Strontium, Carbon, and Oxygen Isotope Data from NDI Carrara 1 Drill Hole

New high-resolution strontium, carbon, and oxygen isotope data from carbonate samples collected from the NDI Carrara 1 stratigraphic drill hole, completed in 2020. The data, presented by Geoscience Australia, covers the Paleozoic Georgina Basin and Proterozoic Lawn Hill Formation, aiming to improve understanding of paleo-depositional environments and chemostratigraphy in the Carrara Sub-basin. The analytical program was carried out following the drillhole's completion, with findings presented at the 2023 Australian Earth Science Convention.

Use Cases

• Assessing paleo-depositional environments based on strontium, carbon, and oxygen isotope ratios.
• Investigating local and global chemostratigraphy trends recorded in the Carrara Sub-basin.
• Correlating isotopic excursions with reported mid-Cambrian global marine events.
• Evaluating basin restriction and terrigenous influx using radiogenic strontium isotope values.

Strengths

• Data originates from a 1751-meter stratigraphic drill hole, providing a deep geological section.
• Includes isotope data from two distinct geological units: the Paleozoic Georgina Basin and the Proterozoic Lawn Hill Formation.
• Analytical program was conducted by the authoritative Geoscience Australia organization.

Limitations

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