A 479.0 ± 4.3 Ma igneous age measurement for the Abbott alkali feldspar granite (SB171116-1) was obtained. The data was collected from the Terra Nova Bay area in northern Victoria Land, Antarctica to examine the tectonic history of the Terra Nova Intrusive Complex. It was published by AMD_KOPRI and last updated on NASA EarthData in June 2021.
Use Cases
- Calibrate tectonic models for northern Victoria Land based on the reported igneous age.
- Compare crystallization ages of Antarctic granites using the specific U-Pb measurement.
- Validate regional geological timelines using the Abbott intrusive unit's dated age.
Strengths
- Provides a precise igneous age measurement of 479.0 ± 4.3 Ma.
- Focuses on a specific geological unit (Abbott alkali feldspar granite) and location (Terra Nova Bay).
Limitations
- Row count and column-level documentation are unknown.
- Last updated 2021-06-23; freshness should be verified.
- Data may reflect geographic bias inherent to nasa_earthdata.
