NDI Carrara 1: Strontium, Carbon, Oxygen Isotope Data from a Stratigraphic Drill Hole

Strontium, carbon, and oxygen isotope measurements from carbonate samples collected from the NDI Carrara 1 stratigraphic drill hole. The data covers samples from the Paleozoic Georgina Basin and Proterozoic Lawn Hill Formation, intersecting a total depth of 1751 meters. The dataset was produced by Geoscience Australia as part of the MinEx CRC National Drilling Initiative to understand paleo-depositional environments and chemostratigraphy.

Use Cases

• Reconstructing paleo-depositional environments based on strontium, carbon, and oxygen isotope ratios.
• Identifying global chemostratigraphy trends by comparing isotope excursions to known Cambrian events.
• Assessing basin restriction and terrigenous influx using radiogenic strontium isotope values.
• Evaluating hydrocarbon resource potential through geochemical analysis of intersected rock units.

Strengths

• High-resolution strontium, carbon, and oxygen isotope data from a 1751-meter-deep drill hole.
• Samples cover both the Paleozoic Georgina Basin (~625 m) and Proterozoic sections (~1120 m).
• Data presented at a major scientific conference (2023 Australian Earth Science Convention).

Limitations

• The majority of samples show significant alteration, limiting assessment of primary depositional conditions.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
