Indian Ocean Magnetic Anomaly Picks for Tectonic Rotations

Magnetic anomaly and fracture zone picks from the Indian Ocean used to calculate Euler rotations for tectonic plates. The data set includes picks for 14 time intervals between Chrons 29o and 13o from four major ocean ridge systems. It was created by SCIOPS and used in the publication by Cande et al. (2010).

Use Cases

• Calculate Euler rotations and their uncertainties using the provided latitude, longitude, and uncertainty estimate fields.
• Model plate motions for Antarctica, Indian, and African plates simultaneously using the organized plate and segment data.
• Analyze tectonic constraints by comparing different data combinations, such as including or omitting Carlsberg ridge picks.
• Validate plate rotation models using the included output files from the Hellinger software programs.

Strengths

• Data covers 14 distinct time intervals between Chrons 29o and 13o.
• Includes picks from four major Indian Ocean ridge systems.
• Provides up to four different constraint combinations for each time interval for analysis.

Limitations

• The exact number of data points (rows) is not specified.
• Data is specific to the early Cenozoic era and may not reflect modern configurations.
• Relies on the specific input format of the Hellinger software, which may require adaptation.
