia's Exploring for the Future program to address a relative dearth of modern geochronology in the state. The final sample set represents a 25% increase in the U-Pb zircon geochronology coverage of Victoria.

Use Cases

• Modeling the tectono-stratigraphic evolution of Victoria based on the ten named tectonic zones.
• Calibrating regional geological maps and cross-sections based on new granite ages.
• Comparing the timing of magmatic events across different tectonic zones like the Glenelg, Bendigo, and Omeo zones.
• Integrating new age constraints into crustal evolution models for the Lachlan Orogen.

Strengths

• Provides new ages for 25 granitoid rock samples, representing a 25% increase in U-Pb zircon coverage for Victoria.
• Samples span all ten tectonic zones in Victoria, offering broad spatial coverage.
• Ages are precisely dated, ranging from 493.8 to 365.7 million years ago.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided as a PDF report, which may require extraction for computational analysis.
