East African Rift Extension and Fault Data with R Analysis Package

Supplementary files for a structural geology paper on the East African Rift System. The data includes tables for rift segment characteristics, a spreadsheet for computing extension obliquity, and an R package for generating compass face visualizations. The dataset was authored by Anne Frayssignes and last updated on April 30, 2026.

Use Cases

• Calculate extension obliquity for different rift segments and dates based on the provided spreadsheet.
• Analyze rift segment characteristics and structural inheritance based on the detailed type tables.
• Generate compass face visualizations for rift reference points using the included R package and source code.
• Reproduce and extend the geospatial analysis from the associated research paper.

Strengths

• Includes an R package with source code, input files, and output images for reproducible analysis.
• Provides a dedicated spreadsheet tool for computing a specific geophysical metric (extension obliquity).
• Data is directly supplementary to a peer-reviewed research paper on a major geological system.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and overall data scale are unknown, which may limit suitability assessment.
• The description metadata is limited; actual data quality requires manual inspection of the files.
