Wenchang Formation Geochemical Data for Source Rock Analysis in Pearl River Mouth Basin

Geochemical data from the Paleogene Wenchang Formation in the Lufeng 15 Sub-sag, Pearl River Mouth Basin, China. The dataset, created by Yangdi Zheng and last updated in March 2026, contains elemental and organic geochemistry measurements used to reconstruct paleoenvironments and assess controls on hydrocarbon source rock quality. It is a 308.9 KB XLSX file shared under a CC-BY-4.0 license.

Use Cases

• Modeling the relationship between paleo-water depth and source rock quality based on Sr/Ba ratio data.
• Assessing paleoproductivity controls on organic matter accumulation using P/Ti ratio data.
• Evaluating paleoredox conditions for organic matter preservation based on V/Cr ratio data.
• Identifying optimal 'high productivity - strong preservation' zones for hydrocarbon exploration within lacustrine sequences.

Strengths

• Data includes quantitative geochemical proxies like Sr/Ba, P/Ti, and V/Cr ratios for environmental reconstruction.
• Analysis is focused on a specific, well-defined geological unit (Wenchang Formation) and location (Lufeng 15 Sub-sag).
• Integrated analytical approach combining palynology, organic geochemistry, and elemental geochemistry is described.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset's 308.9 KB size suggests a limited scope, likely containing summary or sample data rather than a large measurement series.
