Adare Basin Seamount Lava Geochemistry and Petrogenesis

Lava samples from seamounts in the Cape Adare region of the western Ross Sea were collected during a 2007 cruise. The one-year investigation, supported by an NSF award, aimed to determine seamount ages and characterize mantle sources. Data was contributed by the organization AMD_USAPDC and last updated in September 2008.

Use Cases

• Classify lava mantle source types using trace element and isotopic ratio data.
• Model seamount petrogenesis by correlating geochemical signatures with proposed tectonic models.
• Estimate seamount eruption ages through radiometric dating data analysis.
• Assess crustal contamination by comparing major oxide compositions from oceanic versus continental lavas.

Strengths

• Samples collected from a specific 2007 research cruise to the Cape Adare region.
• Data supports a focused one-year investigation into mantle sources and seamount origins.
• Platform tags indicate analysis includes Antarctic Geology, Mantle Sources, and Geochemistry.

Limitations

• Exact sample count, row count, and specific column names are unknown.
• Data is temporally stale, with no updates since 2008.
• Geographic scope is limited to seamounts in the western Ross Sea.
