Geochemical and petrographic data from mafic volcanic rock samples collected in Palmer Land and Graham Land, Antarctica. The dataset includes field information, petrography, and raw geochemical measurements from multiple analytical techniques. It was produced by SCIOPS using archived material from the British Antarctic Survey, with data primarily from the 2001/02 period.
Use Cases
- Identify mantle domains and terranes beneath the Antarctic Peninsula using geochemical signatures from XRF and ICPMS data.
- Define crust/mantle architecture profiles by correlating field information with electron microprobe and Ar/Ar analysis results.
- Analyze the composition of subcontinental lithospheric mantle using primitive basalt dyke chemistry from TIMS measurements.
- Compare new and collated published geochemical data to model the history of asthenospheric domains.
Strengths
- Data integrates multiple analytical techniques (XRF, ICPMS, TIMS, Ar/Ar, Electron Microprobe).
- Includes both new measurements and collated published data for Antarctica.
- Samples sourced from archived material at the authoritative British Antarctic Survey.
Limitations
- Sample size and row count are unknown.
- Temporal coverage is limited, with last update in February 2002.
- Geographic scope is restricted to Palmer Land and Graham Land within the Antarctic Peninsula.
