Granulite Pressure-Temperature-Time Paths From Northern Prince Charles Mountains

Metadata describes a study of felsic to mafic granulites and charnockite intrusions in the Porthos Range of east Antarctica. The data originates from ASAC Project 123, managed by the Australian Antarctic Data Centre (AU_AADC). The record was last updated in March 1995.

Use Cases

• Analyze pressure-temperature-time (P-T-t) paths for granulites to model crustal evolution.
• Correlate trace element patterns, such as normalized REE profiles, with modern arc or subduction zone settings.
• Study the chemical relationship between charnockite intrusions and host granulites using major and trace element data.
• Investigate protolith origins using geochemical indicators like K/Rb ratios to assess fractionation processes.

Strengths

• Study integrates metamorphic, structural, and geochronological data for a holistic analysis.
• Focus on a specific, well-defined geological region: the Porthos Range in the Northern Prince Charles Mountains, Antarctica.

Limitations

• Dataset is metadata only; the underlying research data files, formats, and size are unknown.
• Temporal coverage is limited to a late Proterozoic geological event, with no recent updates since the 1995 record.
