Stable carbon and hydrogen isotopic compositions of Paleozoic marine crude oils from the C

17 Paleozoic marine crude oil samples from the Canning Basin, Western Australia, analyzed for stable carbon (13C) and hydrogen (D) isotopic compositions of bulk, saturated, and aromatic hydrocarbons. The dataset, sourced via the Australian Ocean Data Network, compares these oils to other Australian and global marine oils to track isotopic changes throughout the Paleozoic era. The data has been used to refine the characterization of oil families and petroleum systems.

Use Cases

• Modeling source rock facies variations based on carbon and hydrogen isotopic profiles of individual n-alkanes.
• Assessing the level of thermal maturation attained by source rocks using isotopic data.
• Refining the characterization of oil families and petroleum systems within sedimentary basins.
• Comparing isotopic trends in Paleozoic marine oils across different basins and geological periods.

Strengths

• Focuses on 17 specific Paleozoic marine crude oil samples from the Canning Basin.
• Includes isotopic data for bulk, saturated, and aromatic hydrocarbon fractions, as well as individual n-alkanes.
• Provides comparative analysis with oils from other Australian basins (e.g., Arafura, Bonaparte, Perth).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, focusing on Western Australian basins.
