Antarctica's Terra Nova Bay area provides zircon U-Pb age data for a mylonitic paragneiss sample (SB171127-1D). The dataset likely contains detrital and metamorphic ages measured to examine the tectonic history of the Terra Nova Intrusive Complex in northern Victoria Land. It was contributed by AMD_KOPRI and last updated in June 2021.
Use Cases
- Determine the timing of metamorphic events based on the 530-490 Ma metamorphic age range mentioned in the description.
- Analyze provenance and sediment source regions based on detrital zircon ages.
- Model tectonic history of the Terra Nova Intrusive Complex based on the stated purpose of the data.
- Correlate geological events across northern Victoria Land based on zircon age data from the Gerlache Inlet Shear Zone.
Strengths
- Focuses on a specific geological sample (SB171127-1D) from a defined location.
- Includes a reported metamorphic age range of 530-490 Ma.
- Data originates from a research organization (AMD_KOPRI).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
