Multi-anvil experiments were performed in static and deformation geometries on olivine polymorphs and Mid-Ocean Ridge Basalt-composition garnetite. Faults were induced by uniaxial compression, with garnetite showing evidence of thermal runaway to melting, suggesting a mechanism for deep earthquakes in subducted slabs.
Use Cases
- Analyze fault induction data from uniaxial compression experiments to compare mechanical behavior between garnetite and wadsleyite samples.
- Correlate evidence of thermal runaway to melting with specific experimental geometries (static vs. deformation) to understand strain localization.
- Model thermal feedback mechanisms using experimental results to assess triggers for deep earthquakes in the transition zone (~500-660 km depth).
Strengths
- Data originates from controlled multi-anvil high-pressure experiments performed by the British Geological Survey.
- Experiments cover two distinct sample types: olivine polymorphs and MORB-composition garnetite.
- Analysis provides specific geological context for deep earthquake mechanisms in subducted slabs at ~500-660 km depth.
Limitations
- Sample data, column definitions, and dataset size (rows, file formats) are unavailable, limiting immediate analytical utility.
- Experimental scope is focused on specific mineral compositions (olivine polymorphs, MORB garnetite), reducing generalizability.
