Cenozoic Volcanism of the Capel-Faust Basins: Seafloor Features and Ages

Geoscience Australia survey data identifies volcanic cones, flows, and sills on the seafloor of the Lord Howe Rise Capel-Faust region. The dataset includes analysis of at least two distinct volcanic ages: Miocene-Pliocene (approximately 4-7 Ma) and Eocene-Oligocene features. It was presented at the Australian Earth Sciences Convention in July 2010.

Use Cases

• Mapping seafloor volcanic feature distribution based on identified cones, flows, and sill-related structures.
• Analyzing volcanic age relationships and seamount chain alignments based on described Miocene-Pliocene and Eocene-Oligocene features.
• Studying sediment erosion patterns around volcanic cones based on the described moat features created by currents.

Strengths

• Identifies at least two distinct volcanic ages with specific time ranges: Miocene-Pliocene (~4-7 Ma) and Eocene-Oligocene.
• Includes analysis of multiple data sources mentioned, such as seismic data (survey s302) and swath bathymetry.
• Covers a specific frontier offshore region, the Capel-Faust area of the Lord Howe Rise.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific survey area of the Lord Howe Rise.
