Several diagnostic chemical characteristics of an uncommon Aleutian magma type support a
proposed origin that involves a small amount of partial melting of subducted Pacific ocean …

Abstract The Hawaiian–Emperor Seamount Chain (ESC), in the northern Pacific Ocean, was
produced during the passage of the Pacific Plate over the Hawaiian hotspot. Major and trace …

Abstract The Pb and Sr isotope ratios of Plio-Pleistocene volcanic rocks from the Aleutian
volcanic arc are used as tracers of the lithospheric subduction process at the converging …

The radiogenic isotopic ratios of Sr, Nd, Hf, and Pb in basaltic lavas associated with major
hot spots, such as Hawaii, document the geochemical heterogeneity of their mantle source …

Ice-rafted debris (IRD) in marine sediments provides a valuable direct indicator of the
presence of glacial ice at sea level on surrounding continents, and is therefore a useful tool …

A correlary of sea floor spreading is that the production rate of ocean ridge basalts exceeds
that of all other volcanic rocks on the earth combined. Basalts of the ocean ridges bring with …

Late Cenozoic ash deposits cored in Deep Sea Drilling Project Leg 19 in the far northwest
Pacific and in the Bering Sea have altered to bentonite beds. Some bentonite layers were …

The Hf and Nd isotopic compositions of 71 Quaternary lavas collected from locations along
the full length of the Aleutian island arc are used to constrain the sources of Aleutian …
