Passo Feio Complex U-Pb Zircon Data for Polyphasic Origin Analysis

Matheus Ariel Battisti's dataset from figshare, last updated April 2026, provides integrated U-Pb detrital zircon data from the Passo Feio Complex in Southern Brazil. The 15.4 MB collection includes five new samples and analysis of three main source patterns to constrain the complex's depositional history. It contains XLSX, PNG, JPG, and DOCX files.

Use Cases

• Modeling sedimentary provenance based on described Paleoproterozoic–Paleoarchean, Mesoproterozoic–Eoarchean, and Ediacaran–Neoarchean zircon age patterns.
• Correlating depositional sequences to tectonic blocks like the Nico Pérez or São Gabriel blocks as mentioned in the description.
• Investigating chronocorrelation between Sequence 2 and the Camaquã Basin based on the 630–580 Ma age range.
• Studying the 565 Ma tectonometamorphic event's impact on basin evolution as referenced in the dataset description.

Strengths

• Includes five new U-Pb detrital zircon samples for integrated analysis.
• Defines three distinct source patterns with specific age ranges (e.g., 1.7–3.5 Ga, 0.58–2.8 Ga) and peaks.
• Proposes correlations to specific crustal blocks (e.g., Nico Pérez, Congo, Kalahari) and basins.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description focuses on geological interpretation; raw data structure requires manual inspection.
