Crato Formation Geochemical Analyses for Chemostratigraphy, Brazil

The Araripe Basin in Brazil contains the Cretaceous Crato Formation, a fossil-rich deposit. Leonardo Corecco presents preliminary geochemical analyses of 25 limestone samples from five quarries in Nova Olinda and Santana do Cariri. The data includes major and trace element concentrations and enrichment factor calculations.

Use Cases

• Developing chemostratigraphic markers for fossil provenance based on elemental concentrations.
• Analyzing geochemical variations within limestone layers based on Zn and Cu content.
• Investigating the influence of geological faults on geochemical signatures.
• Correlating stratigraphic layers across different quarries using enrichment factor calculations.
• Supporting forensic paleontology efforts to relocate illegally collected fossils.

Strengths

• 25 geochemical samples analyzed from five distinct quarries.
• Includes major and trace element concentrations and enrichment factor calculations.
• Proposes two preliminary chemostratigraphic markers: elevated Zn and low Cu.
• Data is openly licensed under CC-BY-4.0.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
