Ferrar Dolerite Geochemical and Paleomagnetic Samples from Antarctica

A suite of geological samples from the Transantarctic Mountains provides data for paleomagnetic and geochemical analysis. The collection, housed at the University of Otago, includes oriented paleomagnetic samples and approximately 300 kg of rock sampled per field season. This data was published by SCIOPS and last updated in early 2007.

Use Cases

• Determine magma flow directions by analyzing oriented paleomagnetic sample data combined with field observations.
• Model the emplacement history of the Ferrar Large Igneous Province using geochemical analysis results from rock samples.
• Correlate paleomagnetic pole positions with other Jurassic datasets using oriented sample measurements.
• Study upper crustal magma chamber processes by integrating geochemical data with sample location and field context.

Strengths

• Sample collection includes oriented paleomagnetic specimens, a key feature for flow direction analysis.
• Rock samples are substantial, averaging 1 kg each, allowing for multiple analytical techniques.
• Collection effort was significant, with about 300 kg of rock sampled per field season.

Limitations

• The dataset's size in terms of rows, columns, and specific sample count is unknown.
• Data is temporally stale, with the last update recorded in January 2007.
• Geographic scope is limited to specific sites within the Transantarctic Mountains.
