Mars CRISM Spectral Data for Carbonate and Clay Mineral Detection

Jeremy Brossier's supporting dataset for a 202x study investigates carbonate signatures on Mars. It includes shapefiles and tables for 540 CRISM targeted observation cubes, with attributes like absorption band centers and classification indexes. The data compiles mineralogical phases and includes terrestrial carbonate analogues from referenced studies.

Use Cases

• Classifying carbonate detection strength based on the Carb1 index (BD25) values for 540 cubes.
• Mapping tentative carbonate signatures using the Carb2 index (BD35) values for 418 cubes.
• Analyzing the correlation between mineralogical phases and spectral absorption band centers at 2.3, 2.5, and 3.5 µm.
• Comparing Martian spectral data with terrestrial carbonate analogues listed in Table S2.

Strengths

• Includes data for 540 CRISM observation cubes analyzed with the Carb1 index.
• Provides specific absorption band depth thresholds (e.g., BD25 > 2% for 'Strong' signature) for classification.
• Licensed under CC-BY-4.0, permitting sharing and adaptation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the primary tables is unknown, which may limit suitability assessment.
