Horn Valley Siltstone: Sedimentology and Facies Data from Cored Wells

The Horn Valley Siltstone dataset from the Australian Ocean Data Network contains sedimentological and palaeontological data from five cored wells in the Amadeus Basin. It subdivides the formation into ten informal members based on lithology, bedding types, fossil presence, and bioturbation. Organic geochemical data from two wells confirm facies variations, with recorded TOC values up to 6.30%.

Use Cases

• Classify lithofacies variations based on sedimentological and palaeontological criteria described.
• Model organic matter preservation based on oxygen concentration and bioturbation factors discussed.
• Correlate stratigraphic members across wells using the defined HV1 to HV10 member framework.
• Analyze the relationship between shale-to-carbonate ratio shifts and high organic content, as noted at the HV6-HV7 transition.

Strengths

• Data is derived from five fully cored wells, providing direct subsurface observations.
• Includes organic geochemical data with specific TOC measurements up to 6.30%.
• Formal subdivision into ten members based on multiple sedimentological and palaeontological criteria.

Limitations

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