Antarctica's northern Ford Ranges contain data from a study of the Fosdick migmatite-granite complex, investigating Paleozoic and Mesozoic orogenic cycles. The dataset includes results from fieldwork, structural analysis, petrology, mineral equilibria modeling, geochronology, and geochemistry. It was produced by the AMD_USAPDC organization and last updated in 2014.
Use Cases
- Model P-T-t trajectories from orogenic cycles using mineral equilibria data and in situ mineral dating results.
- Analyze mantle contributions by examining geochemical and isotopic data from sampled mafic plutonic phases.
- Investigate melt migration patterns using structural geometry and microstructure data from host gneisses and leucogranites.
- Correlate crustal differentiation events with geochronological data from detailed sampling at four traverse sites.
Strengths
- Focuses on a specific, well-defined geological complex in the northern Ford Ranges.
- Integrates multiple analytical methods including geochemistry, geochronology, and structural geology.
Limitations
- Specific data volume, row count, and column details are unknown.
- Data is from 2014 and may not reflect the most recent research or analytical techniques.
- Geographic scope is limited to four specific traverse sites within the Fosdick complex.
