Lord Howe Rise Continental Ribbon Tectonic Analysis

An abstract analyzes the Cretaceous formation of the Lord Howe Rise continental ribbon to distinguish between self-organizing and mantle-driven plate tectonic models. The study integrates marine geophysical data, limited dredge samples, and sparse shallow drilling (<600 m below-seafloor) to examine the ribbon's extensional history and igneous rock composition. Research was presented at the 2016 American Geophysical Union Fall Meeting.

Use Cases

• Distinguish between self-organizing and mantle-driven tectonic models using the ribbon's extensional history described in the abstract.
• Analyze the composition and tectonic affinity of igneous rocks within rift basins to understand rifting drivers.
• Integrate marine and satellite geophysical data with dredge samples to resolve the tectonic setting of the submerged continental ribbon.

Strengths

• Focuses on a specific, globally significant geological feature: the Lord Howe Rise continental ribbon.
• Abstract synthesizes multiple data types: marine geophysical data, dredge samples, and shallow drilling.
• Research was peer-reviewed and presented at a major conference, the 2016 American Geophysical Union Fall Meeting.

Limitations

• No primary dataset or structured data (rows, columns) is provided; only an abstract in HTML format.
• Current knowledge is limited by sparse sampling: widely-distributed geophysical data, limited dredge samples, and shallow drilling (<600 m).
• The abstract describes proposed future work (seismic survey, IODP well) rather than presenting completed analysis results.
