Australian Ocean Data Network provides a dataset demonstrating the application of small angle neutron scattering (SANS) for determining hydrocarbon transport onset in shaly source rocks. The data includes results from laboratory pyrolysis of rocks containing marine Type II organic matter at temperatures between 310-370°C and a comparison with a natural maturity sequence. The dataset was last updated on 2026-05-05.
Use Cases
- Correlating neutron scattering intensity changes with hydrocarbon generation onset based on the described SANS contrast variation.
- Analyzing the relationship between pyrolysis temperature and organic matter transformation based on the described temperature range of 310-370°C.
- Comparing artificial laboratory maturation with natural geological processes based on the described natural maturity sequence.
- Investigating pore space invasion by bitumen during primary migration based on the described mechanism for SANS intensity decrease.
Strengths
- Dataset demonstrates a novel application of SANS technique for a specific geochemical process.
- Includes comparative data from both laboratory pyrolysis and a natural rock sequence.
- Geochemical analysis identified a peak hydrocarbon generation at 340°C within the tested range.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
