Geochemical Analysis of Australian Petroleum Source Rocks from Ordovician to Cretaceous

A study comparing the geochemical characteristics of four Australian petroleum systems, ranging from the Ordovician to Early Cretaceous periods. The research, sourced from the Australian Ocean Data Network, analyzes source rocks deposited in marine environments with varying terrestrial organic matter inputs. The dataset was last updated on 2026-04-16.

Use Cases

• Classifying source rock composition based on terrestrial versus marine organic matter contributions.
• Modeling petroleum generation potential based on biomarker and molecular compound analysis.
• Reconstructing paleoenvironments using petrological and palynological evidence from source rocks.
• Calibrating biogeochemical models for past atmospheric CO2 levels using terrestrial carbon input data.

Strengths

• Analysis spans four distinct geological periods from Ordovician to Early Cretaceous.
• Compares specific Australian basins including the Canning Basin and the North West Shelf.
• Examines multiple geochemical proxies such as biomarkers, n-alkane distributions, and isotopic compositions.

Limitations

• Data is presented in a PDF format, which may hinder direct computational analysis.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
