Helium and lead isotope geochemistry of oceanic volcanic rocks from the East Pacific and South Atlantic

Graham, David W.Massachusetts Institute of Technology and Woods Hole Oceanographic Institution1987

… precise reconstruction of He-Pb isotope relationships in volcanic source regions is complicated by post-eruptive radiogenic ingrowth of 4He in non-zero age basalts, by pre-eruptive radiogenic ingrowth of 4He in magmas with elevated (U+Th)/He, by multi-stage fractionation processes involving …
