Lord Howe Rise Continental Ribbon: Seismic and Geophysical Data on Gondwana Rifting

Geoscience Australia Data provides geophysical data related to the Lord Howe Rise, a continental ribbon formed during the Cretaceous fragmentation of eastern Gondwana. The dataset includes marine and satellite geophysical data, dredge samples, and shallow drilling records, with a recent deep crustal seismic survey and a proposed IODP deep stratigraphic well offering new insights. The abstract was presented at the 2016 American Geophysical Union Fall Meeting.

Use Cases

• Modeling the tectonic evolution of the Lord Howe Rise based on geophysical data mentioned in the description.
• Investigating the drivers of continental rifting (self-organized vs. mantle-driven) based on the extensional history and igneous rock composition described.
• Analyzing the stratigraphy of Cretaceous rift basins to understand the fragmentation of eastern Gondwana.
• Integrating marine seismic, satellite, and dredge sample data to study submerged continental ribbons.

Strengths

• Includes data from a recent deep crustal seismic survey, as mentioned in the description.
• Leverages a proposed IODP deep stratigraphic well for future stratigraphic analysis.
• Abstract was peer-reviewed and presented at the 2016 American Geophysical Union Fall Meeting.

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 data_gov_au, focusing on the Lord Howe Rise region.
