Collaborative Research: Geochemical transect from oceanic Adare Basin to adjacent continental Adare Peninsula: implications for the origin of intraplate (HIMU-like) alkaline magmas
Entry ID: SIO_BGSU_ADARE_GEOCHEM

[ Update this Record ]

Summary
Abstract: Detailed analytical studies are still being conducted on Adare Basin samples, but preliminary results for their major element, trace element and Sr-Nd-Pb isotopic compositions resemble those of volcanic rocks from ocean islands with a distinct, hotspot compositional affinity. Combined with literature data for volcanic rocks from the adjacent continental margin of West Antarctica, the volcanic ... View entire text

Purpose: The over-arching objective of this project is to compare oceanic and continental volcanism in the northwestern Ross Sea, Antarctica, in order to distinguish variations in mantle source and processes responsible for the formation of alkaline magmas in this region of the West Antarctic rift system. Specific purpose of this work include:

To determine the age of oceanic basaltic volcanism within the ... View entire text
