Horn Valley Siltstone: Sedimentology and Facies Data from Cored Wells

Geoscience Australia Data 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 was used to confirm facies variations, including a high organic-rich transition with TOC values up to 6.30%.

Use Cases

• Classifying lithofacies variations in a shallow marine shelf environment based on described sedimentological and palaeontological information.
• Modeling the relationship between organic matter preservation and bottom water oxygen concentration based on the described geochemical inference.
• Identifying high organic-rich sediment intervals based on the described shale-to-carbonate ratio transition and TOC values.

Strengths

• Analysis is based on material from five fully cored wells (Henbury #4, Henbury #6, Mt Liebig #2, Tempe Vale#1, Tent Hill #1).
• Includes specific organic geochemical data points, such as a recorded TOC value of 6.30%.
• The formation is subdivided into ten informal members (HV1 to HV10) based on multiple 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 the specific cored wells in the Amadeus Basin.
