High-temperature characteristic remanent magnetization components of Early Cretaceous and

82 high-temperature characteristic remanent magnetization (ChRM) directions were isolated from volcanic rocks on Snow Island, Antarctica. The data comprises 26 directions from Early Cretaceous rocks and 56 from Paleocene rocks. The dataset was authored by Hou Lifu and last updated in April 2026.

Use Cases

• Modeling paleomagnetic pole positions based on the isolated high-temperature ChRM components.
• Correlating volcanic sequences in the South Shetland Islands based on magnetic stratigraphy.
• Investigating geomagnetic field behavior during the Early Cretaceous and Paleocene periods.
• Supporting tectonic reconstructions of the Antarctic Peninsula using rock magnetization data.

Strengths

• Includes 82 total high-temperature ChRM directions, providing a substantive sample size.
• Data is split into two distinct geological periods: 26 Early Cretaceous and 56 Paleocene samples.
• Components were isolated via systematic stepwise thermal demagnetization, a standard methodology.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for some statistical methods.
• The dataset is small at 50.3 KB, indicating limited scope.
