Abstract
Sixty-three rocks of the pelitic Devonian Littleton formation of New Hampshire have been analyzed spectrographically for trace elements. The samples represent all grades of metamorphism from shales to sillimanite schists and gneisses. The average concentrations and standard deviations in ppm are: Ga, 19, 6.3; Cr, 110, 33; V, 120, 39; Li, 110,104; Ni, 64, 26; Co, 18, 6.6; Cu, 18, 18; Sc, 14, 7.4; Zr, 200, 73; Y, 45, 20; Sr, 710, 310; Pb, 24, 12. Be, Mo, Sn, La, and Ag were usually below the sensitivity limits of 30, 10, 20, 100, and 1 ppm respectively. Ba almost always exceeds 1000 ppm.
