Wide-angle seismic data from ocean bottom seismographs, gravity data, and deep marine reflection profiling data define crustal-scale features along the Vulcan transect in northern Australia. The dataset, sourced from the Australian Ocean Data Network, outlines the crustal and upper mantle architecture between the Precambrian Australian craton and the Timor Trough. It includes interpreted crustal thickness values, such as 35 km near the coast and 26 km under the outer shelf.
Use Cases
- Model crustal thinning across continental margins based on interpreted thickness values from 35 km to 26 km.
- Analyze basin-forming processes based on elevated P-wave velocities (7 km/s) suggesting intrusive mafic rocks.
- Study deep crustal detachments or intrusions based on strong reflections at approximately 13 km depth.
- Investigate upper mantle compositional boundaries based on seismic energy reflected from 38-45 km depth.
Strengths
- Includes multiple geophysical data types: wide-angle seismic, gravity, and deep marine reflection profiling.
- Provides specific crustal thickness measurements, such as 35 km near the Yampi Shelf and 26 km under the outer shelf.
- Contains interpreted depth values for features like mid-crustal reflections (~13 km) and mantle boundaries (38-45 km).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
