Testing a Kerguelen Plateau hotspot trace hypothesis
Entry ID:
ASAC_3043
Summary
Abstract:
Metadata record for data from AAS (ASAC) project 3043.
Public McDonald Island is the southern end of a line of submerged islands (seamounts) evenly spaced, similar to the Hawaiian chain. Here, the earth's crust is stationary so the hypothesis is that the source of lava is moving. If zircons are present, they will indicate a continental signal contained in the rocks thus contributing to ...

Taken from the 2008-2009 Progress Report: Variations to work plan or objectives: The scope of the project has grown immensely. While conceived as testing a hotspot hypothesis, emphasis has changed to the continentality issue in pursuit of UNCLOS interests, while the hotspot hypothesis remains a question. Laboratory activity/analysis: Thin sectioning of rocks has been done and descriptions written. Microprobe analysis has been done and is still underway. Zircons separated and prepared for LA-ICPMS work. Results much more interesting than initally envisaged. Several months before results are able to be integrated.
