Ancient helium and tungsten isotopic signatures preserved in mantle domains least modified by crustal recycling ...
The goal of this study is to characterize a suite of mid-Miocene Icelandic lavas that exhibit extremely high 3He/4He (up to 43 Ra, ratio to atmosphere). Whole rock radiogenic isotopes (i.e., long-lived radiogenic isotopes of Sr, Nd, Pb and Hf) were measured, as were whole rock major and trace elemen...

The new geochemical dataset is placed in the context of geochemically characterized ocean island basalt lavas for which 182W has been measured.
