1751-meter stratigraphic drill hole NDI Carrara 1 intersected Paleozoic and Proterozoic rocks in the Carrara Sub-basin. High-resolution strontium, carbon, and oxygen isotope data from carbonate samples aim to improve understanding of paleo-depositional environments. The dataset was presented at the 2023 Australian Earth Science Convention.
Use Cases
- Analyze paleo-depositional environments based on strontium, carbon, and oxygen isotope ratios
- Study local and global chemostratigraphy trends recorded in the Carrara Sub-basin
- Assess the connection of sampled intervals to the global Cambrian ocean based on 87Sr/86Sr ratios
- Identify potential mid-Cambrian positive δ13C global marine excursions from the isotope data
Strengths
- Data originates from a 1751-meter stratigraphic drill hole completed in 2020
- High-resolution isotope measurements for three elements (Sr, C, O)
- Samples cover both Paleozoic Georgina Basin (~625 m) and Proterozoic Lawn Hill Formation (~1120 m) sections
Limitations
- The majority of samples show significant alteration, limiting assessment of primary conditions
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
