Sedimentology and Facies Distribution within the Horn Valley Siltstone, Amadeus Basin

Australian Ocean Data Network provides a reconnaissance study of the Horn Valley Siltstone formation in the Amadeus Basin. The dataset is based on sedimentological and palaeontological analysis from five fully cored wells, with the formation subdivided into ten informal members. Organic geochemical data from two wells confirm facies variations, including a transition layer with recorded TOC values up to 6.30%.

Use Cases

• Model vertical lithofacies variations in a shallow marine shelf environment based on described informal members.
• Correlate sedimentological features with organic matter preservation based on described oxygen and bioturbation controls.
• Identify high organic-rich sediment intervals based on the described shale to carbonate ratio transition and TOC values.

Strengths

• Analysis is based on fully cored material from five specific wells: Henbury #4, Henbury #6, Mt Liebig #2, Tempe Vale#1 and Tent Hill #1.
• Includes organic geochemical data confirming facies variations, with recorded TOC values of up to 6.30%.
• The formation is subdivided into ten informal members (HV1 to HV10) based on multiple sedimentological and palaeontological criteria.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, focusing solely on the Amadeus Basin.
