501.5 ± 3.6 Ma is the igneous age reported for the Browning foliated biotite granite (J-58). The dataset contains SHRIMP zircon U-Pb ages measured to examine the tectonic history of the Terra Nova Intrusive Complex in northern Victoria Land, Antarctica. It was contributed by AMD_KOPRI and last updated in June 2021.
Use Cases
- Calibrate regional tectonic models based on the reported igneous age.
- Compare crystallization ages of Antarctic granites using the U-Pb data.
- Validate geological mapping of the Terra Nova Bay area with precise age constraints.
Strengths
- Provides a precise igneous age of 501.5 ± 3.6 Ma.
- Focuses on a specific geological unit (Browning foliated biotite granite J-58) in a defined Antarctic location.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
