River Sediment Geochemistry and Weathering Analysis for Madagascar

Raw chemical element content data and weathering condition analysis for river sediment samples from Madagascar. The dataset supplements a 2023 manuscript submitted to the Journal of Geophysical Research-Earth Surface by researchers from ETH Zurich. Commercially sensitive data is hidden but available upon request from the corresponding author.

Use Cases

• Calculating chemical weathering indices based on sediment geochemistry data.
• Analyzing the relationship between weathering and escarpment morphology described in the manuscript.
• Modeling rates of landscape change in rift margin settings using provided geochemical proxies.

Strengths

• Includes raw chemical element content data for sediment samples.
• Accompanied by an open-access MATLAB code for calculating weathering indices.
• Directly supports a peer-reviewed manuscript submitted to a major geoscience journal.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Commercially sensitive data is redacted, requiring direct contact with the author for full access.
