Phosphorus Speciation and Metal Abundances in Mafic and Ultramafic Rocks

A collection of mafic and ultramafic rocks includes abundances of phosphorus redox species and metals. The dataset contains peridotites, komatiites, and basalts from a variety of locations and ages. Results show reduced and polymerized phosphorus is present in unaltered rocks, suggesting oceanic crust can be a source of reactive phosphorus.

Use Cases

• Modeling the phosphorus cycle in oceanic crust based on speciation data.
• Comparing geochemical signatures between rock types like peridotites, komatiites, and basalts.
• Investigating the presence of reduced phosphorus species in unaltered mafic rocks.
• Assessing the potential of oceanic crust as a source of reactive phosphorus for biogeochemical studies.

Strengths

• Covers multiple rock types including peridotites, komatiites, and basalts.
• Includes measurements for multiple phosphorus species (phosphate, phosphite, pyrophosphate) and metals.
• Samples are from a variety of locations and ages, suggesting broad geographic and temporal coverage.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
