Tectonic Magmatic Setting Comparison - Ocean Islands (DeBarba and Scheland, 2015)
-
Description
-
When it comes to the tectonic magmatic setting of these two localities there is not much to compare beyond the physical location on the lithsopheric plate. They are both situated on the Pacific plate. The Hawaiian Islands are north of the equator and east of the international date line. The Samoan Islands are just south of the equator and just east of the international date line.
They are both examples of mantle plumes manifesting themselves on the surface as shield volcano islands. The Samoan Islands are however approaching the Mariana Trench which may have geochemical or physiographical implications.
