SHRIMP zircon U-Pb ages were measured for the Browning intrusive Unit to examine the tectonic history of the Terra Nova Intrusive Complex in northern Victoria Land, Antarctica. The dataset likely contains geochronological measurements, including an igneous age of 503.8 ± 5.7 Ma for the Browning foliated leucogranite (SB171116-6C). It was provided by AMD_KOPRI and last updated in June 2021.
Use Cases
- Calibrate tectonic models for northern Victoria Land based on the reported igneous age.
- Compare crystallization ages of Antarctic leucogranites using the U-Pb measurement.
- Validate regional geological timelines using the specific age data point.
Strengths
- Includes a specific, precisely measured igneous age of 503.8 ± 5.7 Ma.
- Focuses on a specific geological unit (Browning foliated leucogranite) and location (Terra Nova Bay).
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
