Research data from the Fosdick migmatite-granite complex in West Antarctica's Ford Ranges investigates Paleozoic and Mesozoic orogenic cycles. The dataset includes fieldwork, structural geometry, petrology, and geochemical analysis from four traverse sites. It was produced by AMD_USAPDC and last updated in 2013.
Use Cases
- Model P-T-t trajectories from crustal thickening/thinning using mineral equilibria modeling data.
- Analyze mantle contributions by examining geochemical and isotopic data from sampled mafic plutonic phases.
- Study melt flow networks through petrological associations and microstructures of host gneisses and leucogranites.
- Reconstruct orogenic cycles by correlating structural geometry data with in situ mineral dating results.
- Investigate crustal evolution by integrating geochronology data with source rock and granite product analyses.
Strengths
- Data covers four distinct field traverse sites within the complex.
- Integrates multiple geological disciplines: fieldwork, structural geology, petrology, geochronology, and geochemistry.
Limitations
- Dataset size, row count, and specific file formats are unknown.
- Data is from 2013 and may not reflect more recent findings.
- Geographic scope is limited to the northern Ford ranges in Marie Byrd Land.
