Horn Valley Siltstone: Sedimentology and Facies Data from Cored Wells

The Amadeus Basin in Australia provides the core samples for this geological study. It subdivides the Horn Valley Siltstone formation into ten informal members based on sedimentological and paleontological features from five cored wells. The dataset includes organic geochemical data, with recorded TOC values of up to 6.30%, used to confirm facies variations.

Use Cases

• Modeling shallow marine shelf paleoenvironments based on described lithofacies variations.
• Correlating stratigraphic members across wells based on sedimentological and paleontological markers.
• Analyzing the relationship between bioturbation, oxygen levels, and organic matter preservation as inferred in the description.
• Identifying intervals with high organic content for resource assessment based on reported TOC values.

Strengths

• Data is derived from fully cored wells, which can provide well-preserved material where surface exposure is poor.
• The study defines ten distinct lithofacies members, providing a structured framework for analysis.
• Includes organic geochemical data with a specific, recorded TOC value of up to 6.30%.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset's primary format is PDF/HTML, which may require extraction for computational analysis.
