Whole-rock chemical and Nd isotopic composition of a Late Proterozoic metasedimentary sequence in Ganderia: Kellys Mountain, Bras d’Or terrane, Nova Scotia, Canada
International audience; The relationship between law-grade metasedimentary and high-grade paragneissic Precambrian rock units in the Bras d'Or terrane of central Cape Breton Island is a long-standing geological problem. Whole rock geochemical and Nd isotopie data from representative components...
