Cenozoic Volcanism of the Capel-Faust Basins, Northern Lord Howe Rise

Geoscience Australia survey data identifies volcanic features on the seafloor of the offshore Lord Howe Rise Capel-Faust region. The data includes at least two distinct ages of volcanism: Miocene-Pliocene (approximately 4-7 Ma) cones and Eocene-Oligocene volcanic edifices. Presented at the Australian Earth Sciences Convention in July 2010.

Use Cases

• Map submarine volcanic cone distribution based on swath bathymetry and seismic data.
• Analyze the age and alignment of seamount chains based on described Miocene-Pliocene and Eocene-Oligocene features.
• Study sediment erosion patterns around volcanic cones based on the described moat features.
• Correlate volcanic activity with regional tectonic unconformities based on seismic profile analysis.

Strengths

• Identifies at least two distinct volcanic age groups: Miocene-Pliocene (~4-7 Ma) and Eocene-Oligocene.
• Includes data on the Gifford Guyot (~18 Ma) and references two north-south seamount hotspot chains.
• Based on a recent survey by Geoscience Australia, a national scientific agency.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data files are in PDF and HTML formats, which may require extraction for quantitative analysis.
