Rare Earth and 3d Transition Element Geochemistry of Peridotitic Rocks: I. Peridotites from the Western Alps

Abstract
Trace element analyses have been obtained employing RNAA and INAA techniques for 23 bulk-rock specimens and for five pairs of mechanically separated opx and cpx from Western Alpine peridotites. Investigated rocks include 5 garnet lherzolites from Alpe Arami, and spinel (+plagioclase) lherzolites from Finero (2), Balmuccia (7), Baldissero (6) and Lanzo (3). Three pyroxene pairs were analysed from Balmuccia and two from Baldissero.
