NDI Carrara 1 is a 1751-meter stratigraphic drill hole completed in 2020 in the South Nicholson region of Australia. The dataset presents high-resolution strontium, carbon, and oxygen isotope data from carbonate-bearing samples of the Paleozoic Georgina Basin and Proterozoic Lawn Hill Formation. The analytical program was carried out by Geoscience Australia, MinEx CRC, and the Northern Territory Geological Survey.
Use Cases
- Assessing paleo-depositional environments based on strontium, carbon, and oxygen isotope ratios.
- Analyzing local and global chemostratigraphy trends recorded in the Carrara Sub-basin.
- Investigating basin connectivity to the global Cambrian ocean using strontium isotope ratios.
- Identifying positive carbon isotope excursions that may coincide with global marine events.
Strengths
- Data originates from a 1751-meter stratigraphic drill hole, providing a deep geological profile.
- High-resolution isotope measurements for three distinct elements (strontium, carbon, oxygen).
- Analytical program conducted by Geoscience Australia, MinEx CRC, and the Northern Territory Geological Survey.
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.
