Horn Valley Siltstone Sedimentology and Facies from Cored Wells

A reconnaissance study of the Horn Valley Siltstone formation in the Amadeus Basin, based on sedimentological and palaeontological data from five fully cored wells. The formation is subdivided into ten informal members reflecting lithofacies variations in a shallow marine shelf environment. Organic geochemical data from two wells was used to confirm facies variations, with recorded TOC values of up to 6.30%.

Use Cases

• Classifying lithofacies variations based on sedimentological and palaeontological information described in the study
• Modeling the relationship between oxygen concentration, bioturbation, and organic matter preservation as inferred in the description
• Identifying high organic-rich sediment intervals based on the shale-to-carbonate ratio transition mentioned between members HV6 and HV7

Strengths

• Defined ten informal members (HV1 to HV10) based on multiple sedimentological and palaeontological criteria
• Includes organic geochemical data with recorded TOC values of up to 6.30%
• Data sourced from five fully cored wells (Henbury #4, Henbury #6, Mt Liebig #2, Tempe Vale#1, Tent Hill #1)

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
