Melting in the Deep Earth: Experimental and Computational Data on Mantle Melting

Two published papers from NERC grants NE/I010734/1 and NE/I010947/1 provide data on melting processes under extreme lower mantle conditions. The research, led by Cono Di Paola, John P. Brodholt, and others, addresses fundamental unknowns about melting curves, liquidus phases, and melt compositions in the deep Earth. This data forms a chemical and physical foundation for models of Earth's early crystallization and subsequent evolution.

Use Cases

• Modeling the crystallization of a deep magma ocean based on melting curve data.
• Analyzing the density contrast between minerals and melts in the deep mantle to predict buoyancy.
• Investigating the chemical evolution of the mantle and core based on partial melt compositions.
• Calibrating ab initio models of multicomponent systems under high pressure and temperature.

Strengths

• Data is derived from published, peer-reviewed papers in journals like Nature Scientific Reports and American Mineralogist.
• Research addresses specific, foundational gaps in knowledge about deep Earth melting processes.
• Combines novel experimental results with ab initio modeling for a multi-method approach.

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.
