Analogue Centrifuge Models of Marginal Flexure During Rifting in Afar, East Africa

Frank Zwaan and collaborators at the University of Bern, CNR-IGG, and the University of Florence created this dataset of images and videos from 17 analogue centrifuge experiments. The experiments model passive margin development and rifting tectonics along the western margin of Afar, East Africa, testing variables like brittle layer thickness and syn-rift sedimentation. Detailed descriptions of the experiments and their tectonic interpretation are presented in Zwaan et al. (2020a).

Use Cases

• Training computer vision models to identify fault patterns and deformation evolution based on the experimental image sequences.
• Analyzing the influence of brittle layer thickness (6-20 mm) and viscous domain strength on rift morphology.
• Studying the effects of syn-rift sedimentation on model topography as described in the experimental setup.
• Comparing analogue model results of oblique extension with real-world tectonic observations in Afar.

Strengths

• Includes data from 17 distinct physical experiments, allowing for comparative analysis.
• Experiments systematically varied key parameters like brittle layer thickness (6-20 mm) and applied extension (up to 16.5 mm).
• Conducted at established facilities: the Tectonic Modelling Laboratory of CNR-IGG and the University of Florence.

Limitations

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