Porosity Evolution in Biosiliceous Sediments, Monterey Formation, California

A 75.3 KB Excel dataset by Richard J. Behl, last updated April 2026. It details the diagenetic evolution of porosity and microfabric in biosiliceous sediments from the Monterey Formation in California, United States. The description explains transformations in porosity, density, sonic velocity, and rock strength across silica-phase transitions.

Use Cases

• Modeling porosity-permeability relationships based on described pore size and shape evolution.
• Analyzing the impact of burial history on rock strength and cementation based on described discontinuous burial scenarios.
• Correlating sonic velocity with silica-phase transitions (opal-A to opal-CT to quartz) based on described property changes.

Strengths

• Specific porosity ranges are provided, such as 55%-80% for initial diatomaceous sediments and <5% for chert.
• Dataset is openly licensed under CC-BY-4.0.
• Focuses on a well-defined geological formation and process, the Monterey Formation's diagenesis.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
